Proof Research Carbon Fiber 22 Nosler AR Barrel
Upgrade to match-grade accuracy, superior durability and increased barrel life at a fraction of the weight of steel barrels with Proof Research's Carbon-Fiber 22 Nosler AR Barrel. Using 416 R stainless steel, advanced composite materials and thermo-mechanical design principles, it is up to 50% lighter and cools up to 60% faster than stainless steel barrels of similar contour, resulting in unparalleled match-grade accuracy. Patent-pending Caliber Matched Gas System (CAMGAS) barrels eliminate overpressure issues by shifting the gas port, allowing extra time to reduce pressure – similar to a .308 Winchester with a rifle-length gas system. Forget about using makeshift solutions like clipping buffer springs, adjusting buffer weights or relying on adjustable gas blocks to overcome excessive bore pressure. Delivering a smoother recoil impulse, a CAMGAS-equipped barrel keeps you on target while taking advantage of a more efficient projectile. It also ensures easy case extraction with less case-head smearing to keep brass in optimal condition for reloading.
