I really enjoy the Lewis Gun, and it's been a long time since I had a chance to put some rounds through one. This particular example is a Savage-made gun marked USN, and I think (but can't prove) that it is one of a small number purchased in .303 British caliber for the US Marine Corps. It also has the heavy-duty bipod system used by the Marines, which I have never tried before. So, let's give it a try!
