Excellent barrelReview by
I build custom Ar10 platform rifles. You really should add and match a bolt to the barrel. I have struggled through functioning issues and I know what I am doing. The receiver extension looked a little ragged from the get go. I had to file and trim the bolt and RE to improve functioning. Superbly accurate barrel. I hit the the 1000 yard gone on the third shot. Absolutely no copper build up from the get go. Great product close but not perfect.. (Posted on 12/5/2016)

I bought this for a build and it is the quality I have come to expect from Shilen and Rainier. I appreciate the addition of the gas tube. My only complaint is that, because this is a match grade barrel marketed for an AR-10 rifle, that the barrel does not come with a head-spaced bolt. This would not typically be an issue for a 5.56mm AR-15 because industry tolerances are so strict. However, an AR-10 platform is far less forgiving and I would gladly pay extra for a barrel that included a match grade bolt that is properly headspaced. (Posted on 10/5/2016)
WINNER!!!!Review by
The 6.5 Creedmoor Ultra-Match is a star! After completing my Maten build and some barrel break in, the ultra-match has been printing .5 inch or better groups at 100yrds! I have about 80 rounds of Hornady 140gr match ammo through the rifle with great results. Thanks Rainier for a great product! Will be looking to purchase another as soon as back in-stock!

Great BarrelReview by
This is a beautiful, high quality product. I just bought one for a long range AR10 project. After a quick install and light break in, we were able to shoot a 5 shot group at 100 yards that was under 1/2 inch. So far I've only shot it with Prime 130 grain factory match ammo, but it is definitely a great barrel. (Posted on 3/26/2016)
