The Proof Research PR15 PXT carbon fiber AR barrel brings the company's aerospace-grade barrel technology to the 6mm ARC, one of the most capable long-range cartridges ever fitted to the AR-15 platform. Proof wraps a match-grade stainless core in carbon fiber, shedding significant weight while improving heat dissipation, which is why their barrels dominate the precision and mountain-hunting worlds. This 18-inch barrel with a standard .750 gas block journal gives a 6mm ARC build the length to stretch past a thousand yards while keeping the rifle light enough to carry. A premium upgrade for a serious precision gas gun.
