The BCM Gunfighter Stock Kit Mod 2 Widebody (brand part no. BCM-GFSK-MOD2-RMS-FDE) in flat dark earth is a complete, ready-to-install carbine stock package from Bravo Company Mfg for AR-platform rifles. Instead of sourcing a stock, tube, buffer, and spring separately, this kit bundles the BCM MK2 receiver extension, action spring, buffer, end plate, and locking nut into one matched set. The widebody Mod 2 profile is shaped to stay snag-free against slings and gear while holding a stable cheek weld from the prone position. It’s built around an intermediate-length receiver extension suited to MK2, AR10, and A5-pattern builds, and it matches FDE-finished uppers and lowers.
