The Proof Research 152195 PR15 6 ARC 20 7.5TW PXT barrel is a premium upgrade for shooters who demand precision and reduced weight from their AR-platform rifles. Featuring Proof Research’s signature carbon fiber–wrapped design over a stainless steel core, this extra barrel is engineered to deliver excellent rigidity and heat management while trimming ounces from the front of the rifle.

This model is purpose-built as a firearm accessory barrel for the 6 ARC cartridge, offering a 20-inch profile with a fast 1:7.5 twist rate to stabilize a wide range of modern projectiles. The threaded muzzle makes it ready for compatible brakes or suppressor mounts, and the carbon fiber construction helps maintain balance for extended range sessions or field use. It is an ideal choice for precision-focused shooters who want a lighter, more controllable rifle without sacrificing accuracy, reflecting Proof Research’s reputation for innovation in advanced barrel technology.
