Proof Research AR Style Barrel 223 Wylde 20 Rifle Length Gas 1 7 Twist Stainless

The Proof Research 100462 AR-Style Barrel, crafted in stainless stainless, is designed to elevate AR-platform performance with a 20" rifle length gas system, 1:7" twist, 4 grooves, and 1/2"-28 tpi, in a 223 Wylde configuration to smoothly bridge 5.56mm and .223 cartridges. Built around Proof's Caliber Matched Gas System (CAMGAS), this barrel tunes the gas port location to the cartridge and barrel length, maintaining gas-system pressures near the original AR design while accommodating higher performance rounds. The result is a noticeably softer recoil impulse, reduced fouling in the receiver, improved reliability of extraction, and less wear on brass, enabling steadier follow-up shots and extended shooting sessions. This barrel is well suited for shooters pursuing modern high-performance cartridges such as the 22 Nosler or 6.5 Creedmoor, where bore pressure can remain elevated deeper into the barrel; CAMGAS ensures the AR platform remains on target and dependable as you push for better accuracy and consistency. With Proof Research's emphasis on precision and reliability, this barrel serves as a robust foundation for a precision-built AR rifle that demands consistency, accuracy, and long-term performance.
