***Rainier Arms Ultramatch 20" Bull Contour Fluted***

We wanted to build an .308 barrel using the finest blank and mass produce them to bring them to market at the most competitive prices. Our UltraMatch barrels start out as Shilen blanks and contoured to our specifications. We wanted the best balance between accuracy while keeping the weight down as much as possible. The Rainier Match Chamber is a modified .308 WIN-7.62 NATO chamber to produce ultimate reliability and accuracy shooting both the 7.62 NATO & .308 WIN rounds.

Why would you review a product that you don't even own. A friend has one? Thanks bud! (Posted on 7/2/2016)
.5 MOAReview by
Friend has this one. Build: Mega AR-10 upper/lower. Geissle SD-E, Leopold 3-18x44 with Horus. Sandman-L can. Atlas bipod front, bag rear.

100yrds light wind .5MOA over and over with factory Federal 168 SMK's. .7MOA with the 175's but I'd bet 1000.00 that the 175's hold tighter at 500yrds

Highly accurate awesome barrelReview by
This barrel is everything I could ask for and more! This barrel is shooting .5 MOA all day with groups much smaller than that and I am by no means an expert shooter. If you want quality combined with the highest accuracy then buy this barrel! It fit my dpms receiver with no issues. (Posted on 4/15/2015)
