Fans of the Impact Precision 737R actions will be an even bigger fan of the PROOF Research pre-fit stainless steel designed for the popular Impact Precision 737R action.

They're offered with a variety of caliber, lengths, and twist rates in stainless steel..
* 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.
Decided to give it a try. At the price point it was worth testing. This barrel is lights out right from the box. I bought 2 more! This is my second year in NRL and this barrel is a gamechanger.
This barrel absolutely hammers. Sub 0.3MOA right out of the box, with my best groups at 0.1MOA with Berger 109s. These will be my go to barrels from here on out.
6 Creedmor Impact 737R Prefit
Super pleased with this setup for my PRS rifle. It hammers. After Break In I am getting 0.3" groups, and I dont know that I can hold any better than that. I would definitely recommend to anyone interested in a super accurate rifle.
Great barrel, would/will buy again
I got the 26" 6.5CM in Comp. Contour. Puts the balance point just in front of the magwell (MPA Comp chassis w/ bag rider, 1 front MPA weight, 737 action, and Razor scope). It clears the MPA chassis, but it definitely fills it up. If your using anything else I would measure twice. We'll see how it holds up over this next year, but right now, it looks like I'll be buying another when I burn this one out.
