Blackhawk Knoxx SpecOps Adjustable Stock - Mossberg 500 (Black, K35001-C)

The Blackhawk Knoxx SpecOps adjustable stock for Mossberg 500 shotguns combines recoil management with shooter comfort in a package designed for serious shotgunners. If you've felt the punch of repeated shotgun cycles—whether hunting waterfowl, running clay courses, or training—you know how fatigue and flinch can degrade accuracy and enjoyment. This adjustable stock uses dual recoil-compensation systems to reduce felt recoil, lower muzzle flip, and minimize cheek slap, so you stay behind the gun longer and shoot more confidently.

Built from rugged synthetic materials, the SpecOps stock features six adjustment positions spanning a 12.5" to 15.2" length of pull, making it adaptable to shooters of different frames and clothing layers. The straight cheek weld helps keep your sight picture consistent, while the ergonomic pistol grip is optimized for tactical technique—handy whether you're running a defensive course, hunting in tight cover, or training on the range. A buttstock tensioner removes rattle, and integrated sling-mount points (including a 1" quick-detach swivel) give you flexible carry and shooting options.

Installation is straightforward, and the stock includes a forend with integrated handstop and a multi-position Picatinny-style accessory mount for lights, lasers, or other gear. It also works with receiver-mounted shell carriers if you use them. For a Mossberg 500 owner looking to tame recoil and dial in comfort, this is a practical upgrade that actually delivers on its promise to help you shoot more and hurt less.
