Made by Americans in Hartland, WI – the BCM Mod 2 stock is an improvement over the baseline M4 accessory with enhanced ergonomics, and next-level durability. Recontoured into a patented (United States Patent Number: D901616) semi-clubfoot design, the Mod 2 is fits on Mil-Spec carbine receiver extensions, and optimized for intermediate length receiver extensions (MK2, AR10, A5). These improved lines also enhance shooting in the prone position while remaining snag free, with no edges to catch or tangle in slings, antenna, or other PPE
