Nucleus+Mausingfield (fixed shoulder) 1.055xa20x680

Base Price: $400

The Nucleus/Mausingfield/Archimedes actions from American Rifle Company 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. So simple as that you are ready to go to the range and start shooting ragged hole groups again with your Preferred barrel cut to the length, contour, and chamber of your choice.
