The BCM Mod 2 SOPMOD Widebody Stock (brand part number BCM-GFS-MOD2-SPMD-BLK) improves on the baseline M4 stock with a patented semi-clubfoot design (US Patent D901616) that boosts both ergonomics and durability. It’s built for Mil-Spec carbine receiver extensions and optimized for intermediate-length tubes like the MK2, AR10, and A5. Bravo Company Mfg reshaped the lines to stay snag-free in the prone position, so there’s nothing to catch on a sling, antenna, or your gear. It retains BCM’s patented internal latch system and ambidextrous, rotation-limited QD interface, while adding an end-user removable buttpad, an improved VBOST sling retention point, and two additional web sling attachment slots.
