This Proof Research pre-fit barrel is made for the Q Mini Fix, giving Mini Fix owners a 12.75" carbon fiber wrapped .300 Blackout barrel from one of the best-known names in precision barrels. A pre-fit barrel is chambered for its specific action, so it arrives ready to install on the Mini Fix.

.300 Blackout is at its best in short barrels, and at 12.75" this barrel keeps the Mini Fix compact behind a suppressor while running supersonic loads for range work and subsonic loads for quiet shooting. Because the barrel is under 16.00", fitting it to a Mini Fix with a stock makes the rifle a short barrel rifle, so the NFA paperwork needs to be in place first.
