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.
We will go toe to toe with anyone and win.
