The BCM Gunfighter Stock Kit Mod 2 Widebody (brand part no. GFSKMOD2RMSBLK) in black is a complete, ready-to-install carbine stock package built by Bravo Company Mfg for AR-platform rifles. Rather than just a stock body, this kit bundles the BCM MK2 receiver extension, spring, buffer, end plate, and locking nut so the whole rear-end assembly goes on as a matched set. The widebody Mod 2 profile is shaped to stay snag-free against slings, plate carriers, and other gear while still giving a stable cheek weld in the prone position. It’s optimized for intermediate-length receiver extensions used on MK2, AR10, and A5-pattern builds.
