Fans of the Impact Precision 737 & 787 actions will be an even bigger fan of the PROOF Research Carbon Fiber pre-fit barrels designed for the popular Impact Precision 737R & 787 action. PROOF's Impact pre-fit barrels will arrive threaded/chambered with 5/8x24 muzzle threads. This is a shouldered barrel that requires few specialized tools for install. They're offered with a variety of caliber, lengths, and twist rates in Carbon Fiber.

* These Proof Research/Impact Precision 737R pre-fit barrels are pre-headspaced. However, it is always recommend to double check headspacing with proper gauges before firing a rifle.

    Proof Research Carbon Fiber barrel

    Posted by George on Jan 26th 2021

    the first thing that impressed me about this barrel was the weight. 2.2lbs. I'm used to shooting something the barrel weighs in excess of 6lbs. After some initial rounds to break it in, (not sure it needs that) I proceeded to start testing and developing a load. The barrel seems to be very accutate no matter what i'm shooting so far. I plan on using this in a gun i built for NRL Hunter. While it isn't my first Proof barrel, it is my first carbon fiber and from shooting it, won't be my last. Also kudoo's to Altus, as always a great compnay to work with. This barrel was shipped out to me the same day i ordered it and arrived 2 days later. Thanks
