Douglas Barrels

Douglas Barrels has been the G.R. Douglas name since 1948—over seven decades of ultra-rifled precision. They manufacture American-made custom rifle barrels using carbide push-button rifling, high-quality 416R Stainless Steel or 4140 Chrome Moly, and traditional craftsmanship combined with modern machining technology.

Ultra-rifled precision is their signature. Barrels are air-gauge tested to show as little as .0001" variance from desired finish caliber. This level of consistency separates Douglas from competitors and earned them the "ultra-rifled" designation.

"For over seventy-five years, the G.R. Douglas stamp marking an American-made ultra-rifled gun barrel has remained a clear indication of premium quality, unmatched precision, and pinpoint accuracy."
