Scope Rings – A Balancing Act

Scope Mounting with Scope Rings

Scope Mounting with Scope Rings

This article is for us common folk who, for whatever reason, want to mount a scope on their favorite rifle or carbine. This article is not intended to be a comprehensive guide to scope rings nor how to mount a scope, but may provide you with enough information to increase your knowledge about scope rings and proper mounting of them, by learning about my mistakes.

Lately, I have come across the issue of mounting a scope. Why this is an issue now, I don’t know. I have mounted quite a few scopes in my time, but I have simply become more cognizant about scope rings, bases, and how important these two items mean in ‘properly’ mounting a scope to a rifle, carbine, or even a pistol.

It is common practice to ensure that the scope is mounted as low to the barrel as possible. Scope rings heights normally come in three height flavors; low, medium, and high. There are, of course, extra-high and ultra-high scope rings. Scope height; however, is only part of the equation with proper cheek position on the stock in relation to the scope and the eye relief of the scope playing the other factors. For bolt-action rifles, bolt handle clearance to the ocular lens housing is another consideration.

Scope bases:

Essentially, there are three types of scope bases; Dovetail Redfield), Weaver, and Picatinny.

Dovetail (Redfield)

Dovetail (Redfield) Scope Ring Example

Dovetail (Redfield) Scope Ring Example

One of the oldest scope mounting systems is known as dovetail. The rotary dovetail is one of the oldest methods for holding a scope. This scope base system is heavy and strong. These bases and rings are called Redfield style, as they were patented by John Redfield. The dual dovetail is sturdy and is used by hunters with rifles that have strong recoil.

The Weaver scope base mounting system is a system that utilizes a flat rail with crosswise slots. This base is 7/8-inch wide and accepts Weaver style rings. Crosswise, protruding rails beneath the rings help prevent movement due to recoil. The Weaver rings are easily detached from the base without removing the scope. They can then be reattached. This type of base allows for easy swapping of scopes from one gun to another.


Picatinny Rail Example (Sight Riser)

Picatinny Rail Example (Sight Riser)

The Picatinny scope base is a one- or two- piece design made of steel. Badger Ordnance manufactures a two-piece base using the Picatinny system, available in a couple of different MOA’s (minutes of angle). It secures scope rings in place with more flexibility than some other ring-and-base systems. The Picatinny is used on both tactical and sporting rifles. This scope base is easily installed since it uses factory-drilled scope base holes and screws. It will accommodate both right- and left-hand receivers. This scope base can be adjusted to several different lengths of scope bodies. This is the most versatile of scope bases. In the 1960s, the Picatinny Arsenal in New York set about creating a stronger scope base for heavy weapons. The result was a base that has several uses in law enforcement and the military; heavy civilian use has increased the popularity of these mounts.. The base can be also used to hold flashlights, night vision devices and laser sights firmly in place.

AR-based rifles (and others) commonly employ the Picatinny rail in their design.

Scope Rings:
Scope rings, as with scope bases, are manufactured for Dovetail, Weaver, and Picatinny rails. Dovetail-based scope rings only work with Dovetail slots. Weaver rings will fit Picatinny bases, but Picatinny rings are not compatible with Weaver bases, as the mounting key in the Picatinny style scope rings is thicker (square) than that of the Weaver scope ring. However, Weaver style base manufacturers have been cutting thicker slots in their bases to accommodate picatinny rings, and picatinny ring manufacturers have started to put smaller recoil lugs (mounting keys) on their rings. The mounting key is what is actually inserted into the mounting groove of the Weaver or Picatinny base.

Scope rings also come in aluminum and steel and can be permanent mounts or quick-detachable mounts (my favorite). Scope rings may also be in various finishes, such as; anodized aluminum, matte, high-gloss, or stainless steel.

Numerous manufactures of scope rings and bases abound to include; Weaver, Redfield, UTG, Leupold, Burris, Warne, Millet, Talley, and others. Scope rings range from cheap in price to expensive, high-end models. Generally, expensive, high-end scope rings and mounts are precision machined with closer regard to tolerances. However, there are many scope rings in ‘reasonable’ prices ranges that are excellent performers.
Scope rings can be singular units or modular.

Scope rings must be sized to the diameter of the scope tube being mounted. Popular scope tube diameters are one-inch (25.4mm), 30mm, and 34mm. It is important that the correct scope ring diameter be matched to the scope tube.

