We are so confident in our barrels that we offer a 100% money back guarantee within 90 days of purchase. If our barrels don’t meet or exceed your expectations, for any reason, return it for a full refund.
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 1:7 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.

Our Craftsmanship
Rainier barrels are meticulously designed and machined by precision gunsmiths. Our barrels are turned the same way true artisans have made premium rifle barrels for over a century. Each barrel has hand-cut chambers and crowns with the attention to detail that can only come from highly trained human intervention. While most companies strive for faster production time to cut costs, we strive for perfection. There are no shortcuts with our barrels, period.
