BCM Gunfighter Mod 0 Kit in Flat Dark Earth for AR-Platform - Includes Stock Tube

The BCM Gunfighter Mod 0 Kit in Flat Dark Earth gives you everything needed to complete an AR-platform build or refresh with quality, mil-spec components. Bravo Company's Gunfighter line is trusted by shooters who demand reliability over hype, and this kit bundles the essentials—stock, tube, buffer system, and hardware—so you're not hunting down five different part numbers. Whether you're building your first AR or upgrading an existing lower receiver, this kit covers the back end with proven designs.

The Gunfighter Mod 0 Stock is known for its ergonomic design and solid lock-up. The kit ships with a 7075 T6 mil-spec receiver extension (stock tube), mil-spec carbine action spring, carbine buffer, castle nut, and QD swivel mount receiver end plate. All the parts are compatible with standard AR-platform lowers, so compatibility issues are off the table. The Flat Dark Earth finish matches modern AR builds and offers a neutral, professional look that works in field or tactical setups.

Building or maintaining an AR doesn't have to mean piecing together budget components or overpaying for mall-ninja hype. The Gunfighter Mod 0 Kit delivers mid-range quality at a fair value—the kind of stuff that works when you need it and doesn't demand babying. If you're tired of wobbling stocks and creeping receiver extensions, this kit addresses both.