Some scope rings may require ‘lapping’ to properly fit the scope tube. Ideally, the rings should place equal pressure on the scope tube throughout the ring’s mounting surface. Lapping removes imperfections in the scope ring mounting surfaces to prevent damage to the scope. Wheeler has a complete kit (Wheeler Scope Mounting Kit Combo, 1-Inch/30mm) that provides everything necessary to mount a scope the correct way, including an instructional DVD. Proper scope installation is critical to the accuracy of your firearm. Get the most accuracy possible out of your gun by ensuring proper scope installation. The Wheeler Alignment Bars, Lapping Bars and Lapping Compound allow you to achieve the perfect fit between scope and rings. Securing Fasteners properly is critical to accuracy as well. Precisely controlled torque along with thread locking compound will keep your scope held securely in place. Professional grade bits and the F.A.T. Wrench are the perfect combination to properly secure fasteners without deformation.

Two separate front and rear scope rings are the most common.

Scope rings are generally top-clamp and side clamp configurations.

Offset Scope Mount Example

Offset Scope Mount Example

Modular scope rings, quite common in Picatinny mountings, incorporates a picatinny mounting base with integral front and rear scope rings incorporated into the design as a single unit. Offset modular units provide an easy means to adjust for eye relief, as they ‘offset’ the scope from the scope’s original mounting point.

Some scope rings have padded inserts to protect the scope’s finish.

Scope Height:

Scope Ring Height Measurement

Scope Ring Height Measurement

Scope height is determined by the RH (Ring Height), which is calculated from the top of the base (or integral dovetail) to the bottom of the scope tube.

Common scope heights for 1-inch scope tubes are as follows:

  • Low = .250-inch
  • Medium = .375-inch
  • High = .525-inch
  • Extra High = .650-inch
  • Ultra-High = .935-inch

Common scope heights for 30mm scope tubes are identical except that the Ultra-High scope height is .850-inch.

50mm scopes will generally use high rings. Heavy barrels may require extra-high. Mediums may occasionally work with standard contour barrels.

42-45mm scopes will mostly use medium rings with standard contour barrels.

40mm scopes will generally use low rings with standard contour barrels.

Flattop rifles will need super-high rings with an optical center of 1.5 inches or just slightly less for a proper cheek weld.

Critical Scope Dimensions:

Aside from the scope tube diameter, two other dimensions are critical when deciding what scope rings will be used to mount the scope; the diameter of the objective lens housing (the lens nearest the target) and the diameter of the ocular lens housing (the lens closest to the eye), but not for the same reason.

Objective Lens:

Example of a Large Objective Lens

Example of a Large Objective Lens

The objective lens housing must clear the barrel of the firearm, but not just the lens housing, but any attachments such as scope covers (regardless of type; for example, flip-up or slip). The spacing is not critical but a space must exist between the objective lens housing and the barrel. High power scopes may incorporate a large objective lens (for example, the Leapers 6.5-20×56), which requires tall scope mounts in order to ensure that the objective lens (the 56 part of the scope) clears the barrel. Considering that the M24 Sniper Weapon utilizes a Leupold Ultra M3A 10×42mm fixed power, or Leupold Mk 4 LR/T M3 10×40mm fixed power scope, and which are used by trained snipers, a large objective lens only complicates matters of mounting a scope.

For most lever-action rifles, providing the proper clearance between the objective lens housing and the barrel is adequate to prevent the bolt, upon levering the action, from interference with the ocular lens housing. I normally mount a 3-9×40 magnification lens scope on low rings with my Marlin Model 336c lever guns with no clearance problems. Large objective lens scopes usually means higher scope mounting rings for the objective lens to clear the barrel (and also any mid-barrel mounted sights).

Ocular Lens:
With semi-automatic and pump action rifles, the diameter of the ocular lens is not a concern as far as mounting. With lever-action and bolt-action rifles; however, the bolt must clear the ocular lens housing. Recently, I found that with the Ruger M77/357 carbine, the 90-degree bolt of the carbine when used with one scope would rub against the ocular lens housing ever so slightly. Enough so; however, that the scope was changed out with another scope that has a slightly smaller ocular lens housing and enough clearance was available between the ocular lens housing and the bolt handle knob was adequate to prevent rubbing during normal bolt operation. The replacement scope was a higher power scope than what was originally mounted, which resulted in a larger objective lens.

