Product Overview

Features

  • Match-grade accuracy
  • Unprecedented durability
  • Double-stress relieved 416R stainless steel
  • CAMGAS system improves reliability while smoothing operation and recoil impulse

 

Proof Research's steel barrels are produced in-house from double-stress relieved 416R stainless steel. This pre-hardened chromium steel is ideally suited for match grade rifle barrels. Each barrel is drilled, contoured and reamed to bore diameter. It is then cut rifled, lapped, and inspected via borescope. This ensures an extremely consistent and accurate finished product.

 

Proof’s Caliber Matched Gas System (CAMGAS) barrels eliminate the issues traditionally associated with building 6.5mm and .260 rifles on 308AR/AR-10 platforms. Until now, AR-variant shooters looking for ballistic advantages from either of these calibers were faced with excessive bore pressures that necessitated makeshift solutions such as clipping buffer springs, adjusting buffer weights, and/or relying on adjustable gas blocks, to keep their rifles functioning properly.

 

Proof’s R&D team solved the overpressure issue with gas systems tuned specifically to the cartridge/barrel-length combination. By moving the gas port, the pressure in the bore is given time to reduce to that comparable of a .308 Winchester with a rifle-length gas system, which is what the 308AR/AR-10 system was designed around. The recoil impulse is noticeably smoother, which helps keep you on target while taking advantage of a more efficient projectile. Case extraction is also easier, with less case-head smearing, so the brass is in much better condition for reloading.
