Consistent accuracy so farReview by
I've done load work ups with 69 and 77 grain bullets so far. Accuracy is very consistent regardless of the load. It puts 5 77 grain MatchKings under an inch with a max charge of Varget and makes 2860 ft/s. The finish looks great, the threads fit fine. Exactly what I was hoping for. I called Rock Creek with a question about break-in, and they were helpful. (Posted on 8/27/2016)
Very AccurateReview by
The gas block seat was very tight, but I was able to install a BCM low profile gas block. Everything else on the barrel is perfect. This is definitely a great value for a very accurate barrel! (Posted on 2/29/2016)
Rainer has great customer serviceReview by
I also received this barrel with the muzzle threads cut large. The threads were damaged when test fitting the brake and Rainer replaced the barrel and brake. Thanks for the help Rainier! (Posted on 2/11/2016)
Gunsmith had bad day.Review by
First barrel had the muzzle threads cut at ".505" maximum is ".498"

Replacement barrel was the exact same @ ".505" Had to purchase a threading die and thread the muzzle myself....After threading it, it is now the proper ".498" dead on.

Also the gas block measurement was .752 Making installing a dimpled gas block a difficult endeavor, luckily I have a lathe.

Rainier arms made it right and I thank them for that.

Mike Rock knows how to spin a barrel and this one is no exception.

Whoever is turning these barrels needs to pay more attention though.
