ATI Gunstocks Adjustable Hunting Stock for pump shotguns are American made, well-thought out and offer a lifetime guarantee. This stock fits all three major American brands—Winchester, Remington and Mossberg pumps. It comes with stock and fore end and a bag of adapters.
I first tried it on a Remington 870. For installation, you will need a #2 Phillips screwdriver and a 1/2” socket wrench. Installation is reasonably straightforward, and the instructions are quite clear with good photos that cover disassembly of the original as well.
The stock easily adjusts for 13-14.5 Length Of Pull in four stops, which is good for customizing to the shooter, or to adapt for clothing, but doesn’t collapse nearly as much as an AR carbine type stock. I found the full length to be comfortable, and the minimum length was adequate for my average sized wife (5’5”) but not short enough for youths. However, the pistol grip was too long for me with the Remington stock
adapter in place. I had trouble reaching the trigger (I typically install a 3/4” spacer on my ARs to lengthen the trigger pull), and my wife could not reach without raising her grip considerably. The comb height was perfect, and that is also adjustable with a set screw. I can only recommend this for shooters with large or long hands. On a Mossberg 500, no adapter is needed. The grip length was much better and comfortable for my hands. The balance was excellent, and shooting comfortable.
The smooth black plastic matches most blue or phosphate finishes and looks very professional. – SurvivalBlog Editor at Large Michael Z. Williamson, author of the new science fiction novel Do Unto Others
