Bravo Company's BCM MCMR-13 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 13.4 inches and is designed to be used with pistol
length, carbine length, mid length or rifle length gas systems; all with
a low profile gas block.
