The Strike Industries Viper Modular Fixed Stock (brand part no. STRIKEFSFD) combines the adjustability of a collapsible stock with the strength, ergonomics, and solid fit of a true fixed stock. It rides on a standard carbine-length receiver extension and uses an included shim set to dial in length of pull from 12 to 14.25 inches, letting you set it once and get the rigidity of a fixed stock without guessing at fit beforehand. Finished in Flat Dark Earth polymer, it includes a snap hook attachment and sling loop, and it’s built specifically for mil-spec carbine tubes or Strike Industries’ own Advanced Receiver Extension 7-Position buffer tubes.
