If you have had a chance to read my review of the Mossberg 20-gauge Tactical shotgun Mossberg 500 20-Gauge Tactical Shotgun (54300), one of my peeves with shotgun was the stock that was provided with the shotgun.The LOP with the stock that came with the shotgun was 11-inches without the butt pad. Adding a one-inch spacer took the LOP out to twelve-inches. Mounting the butt pad extended the LOP to 12.75-inches, which was still too short for my comfort. A LimbSaver slip-on recoil pad was added to provide 3.75-inch of LOP. This was more like it, but still shorter than my desired 14.25-inch to 14.75-inch LOP. Why Mossberg decided to place a “youth” stock on a “tactical” shotgun with a 20-inch barrel is beyond me, but they did. I do admit to having a long reach and, with a total six-foot wingspan, most stocks feel too short. I ordered a “normal” stock from Mossberg, a black polymer unit, to replace the erector set that Mossberg called a stock. With the new stock, according to Mossberg, I could expect a LOP of 13.75-inches. That was more to my liking.
The grip pattern of the new stock was not as textured as the original stock. The new stock did; however, provide a better match with subtle pattern of the forearm.
Changing out a Mossberg 500 stock is a pretty simple affair and is well worth the 10 minutes or so out of my life. A standard Phillips screwdriver tip provides for the removal of the butt-pad and spacer screws, and a long-shank, large, flat-tipped screwdriver (or a 3/8” socket) makes removal of the stock mounting bolt a quick effort.Place the new stock in place and tighten the mounting bolt, but do not over-tighten. The receiver of the Mossberg shotgun is aluminum and so are the stock mounting threads. Snug is all that is needed. Attach the butt-pad (with the provided screws) with a Phillips screwdriver and, once again, I had an operational shotgun. Not only did I have an operational shotgun, but an operational shotgun with a LOP within my operational range. The new stock (with butt pad) gave me a 13.75-inch LOP. Add the LimbSaver clip-on recoil pad and the LOP moves out to an uncompressed 15-inches. For me, a 15-inch LOP is perfect when I am just wearing a shirt or light vest. With a medium to heavy coat, I simply pull off the LimbSaver and operate with the 13.75” LOP. The LOP does not matter if I am wearing, or not wearing, trousers.
Mossberg supplied a short stock with the long-barreled 20-gauge Tactical shotgun, yet they offer a standard stock with the shorter barreled shotguns like the 500 Tactical 6-shot. However, and in Mossberg’s defense, an adjustable stock version is available for the same shotgun that I have (500 Tactical – Adjustable Stock (#54301): http://www.mossberg.com/product/500-tactical-adjustable-stock-54301/) and that provides a 10.75″ – 14.25″ LOP. While it is an adequate LOP range for most folks, I prefer full-size stocks with a fixed LOP. Besides, a hollow full-size stock allows me to stock the stock with survival supplies (fire making materials, spare flashlight batteries, and long Slim Jims) – just in case.
As with any firearm, you must make the firearm fits your requirements. Exchanging stocks on the Mossberg 500 8-shot Tactical 20-gauge was my way of making the shotgun fit me and my needs, and I don’t think that I need to go farther than that.
And in closing, if you need a short Mossberg 20-gauge stock with limited adjustment capabilities (11-inches to 12.75-inches), I just happen to have one.
