Why Choose the Strike Industries Modular Fixed Stock

Traditional fixed stocks lack flexibility, while standard collapsible options can feel less stable under heavy recoil. This stock solves both pain points by providing fixed-stock ergonomics with precise LOP tuning via shims, promoting better shoulder fit, reduced fatigue, and improved shot consistency. Its polymer-over-steel design balances minimal weight with exceptional durability for competitive, defensive, or recreational use.

Note: Requires a standard mil-spec castle nut, buffer tube, and endplate for installation. Compatible with A5-length carbine extensions.

Installation and Adjustment

Installation is straightforward for users familiar with AR-15 lower receiver components. Stack or remove the provided shims behind the stock to dial in your preferred length of pull, then secure with the included hardware for a locked-in, professional-grade setup.
