Built from stainless steel and engineered around PROOF Research's proprietary Caliber Matched Gas System (CAMGAS), this 22-inch threaded barrel is purpose-built to maximize the performance potential of the 6mm ARC cartridge. CAMGAS technology repositions the gas port to ensure the operating pressure at the port matches exactly what the AR-15 platform was originally designed for, resulting in a noticeably softer recoil impulse, reduced fouling in the receiver, improved extraction reliability, and less wear on brass. Whether you're a precision competitor or a long-range hunter, this barrel offers a high-performance solution that takes full advantage of modern cartridge technology without compromising the function of your AR-15.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCaliber Matched Gas System (CAMGAS):\u003c\/strong\u003e Precisely positions the gas port for optimal pressure with 6mm ARC, delivering softer recoil and more reliable cycling compared to standard barrel configurations.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStainless Steel Construction:\u003c\/strong\u003e Crafted from durable steel with a stainless steel finish for corrosion resistance and long-lasting performance in demanding conditions.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e22-Inch Barrel Length:\u003c\/strong\u003e Maximizes the velocity and ballistic potential of the 6mm ARC cartridge, ideal for long-range shooting applications.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e5\/8-24 Threaded Muzzle:\u003c\/strong\u003e Compatible with a wide range of muzzle devices including suppressors, compensators, and flash hiders.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e1:7.5 Twist Rate:\u003c\/strong\u003e Optimized twist rate stabilizes a broad selection of 6mm ARC projectiles for consistent accuracy downrange.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecs\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e PROOF RESEARCH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number (MPN):\u003c\/strong\u003e 143674\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 843068143674\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCaliber:\u003c\/strong\u003e 6mm ARC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Length:\u003c\/strong\u003e 22 in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTwist Rate:\u003c\/strong\u003e 1:7.5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMuzzle Thread:\u003c\/strong\u003e 5\/8-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas System Length:\u003c\/strong\u003e Rifle +1 Length\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas Block Journal Diameter:\u003c\/strong\u003e .750 in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas Block Journal Length:\u003c\/strong\u003e 1 in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Color:\u003c\/strong\u003e Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFluted:\u003c\/strong\u003e No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlatform Compatibility:\u003c\/strong\u003e AR-15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 2.15 lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGun Type:\u003c\/strong\u003e Rifle\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cem\u003eDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
