The BLACKHAWK! Knoxx SpecOps Stock is designed to fit any size operator with more than 4 inches of adjustment. Utilizing the dual Knoxx recoil compensating systems, the SpecOps Stock reduces perceived felt recoil up to 95 percent; including the recoil of the heaviest loads. The SpecOps adjustable length-of-pull style stock allows law enforcement and military personnel to use shotguns with all load-bearing and ballistic tactical vests. The SpecOps Stock eliminates shoulder fatigue and by cutting muzzle rise, allows the operator to get back on the target faster. the SpecOps fits the Remington 870, Mossberg 500/590/835 Maverick 88, and Winchester 1300 series 20- and 12-gauge pump shotguns.
