BCM GUNFTR STOCK KIT MOD1 SOPMOD BLK

Description

The BCM GUNFIGHTER Stock Kit Mod 1 SOPMOD is a complete buffer tube assembly built around a widebody stock profile, and it’s aimed at shooters who want a ready-to-run carbine stock system rather than piecing together individual components. Everything needed to complete the lower — receiver extension, carbine buffer, action spring, end plate with quick-detach sling socket, and castle nut — ships together, so there’s no separate sourcing of hardware that has to be confirmed compatible before assembly.

The Mod 1 stock itself is constructed from lightweight polymer and uses a snag-free exterior — no protruding edges, levers, or hardware that can catch a sling, plate carrier, or chest rig during transitions. That matters most in any setup where gear density is high and the rifle has to move quickly through confined positions. The butt pad flips open to reveal a storage compartment in the toe of the stock, sized for small items like batteries or a bolt carrier group tool. The receiver extension is mil-spec diameter, so the stock fits any mil-spec lower on the market without modification.

The widebody SOPMOD profile gives the cheek weld a broader, more consistent surface than a standard carbine stock, which helps repeatable head position across different shooting positions. Because the system ships with the buffer and spring already matched to the extension, there’s no guesswork about stack length or spring pressure — it’s configured to run as a unit from the start.
