Kelbly Pre-Fit Barrels

DESIGNED FOR THE ENTHUSIAST

Kelbly actions provide a headspace guarantee that enables us to design world-class shouldered pre-fit barrels!

Barrels are compatible with the Atlas, Nanook, and Prometheus actions.

Disclaimer:
* All shouldered pre-fit barrels are guaranteed for headspacing.
* We do not guarantee the timing and alignment of the barrel engraving to your stock line.
* Barrels are specific to the action type.
