Accuracy and Reliability Are Now Attainable

The PROOF Research AR 308 PR-10 barrel provides owners of AR-10-pattern rifles with a 6.5 Creedmoor-chambered rifle that includes a number of enhanced features over traditional barrel styles. These long range specific barrels provide the ultimate in accuracy and will maintain their performance in the harshest of conditions.

The PROOF Research AR 308 PR-10 barrel  uses the company's innovative CamGas system, which works to reduce the speed of the bolt carrier and improve overall function and reliability of 6.5 Creedmoor semi-auto rifles.

  • Provide shooters with enhanced accuracy on par with match-grade guns
  • Better cooling properties provide improved barrel life
  • POI shift does not occur during extended fire strings
  • The proprietary gas tube is included, but requires use of a JP enhanced high pressure bolt for best function. (452-000-113)

The PROOF Research AR 308 PR-10 barrel is cut rifled from double stressed relieved 416R stainless steel and features a threaded muzzle with a 5/8x24 TPI thread pitch for the addition of muzzle accessories.
