Highly Weethl HMG: Barrel Converter

A free heavy machine gun for those in need. Now with a shorter barrel, legally distinct muzzle breaks, and an opening that should be able to press fit over any 3x1mm barrel/magnet. Feel free to add glue if you'd like. I've included a short variant with space for some 2x1mm magnets to fit between the barrel and the back. I hope this helps anyone in need.