Scope Length:

Scopes Come In Various Lengths

Scopes Come In Various Lengths

A second consideration for the scope is the scope length. Scopes come in a wide variety of lengths and allow for a lot of back and forth movement in the scope rings to achieve the correct scope picture (eye relief) before tightening everything down. Tactical scopes, on the other hand, are usually short in the scope tube length department (of course, there are exceptions), which negates a lot of back and forth movement. With some scopes, there may be long ocular lens housing and an additional housing to accommodate reticule lighting control that also may dictate the type of scope rings used for mounting the scope. Some scopes may allow the use of ‘quad mount’ scope mounts (4-scope mounting screws per mount and even six-screws per mount), while other scopes may only allow one or two actual scope tube mounting screws per mount.

While you may have achieved a suitable distance between the objective lens housing and the barrel of the rifle that does not mean that the scope height is correct for your eye at the ocular end. It is best to have the ocular lens a little high than a little low, which forces you to scrunch your cheek low and into the stock in order to obtain a correct scope picture. A slightly higher ocular lens can be accommodated by the use of a cheek rest (adjustable or slip-on) to raise the eye to the correct level for a perfect scope picture. Note that when using a cheek rest, the rest must not interfere with the bolt’s action (on lever-action and bolt-action rifles).

Determining Scope Ring Height:

I normally keep three inexpensive scope rings on hand; low profile, medium profile, and high profile. These mounts allow me to rest the scope in the mounts for sizing purposes. These are only used to size the scope and are not mounted to a scope. I will profile the scope against the rifle while the rifle is locked into a sight vice.

I use a slice of an old mouse pad, which is approximately 1/16-inch thick, to act as a rest for the objective lens of the scope and then rest the objective lens housing on the ‘spacer’ to provide the minimum clearance between the objective lens housing and the barrel. The scope is then raised to as close to parallel with the rifle as I can. Then, using a steel rule, I’ll measure the distance between bottom of the scope tube and the top of the scope base. This provides an approximate height for the scope. Next, I’ll mount the closest scope rings that fit the approximate measurement. The scope is then placed in the rings and the tops are loosely fitted to the scope. In general; however, I can approximate the required scope ring height simply using the guidelines set forth earlier in this article regarding scope height.

I then move rearward and try out the approximate eye relief and cheek rest. For a bolt-action rifle, this is a good time to check for clearance between the ocular lens housing and the bolt handle during cycling. If all seems favorable, it is time to select the desired scope rings to use – and I have my favorites (your favorites may differ from mine).

I have come to appreciate Warne scope rings and they are my first choice for QD and permanent mount scope rings. I have also used UTG and Weaver “quad’ scope mounts successfully. For my latest project, mounting a scope to the Ruger American in .223 caliber, I had selected the Center Point 4-16×40 power scope that came with ‘quad’ scope mounts that were already mounted to the scope. I plain did not like them after I mounted the scope the scope to the rifle in a trail fitting. The scope sat too high for both the ocular lens and the objective lens for my liking. The eye relief of the scope was; however, as close to perfect for me as possible. I have used Center Point scopes in the past and I have never been disappointed in them. But, I digress.

Warne Medium Height 1" Scope Rings

Warne Medium Height 1″ Scope Rings

I ordered a set of Warne 1-inch, medium-profile, permanent-attach rings from Amazon. Although the scope height is only .375-inch with these rings, the Weaver scope bases already mounted to the Ruger American allow the use of medium-profile scope rings with the Center Point 4-16×40 power scope. The Warne mounts offer four Torx screws per ring for securing the scope. Although a Torx wrench is provided with the scope rings, the Wheeler Fat Wrench and a suitable Torx bit provides the necessary 25-inch maximum pounds of torque needed to secure the scope tube without worrying about applying too much torque the mounting screws, which is common when using right-angle Torx or Hex-head tools.

Warne Maxima Series 1" QD Scope Rings for AR

Warne Maxima Series 1″ QD Scope Rings for AR

I also wanted to replace the scope rings on a UTG 3-9×40 Generation 2 Sniper Scope for my ARs. Initially, I had used the rings that came with the scope and a set of sight risers in order to clear the rear flip-up sight; I wanted a one piece mounting arrangement and a set of Warne Maxima Series Aluminum, Ultra-High height (.935), matte finish rings were ordered. These rings are ideal for mounting optics to a MSR while keeping the rear flip-up style sight.

