US12516902 - Load balanced firearm barrel extension

A barrel extension configured to reduce the likelihood of premature bolt failure in automatic and/or semi-automatic style weapons. The barrel extension includes one or more cutouts within a body of the barrel extension. The cutouts are configured to reduce rigidity of the barrel extension proximal to the location of the cutout. As the rigidity around the extractor is lowered, the force on the bolt lugs is more evenly distributed. In one example, the cutouts are in the form of a single oval cutout positioned adjacent an extractor of the bolt.
