Product Description

The PROOF RESEARCH PR-15 Steel AR Barrel in 6mm ARC delivers a precision-engineered upgrade for AR-15 platform shooters who demand accuracy and reliability. 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.

Product Highlights

  • Caliber Matched Gas System (CAMGAS): Precisely positions the gas port for optimal pressure with 6mm ARC, delivering softer recoil and more reliable cycling compared to standard barrel configurations.
  • Stainless Steel Construction: Crafted from durable steel with a stainless steel finish for corrosion resistance and long-lasting performance in demanding conditions.
  • 22-Inch Barrel Length: Maximizes the velocity and ballistic potential of the 6mm ARC cartridge, ideal for long-range shooting applications.
  • 5/8-24 Threaded Muzzle: Compatible with a wide range of muzzle devices including suppressors, compensators, and flash hiders.
  • 1:7.5 Twist Rate: Optimized twist rate stabilizes a broad selection of 6mm ARC projectiles for consistent accuracy downrange.