Some folks like ‘see-through’ scope mounts. These scope mounts allow the shooter to view the iron sights but keeps the scope mounted; the shooter simply lifts the head into a position behind the scope when needed. Higher scope mountings; however, affect the scope’s effectiveness at close ranges. A lot of people are discovering that low-power, variable (or even fixed magnification scopes) are more flexible than high power scopes. 2-7×32 and 3-9×40 magnification scopes are common and both can use the same scope rings to provide objective lens-to-barrel clearance in most cases.

In modern sporting rifles, like AR-based rifles and carbines, the optic sight height can affect ‘co-witnessing’ of the iron sights, but that is another topic in itself. For this article, the emphasis is on scopes that will be mounted close to the shooter; short and intermediate eye relief scopes fall into this category.

Eye Relief Chart

Eye Relief Chart

For a shooter, eye relief is also a safety consideration. If the eye relief of a telescopic sight is too short, leaving the eye close to the sight, the firearm’s recoil can force the optic to strike the skin around the shooter’s eye, leaving a crescent-shaped cut. This is frequently called the “scope eye” due to the obvious source of the cut. Typical eye relief distances for telescopic sights are typically between one and four inches (25 to 100 mm).

Mounting and Leveling, Leveling, and Leveling, and Leveling, and…:

The type of scope ring will dictate how you mount and level the scope. For top-secured scope rings, the bottom of the scope ring is positioned in the rail and the scope is then set into place within the rings. With these types of rings, I always place the top of the mounts loosely in place with the provided screws; this prevents the scope from falling out of the scope rings while I set up the scope/rifle combination.

With the Warne type of scope ring, the entire ring is disassembled to allow the rings to surround each side of the scope housing. Then it is loosely reassembled enough to allow the scope to slide freely within the rings. (The QD mounts Warne scope rings can then be adjusted to the desired position on the rail and just adjusted until they are snug against the rail to prevent the scope rings (and scope) from falling off the rifle.)

With either style of ring, tighten the scope mounts just enough to allow the scope to drag slightly through the rings. This is where the fun really begins.

Adjust the Scope for the Correct Eye Relief

Adjust the Scope for the Correct Eye Relief

Don’t worry about the reticule position at this point, but simply turn the scope within the rings until the elevation housing is near vertical. What you want to do is to adjust for eye relief. That means sliding the scope back and forth in the scope mounts to achieve the proper distance from the ocular lens to the eye for the perfect scope picture. This needs to be done by assuming a standing, bench rest, and prone position with the rifle properly mounted in a shooting position. Adjusting for a ‘mean’ eye relief may take several tries. The objective is that regardless of the firing position that you assume, the scope will be as close to the needed eye relief as possible with only minor adjustments of the head to obtain the correct ‘scope picture.’ If bench shooting is your forte, adjusting for the correct eye relief in this position may be your goal. However, if you may find yourself in various shooting positions, then adjust for eye relief as best as possible. The idea here is to move the scope to your eye and not your eye to the scope. With that said; however, with collapsible stock, like those on MSRs, the stock can be adjusted to provide the eye relief necessary to properly obtain a perfect scope picture.

Once you believe that you have the eye relief adjusted, use a pencil or washable felt pen to mark the position of the scope to one of the rings – front or rear, no matter as long as you can return the scope to that position in the ring.

Remove each scope mounting screw (not the base) and add a dab of Lok-Tite 242 (blue). This will help prevent the scope screws from backing out under recoil but still allows the screws to be removed easily at a later time (NO RED LOC-TITE PLEASE!).

Now, it’s time to lock the rifle in a good sight or rifle rest for leveling. From this point, some patience is also going to help. I use an inexpensive Winchester Sight Vise unit that I purchased from Wal-Mart a long time ago, but any good rifle rest will work as long as you can secure the rifle.

Wheeler Level-Level-Level System

Wheeler Level-Level-Level System

If you don’t have a Wheeler Level-Level-Level (See: Sources for Stuff at end of article) at your disposal, any small bubble level will do. With that said, you will also find many uses for the Wheeler Level-Level-Level other than mounting scopes so get one anyway. They are usually available at local gun shops or on-line. I have even seen them at some Wal-Marts.

