6 dasher prefit
These barrels are so great. They’ve made a high quality barrel at a great price, this is my third barrel in Dasher and they all shoot light out. Will continue to use and order more in the future.

737R Dasher prefit
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.

Impact Proof 6 Creedmoor
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.
