Proof Research Pre-Fit Q Fix Barrel Features The Proof Research Q Fix barrel wraps a stainless steel core in carbon fiber cutting significant weight compared to a traditional steel barrel while retaining the rigidity needed for match-grade accuracy. At just 2 pounds this 16 inch barrel is far lighter than a comparable all-steel option making it easier to carry on long hunts or precision matches. The 1-in-10 twist rate is well suited to stabilizing a broad range of .308 Win bullet weights used in both hunting and precision shooting. Because it is a pre-fit design the barrel is intended as a direct drop-in replacement for compatible actions simplifying installation for shooters upgrading their rifle s accuracy potential. The 5/8x24 threaded muzzle accepts a suppressor or muzzle brake giving shooters flexibility to manage recoil and report. Proof Research s reputation for match-grade carbon fiber-wrapped barrels makes this a strong option for shooters seeking a lightweight accuracy upgrade available for sale at GrabAGun.
