American Rifle Co (Nucleus, Mausingfield, Archimedes, CDG) – Fixed Shoulder – Prefit Barrels

American Rifle Company – Prefit Gun Barrels

The American Rifle Company: Nucleus, Mausingfield, Archimedes, and Coup De Grâce 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.

Note: The Coup De Grâce will be cut with the correct breach face (conical or flat) for your chamber per ARC’s specs.

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.