Wheeler Professional Reticle Leveling System

Wheeler Professional Reticle Leveling System

Sometimes; however, and depending on the rifle, there may not be enough room to mount two levels; one for the rifle, and one for the scope. I have found this to be true when using low-mount scope rings. Here is where a handy tool comes into play; the Wheeler Professional Reticle Leveling System (see, Sources for Stuff at end of article).

The Wheeler Professional Reticle Leveling System is a precision tool and technique designed to allow a scope to be perfectly leveled on any firearm with ease. CNC machining, factory adjusted calibration set screws, anodized aluminum construction and protective molded case put this instrument in a class of its own. The Barrel Clamp Level is attached to the guns barrel while the smaller Reference Level is placed on scope base, bottom half of a ring or other flat surface perpendicular to the vertical axis of the gun. The gun is then rotated until the Reference Level is aligned. The tuning adjustment knob on the Barrel Clamp Level is then turned until its level is centered to match the Reference Level. At this point the Barrel Clamp Level is calibrated to the guns axis. The Scope can be installed loosely and the Reference Level placed on top of the scopes turret cap. The scope is rotated until the Reference Level is aligned with the Barrel Clamp Level and then simply secured in place. The Wheeler PRLS is the most effective instrument available for precision scope alignment.

With flat top rifles, like those with Weaver and Picatinny rails, there may be more than enough mounting rail to use the Wheeler Level-Level-Level system, but if you are like me and mount scopes on anything a scope can be mounted, the Wheeler Professional Reticle Leveling System is a worthwhile investment.

First things first – level the rifle for and aft and side to side. This may take repeated attempts until you get the rifle as level as possible. The Wheeler Level-Level-Level or the Wheeler Professional Reticle Leveling System (see, Sources for Stuff at end of article) allows you to monitor the level of the rifle as you level the scope.

Move the scope (if it had moved) to the eye relief mark that you made earlier. Place the small level on top of the elevation turret (or cap). Slowly rotate the scope within the rings until level. At this point ensure that the bottom scope mount is secured to the scope base. Note: Move the scope bases forward until they stop in the rail. Then tighten the scope base against the rail while holding each scope base tight against the forward edge of the slot to guard against skewing the mount. Double-check that both the scope and rifle are level. If not, readjust as necessary.

NOTE: When using Weaver and Picatinny scope mounts, and when attaching the scope mounts to the base, ensure that the scope rings are pushed all the way forward (toward the muzzle) in the slot before tightening.

Return, if necessary, the scope to the eye relief marks that you made earlier.

Tighten each scope ring screw a little at a time in a staggered fashion until the scope cannot be moved in the rings. Using the Wheeler Fat Wrench and appropriate bit, tighten each screw in 5-inch pound increment until the desired torque is achieved. On most rings this would be about 20-inch pounds (Warne steel rings require 25-inch pounds). If in doubt about what torque setting to use, contact the manufacturer or visit the manufacture’s web site. For example, I recently e-mailed Ruger about torque specification on the scope rings provided with the Ruger M77/357. Ruger responded the next day (20-inch pounds on the scope rings and 30-inch pounds for the base screws). Good customer service!

Double-check the scope alignment after each torque setting. If you are satisfied, move on to completing the tightening until the final torque setting is achieved.

What you should have is a scope that clears the objective lens housing to the barrel, level and plum scope reticules, and the most perfect eye relief that you can achieve from different shooting positions with the proper cheek weld. If the scope is somewhat high for you, but not enough to warrant a different set of scope rings, you may opt for a removable cheek rest (I use these more often than not because no mounted scope is perfect), purchase an adjustable cheek rest that can be affixed to your stock, or spend a gaggle of money finding a stock with a raised or adjustable comb.

The rifle is now ready for bore-sighting, which is a topic unto itself and beyond the scope of this article.

If this sounds too much for you, deliver the rifle, scope, and scope rings to a competent and qualified gunsmith for mounting and bore sighting. Consider; however, that a competent gunsmith will charge you for the service of mounting a scope. For myself, I gain considerable satisfaction knowing that I can do it myself and have the tools to do it again – cost, priceless.

Picatinny Rail Mounting Shortcut:

Leveling a Scope With a Sight Riser and a Flat Surface

Leveling a Scope With a Sight Riser and a Flat Surface

Here is a quick shortcut that you can use to mount a scope to a Picatinny rail without using the rifle as a base. All you need is a level surface and a detachable sight riser like the UTG 1-Inch High 13-slot Hi-profile Full Size Riser Mount (see, Sources For Stuff at end of article).

