The BCM Gunfighter complete lower receiver group with a Mod 1 stock in black (brand part no. LRG-RMS-STK-MOD-1-SPMD-BLK) is an assembled lower from Bravo Company Mfg that pairs the MK2 Recoil Mitigation System with that stock. The BCM Mod 1 has a SOPMOD-style body for a more pronounced cheek weld and a storage cavity in the toe of the stock. The MK2 RMS smooths out buffer travel with a hard coat anodized 7075T6 aluminum buffer and an M16A4 rifle spring in a rifle-length buffer tube. It suits a builder who wants a modern, tuned recoil system and a stock with storage in one assembled lower.
