Product Description

The Proof Research PR15 6mm ARC Stainless Steel Threaded Barrel delivers precision-engineered performance for AR-15 platform rifles. Constructed from premium chromium stainless steel, this 14.5-inch barrel is chambered in the increasingly popular 6mm ARC cartridge and features a 1:7.5 twist rate that ensures exceptional accuracy and projectile stability across a wide range of bullet weights. The muzzle is threaded 5/8x24 for easy suppressor or muzzle device attachment, while the .750-inch gas block journal accommodates a standard low-profile gas block. A Nickel-Ion finish provides outstanding corrosion resistance, protecting the barrel through extended field use and harsh conditions. The intermediate-length gas system is optimally tuned to reduce felt recoil and improve cycling reliability, making this barrel a top-tier upgrade for competitive shooters and tactical enthusiasts alike.

  • 5/8x24 Threaded Muzzle - Industry-standard threading allows easy attachment of suppressors, muzzle brakes, and flash hiders.
  • Intermediate Gas System with .750 in Gas Block Journal - Reduces recoil and improves reliability, compatible with standard AR-15 low-profile gas blocks.
