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.
- MCMR features M-LOK® Compatible mounting system.
- Free Float Handguard eliminates loads from barrel, reducing the deflection for more accurate shooting.
- Precision Machined Aerospace 6061-T6 Aluminum Alloy, for high strength and lightweight.
- Proprietary engineered profile offers additional cross sectional strength.
- Steel Barrel Nut (same KMR, MCMR, and QRF series), to resist movement under heat.