The UTG 1-Inch High 13-slot Hi-profile Full Size Riser Mount is a 13-slot unit.

Remove the side mounting screws but not the tension strip. Then, lay the scope riser on a flat, level surface (I use a carpenter’s level to verify a level surface). Mount the scope rings and scope rings to the riser. Level the scope to the table level, tighten everything down to the specified torque, remove the scope and scope rings from the riser as a unit and transfer to your favorite MSR or other rifle that incorporates a Picatinny rail. In most cases, you will be as close to correct as you need to be.

You can also use this same method for Weaver mounts, as they will fit the slots in a picatinny rail. For Weaver mounts, measure the distance from center-to-center of the recoil lug slots and transfer this measurement to the Picatinny rail.

Of course, double-check for the correct eye relief, reticule alignment, and scope height from the barrel.

Some Other Thoughts on Scope Rings:

If you purchase a scope that has scope rings provided with it, assess the rings for worthiness. The scope rings may be adequate, but the scope mounting screws may not be. For example, one scope that I purchased had Phillip-head screws for mounting. Appropriate hex head screws were found and the Phillip-head screws were canned. The mount itself has been on the rifle for five years now.

Don’t be afraid to not use provided scope mounts. It’s worth the money to provide you piece of mind with good scope mounts.

Regardless of the type of scope ring/mount that I am working with, I tend to apply a very thin coating of grease to the mounting rail where the scope rings are mounted. This provides a hydraulic seal to prevent moisture from creeping between the mounting points, also acts as an additional ‘cushion’ against recoil, and helps to prevent scarring of your favorite rilfe from metal-to-metal contact from the scope ring mounts.

Amazon is a good resource for scope mount reviews.

If the words ‘shimming’ and ‘lapping’ scare you, deliver the rifle, scope, and scope rings to a competent and qualified gunsmith for mounting and bore sighting. In some cases, installing shims or lapping the scope mounts for a ‘perfect’ fit may be necessary. A scope alignment tool may also be useful in extreme cases. The Wheeler Fat Wrench (see, Sources for Stuff at end of article) is indispensable.

Wheeler Scope Mounting Kit

Wheeler Scope Mounting Kit

If you really like to tinker like a semi-professional scope mounting person, I can heartily recommend the Wheeler 540-127 Scope Mounting Kit with storage case (see, Sources For Stuff at end of article). The kit provides a DVD on scope mounting, the Level-Level Level, scope alignment bars, scope lapping rod, lapping compound, Lok-Tite, and the Fat Wrench with several bits.

I can also recommend the Wheeler Professional Reticle Leveling System (see, Sources for Stuff at end of article) as a substitute (or to work with) the Wheeler Level-Level-Level system.

To Summarize:

The purpose of scope rings is to mount a scope to a rifle and to ensure that it stays in place under recoil.

Scope rings need to be properly fitted to the scope and the rifle. They need to be high enough so that the objective lens housing clears the barrel, but not too high as to negate proper eye alignment with the ocular lens.

There are many scope rings available and deciding which scope ring is right for your shooting needs can be a daunting task. Once I find a good scope ring, I tend to stay with it under I find something better for a decent price. With that said, I would not use ten-dollar scope rings to mount a one-thousand dollar scope (not that I need a scope of that price).

Updating the AR Scope Mounting

An ideal mounting system secures your optical device to your firearm as low as comfortably possible, with the fewest parts necessary. More parts equal more chances for something to go wrong. Solid steel mounts are the strongest, but in many cases, aluminum will serve perfectly well. See through rings are notoriously weak, and points of impact change from bumps or carrying are common. With a good scope with low enough minimum magnification; your iron sights will never be used.

Winchester Sight Vise

Winchester Sight Vise

A gun vice is necessary to secure the firearm while installing scope rings and scope. I use a simple Sight Vise by Winchester (see, Sources for Stuff at end of article) that seems to work well (with some coaxing at times).

Decide, before you mount the scope, if you want the scope to be quickly detached for cleaning the rifle, stored separate from the rifle, or to be mounted on another rifle. For example, my UTG 3-9×40 Generation 2 Sniper Scope can be removed from one AR and mounted on a second one if need be. I run a UTG red/green dot sight on my Windham Weaponry ‘SRC’ and this sight can be quickly detached and the UTG 3-9×40 Generation 2 Sniper Scope quickly mounted.
