PROOF Research AR-15 20" Rifle+1-Length Gas 6mm ARC 1:7.5 Carbon Fiber Wrapped-Barrel

Spice up your next rifle build and enjoy pin-point precision accuracy with the PROOF Research AR-15 20" Rifle+1-Length Gas 6mm ARC 1:7.5 Carbon Fiber-Wrapped Barrel. Featuring a match-grade, thin-contoured 416R stainless steel design with a featherweight carbon fiber wrap, this ultralightweight rifle barrel is up to 64% lighter than traditional steel barrels of similar contour. 416R stainless steel construction offers exceptional strength, reliability, and lasting corrosion resistance, while the aircraft-grade carbon-fiber wrap is impregnated with a proprietary matrix resin composite for improved heat dissipation, optimal strength, and reduced overall weight without sacrificing reliability or affecting accuracy. The rifle+1-length gas system maximizes reliability with most match-grade target loads for safe operation under higher pressures. Plus, this performance-enhanced AR-15 rifle barrel comes threaded from the factory with 1/2x28 threads for quick installation of a variety of flash hiders, brakes, and other muzzle devices right out of the box. Made in USA.
