Mack Brothers – Fixed Shoulder – Prefit Barrels

Mack Brothers – Prefit Gun Barrels

The Mack Brother’s Evo actions are extremely repeatable, so nice in fact, we are able to offer prefit barrels for their actions configured in a shouldered barrel. This means there is no barrel nut to worry about, with the use of a barrel vise you can spin off an old shot-out barrel and ours will thread directly back on and headspace correctly to your bolt.

Please note: While we are responsible for making you a quality product, You are liable for how this product is ordered. It is your responsibility to verify the head spacing and breech specs beforehand; we do not refund incorrectly, custom-ordered products. Any changes to orders must be made within 48 hours of order placement. Thank you and Happy Shooting!

The current estimated build time is 10-12 weeks or longer.
