The Adaptive Tactical EX Performance Adjustable Pistol Grip Stock is a pump shotgun upgrade designed specifically for Mossberg 500, 590, and Maverick 88 12-gauge models. Built from durable high-impact polymer, this modern stock replaces the factory furniture with a tactical profile that improves control, ergonomics, and shooting comfort—whether you're running three-gun matches, home defense drills, or precision shotgun work at the range.
What sets the EX Performance apart is its adjustability. The quick-access length-of-pull adjustment lever lets you customize the stock to your frame and shooting gear in seconds, with a range from 10.5 inches (without pad) to 15 inches (with pad). This is critical if you're wearing heavy winter layers or tactical kit that changes your measurement season to season. The integrated QD swivel attachment and molded sling point give you mounting options without drilling, and the vented rubber recoil pad reduces felt impulse during extended shooting sessions.
Installation is straightforward—Adaptive Tactical engineered this for owner-level work with a covered takedown pin that makes removal and reinstallation simple. The non-slip vented recoil pad and oversized adjustment pin are built to handle the rigors of regular use, and the sleek industrial design won't look out of place on a hunting or tactical shotgun. Made in the U.S.A.
One important note: this stock is not compatible with Mossberg Shockwave or TAC-14 models, as it creates a short-barreled configuration on those firearms.
