About McGowen

Formed in 2007, McGowen Precision Barrels builds on a proud tradition of custom barrel manufacturing.  McGowen Precision Barrels was started with the purchase of Harry McGowen’s “mothballed” machinery.  The  manufacturing process has been updated to 21st Century techniques. Using state of the art equipment, and finely honed manufacturing techniques, McGowen Precision Barrels aims to make the highest quality barrels on the market. The manufacturing process continues to undergo changes and improvements in the pursuit of perfection.  The McGowen Precision Barrels name is making an impact in the industry, not only in hunting rifles, but are now becoming a favorite of long range competition shooters.

 

Cut Rifling

We are in the process of perfecting the age old tradition of cut rifling. We are working on cut barrels with the highest degree of accuracy manufactured with 21st Century digital perfection. Currently, we are able to produce 6.5 caliber, 30 caliber, and 338 caliber cut-rifled barrels. We do not have an anticipated date in which more calibers will be available.

Future Projects & Growth

McGowen Precision Barrels will continue to upgrade our machinery and our capabilities. We’re also working hand-in-hand with our sister company McGowen Gun Works to manufacture custom rifle actions. We are currently working on the final design on our patented Mini action. Keep watching here and our sister companies website americangunco.com for more information.
