Rainier Arms

Rainier makes great UltraMatch bbls. They might not be the cheapest, but they have a real pursuit of making one of the finest barrels on the market made from high-quality blanks. I have a couple of their barrels in 5.56 and 6.5 Grendel. Both barrels were really high quality. I am in the process of building a 6.5 Gren pistol with a 12.5" barrel and will probably go through them for the barrel again. The Ultramatch with the TiN gold end usually only comes on their premium barrels. They have a 90 day unlimited round return policy, so you can get it and put it through the paces before you decide to keep it. The fact they allow that type of guarantee you have to be building quality barrels or you'd be out of business by now. I've even heard of someone who was able to return one after using one for a year. You won't find any other company willing to do that. They are good people that are focused on good customer service.
