Featuring 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.
Actual length when measured to flare is 15.0"
Designed to be used with pistol length, carbine length, mid length, or Mil-Spec M16 rifle length gas systems; all with a low profile gas block.
The barrel nut will fit over all mil-spec diameter barrels (max of 1")
Bravo Company MFG, Inc. US Patent 8904691
