PROOF RESEARCH Intermediate AR-Type Barrel 6mm ARC 14.50"

Our AR barrels are designed to enhance both performance and reliability within the AR platform. Featuring the Caliber Matched Gas system (CAMGAS), the gas system is precisely tuned to match the specific cartridge and barrel length. Traditionally, the AR-15 platform was optimized for the .223 Remington and 5.56x45mm cartridges, while the AR-10 was tailored for the .308 Win/7.62 NATO rounds. With the introduction of high-performance cartridges like the 6.5 Creedmoor, bore pressure remains elevated further along the barrel. By strategically relocating the gas port, the design ensures that the gas system pressure aligns with the original specifications of the AR platforms. This innovation results in a significantly softer recoil impulse, reduced fouling in the receiver, enhanced extraction reliability and minimized wear on brass. These improvements help maintain focus on the target and allow full utilization of the benefits of cutting-edge high-performance cartridges.The barrels are guaranteed to meet the head spacing specifications of the JP Enterprise enhanced boltVerify and confirm adequate headspace prior to discharging your rifleIt is recommended to utilize full mass components, including the full mass bolt, buffer and springs, throughout the systemAll barrels equipped with intermediate, rifle +1, rifle +2 and rifle +3 gas systems are supplied with the appropriate gas tubeThe AR-10 barrels we offer incorporate a deep feed system, ensuring compatibility of the feed ramps with those in the lower receivers of both DPMS and Armalite-style riflesUp to 64% lighter compared to traditional steel barrels with a similar contourEnhanced thermal resistance - optimized heat dissipation for cooler and more durable barrelsThe product exhibits exceptional durability, being encased in high-strength, aerospace-grade carbon fiber that is infused with a proprietary matrix resin1:7.5 barrel twist ratePort size - 0.082 inches3/4 inches gas journal
