Rainier Arms Select Dissipator 5.56 NATO 16" AR-15 Barrel

Many have asked us to build a barrel with the same workmanship as our Match barrels while keeping it more affordable. We are able to reach our goal by sourcing a very high end barrel blank at an affordable price. We start off using a high precision match blank in 1:8 twist, use a 5 groove polygonal rifling, machine it to the highest quality and matched with our limited-life time warranty, you have a barrel that is the best value, hands down, in the industry.
