Tacticool22 Specializes in aftermarket Smith & Wesson M&PA(R) 15-22 parts and the Tailhook extractor is one such part. Made from non-rusting knife steel through a wire EDM process and heat treated for an extractor that keeps an edge over countless rounds. This M&PA(R) 15-22 extractor has also been designed with extra clearance to prevent build-up .22LR ammo, which reduces overall effectiveness. The Tailhook Extractor works will in conjunction with Tacticool22's Extractor Plunger, and Extractor Spring, both sold separately. Mfg: Tacticool22
