Bravo Company's BCM MCMR-9 M-LOK Compatible Modular Rail Handguard features the same industry leading barrel nut and lock up design as originally introduced on BCM's evolutionary KMR handguard. The MCMR Series of handguards gives the shooter modularity in the M-LOK platform. This proprietary patented mounting system (US Patent 8904691) includes a mechanical index to the 12:00 rail and positions mounting hardware to mitigate the movement caused by heat generated by the weapon system. It is made from Precision Machined Aerospace 6061-T6 Aluminum Alloy for high strength and is lightweight. The proprietary engineered profile offers additional cross sectional strength. The actual length when measured to flare is 9.4 inches and is designed to be used with pistol length, carbine length, or mid length gas systems; all with a low profile gas block.
