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.

4 star couse nothing is perfect. Review by
The barrel is a spot on match barrel, very nice . Chamber is tight so clean and lube frequently. I run suppressed so it gets dirty pretty fast. Less than 200 rd threw it and it shot 1.5" groups at 400 yards with 175 GMM . Hope it will get better but my opinion is its a great barrel as is. (Posted on 3/5/2017)
