Featuring the same industry leading barrel nut and lock up design introduced on BCM’s KMR handguard, the MCMR series of handguards delivers modularity for the M-LOK platform. Its proprietary patented mounting system (US Patent 8904691), includes a mechanical index to the 12-o’clock rail and positions mounting hardware to mitigate movement caused by heat. So you can rest assured that your rail will stay securely in place, even under heavy use. Plus, with its 10.5″ length, you’ll have plenty of room to attach all your favorite accessories.
