Handguard: 1.7" internal diameter at its narrowest point.īarrel Nut: 1.05" internal diameter at its narrowest point. Hard Coat Anodized per Mil-A-8625F, Type III, Class 2ĭesigned to be used with Mil-Spec M16 rifle length gas systems with FSB or low profile gas block, or mid length and carbine gas systems with a low profile gas block.Dimensions: 10.03"(Length) * 2.43"(Height) * 2.43"(Width). Steel Barrel Nut (same KMR, MCMR, and QRF series), to resist movement under heat.
Includes 4 QD Sing Swivel Sockets, (limited rotation) Proprietary engineered profile offers additional cross sectional strength.
Precision Machined Aerospace 6061-T6 Aluminum Alloy, for high strength and lightweight. 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.įree Float Quad Rail eliminates loads from barrel, reducing the deflection for more accurate shooting. Featuring the same industry leading barrel nut and lock up design as originally introduced on BCM's evolutionary KMR handguard, the QRF Series of handguards gives the shooter modularity in the picatinny (MIL-STD-1913) platform.
