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.

Features:

• 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.
• Hard Coat Anodized per Mil-A-8625F, Type III, Class 2
• Handguard alone weighs:
  • 7": 4.8 oz
  • 10": 6.6 oz
  • 13": 8.2 oz
  • 15": 9.2 oz
• Handguard mounting hardware 2.3 oz
• 1.3” Inside Diameter
• 1.5" Wide

Designed to be used with mid length with a FSB or a carbine gas system with a low profile gas block.

The barrel nut will fit over all mil-spec diameter barrels (max of 1")
