Lightweight 6" Barrel on Ruger MK IV Receiver, No Threads

Our Lightweight Carbon Fiber Barrels have evolved.

Inspired by our success with our Lightweight Carbon Fiber Barrels for the 10/22, we've applied these improvements to our new complete Lightweight Upper for the Ruger MK IV.

Each barrel is made from stainless steel and features a laser-hardened breech face for maximum durability even at extreme round counts exceeding 100,000. Our unique design utilizes a woven carbon fiber sleeve for rigidity while still providing an air space between the sleeve and barrel for heat dissipation. This barrel is then threaded into a Ruger MK IV upper receiver.

It's easy to install on any Ruger MK IV lower frame, thanks to its push-button takedown system.
