PROOF Research AR-15 18" Carbon Fiber Barrel 223 Wylde 1:7 Rifle-Length Gas

Compatible with most rifle-length gas systems, the PROOF Research AR-15 18" Rifle-Length Gas .223 Wylde 1:7 Carbon Fiber-Wrapped Barrel is a performance-enhanced AR-15 replacement rifle, designed to deliver exceptional accuracy and superior longevity over standard steel barrels. Favored by experienced shooters across the globe, this barrel is up to 64% lighter than traditional steel barrels of similar contour. The match-grade 416R stainless steel barrel offers exceptional strength and reliability, while the slim contour reduces the barrel's overall weight without sacrificing reliability. The aircraft-grade carbon fiber wrap is impregnated with a proprietary matrix resin composite for improved strength, lasting service life, and improved heat dissipation, allowing the barrel to cool faster and maintain accuracy. To top it off, this PROOF Research AR-15 rifle barrel comes threaded from the factory with 5/8x24 threads for quick installation of a variety of flash hiders, brakes, and other muzzle devices. Made in USA.
