The Commando Mark III isn't too bad at resembling a Tommy gun - from a distance. And the closer you look, the more you notice that while Thompsons are well-built machines, this one just isn't. I was having some feed problems and then the barrel started wiggling around in the receiver. Yikes! Here's what I did to correct the problem. This may not be the end-all solution for the feed ramp, but it sure did stabilize the barrel and make the gun safe to fire.
