This Proof Research pre-fit barrel is made for the Q Mini Fix, giving Mini Fix owners a carbon fiber wrapped .223 Remington 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.
The 1:7 twist stabilizes heavy, high-BC .223 bullets, and the 5/8x24 threaded muzzle takes a suppressor or brake. The short barrel keeps the Mini Fix compact and handy, and because it 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.
