Simply tighten the barrel nut to 65 ft lbs, slide the handguard over until it is flush with upper receiver. The inside diameter is 1.310' and uses a non-proprietary barrel nut that does not require timing.

GGP AR-15 handguards are extruded from 6061-T6 Aircraft Grade Aluminum, finished with True Black Type III Class 2 Hard Coat Anodizing and are available in 7.25', 9.25', 12.625', 15' and 17' lengths. For more information, go to our tried and true handguard design that comes standard on all GGP MKII rifles is available for the builders out there. WARNING: This product can expose you to chemicals including Cumene and Titanium Dioxide, which is known to the State of California to cause cancer. The barrel nut will fit over all mil-spec diameter barrels (max of 1')īravo Company MFG, Inc. Hard Coat Anodized per Mil-A-8625F, Type III, Class 2ĭesigned to be used with mid length and carbine gas systems with a low profile gas block.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.

Free Float Quad Rail eliminates loads from barrel, reducing the deflection for more accurate shooting.

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. Includes T, L, R, and B recoil slot markings on all four rails to aid in repeatable set up for the end user. BCM® QRF-10 (Quad Rail Free Float Handguard)įeaturing 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.
