Description
The Aim Sports APGSM500 is a drop-in pistol grip and collapsible buttstock kit designed to upgrade your 12 Gauge Mossberg 500, 500A, or 590 pump shotgun. Building on the proven Mossberg 500 platform, this aftermarket set replaces the factory fixed stock with an M4-style adjustable assembly that gives any shooter a better fit, faster shouldering, and a more tactical handling profile.
The buttstock adjusts through 6 positions for length of pull, so it can be tuned to different shooters, body armor, or shooting stances on the fly. A black polymer over aluminum construction keeps the kit lightweight while staying tough enough for hard use, and the ergonomic pistol grip is shaped to sit naturally in the hand. The grip also houses internal storage for small tools or spares, and an ambidextrous sling loop is built in so the stock can be run with single-point or conventional sling setups without extra hardware.
Installation is straightforward and requires no permanent modification to the receiver – the unit drops in place of the original Mossberg stock and grip hardware. A buffer tube is included, so the kit is ready to mount right out of the package. Whether you are running a tactical home-defense shotgun or simply want a more adjustable fit on a sporting 500, the APGSM500 is a clean, affordable way to modernize the platform.
