  1. Thank you for your response, I am thinking that it is likely a recoil issue. There isn't any packing. When I got the gun it had been painted with black spray paint, pretty thick. I stripped it and hot blued it. So I am assuming any packing material that may have been there would have been removed by either the paint stripper or the actone it was soaked in. The booster is a repro made by Adco, from what I can tell its made exactly like the original. I took the booster off yesterday and did a pogo test like on an MG42 and it seem a little ruff. I opend the cover and checked it after firing it several times and the lock appeared to be at the top of the stroke, the fuzzee was set to 20 during test firing. I ordered a copy of The Devil's Paintbrush yesterday. I am going to try and disassemble it and see if I can't get the barrel assembly moving more freely before I test fire it again.

  2. You nailed that is what the problem was. I guess one of my dumbass employees must have dropped it because the end of the shroud was buggered up. Took me a couple of hours but I got the threads cleaned up and it works now thanks you very much!

  3. That was my first thought but it looks like it is bottomed out on the inside of fhe receiver. I was only able to get it to go a quarter turn in but not enough to line the extractor cut back up. After looking at some pics you may be right I will go back over and see if that maybe the issue. Its an all matching gun so its not a replacment part and the barrel has not been out of it since I first got it 4 years ago.

  4. My MP28 started doing something odd when the bt closes on a round the back end of the extractor pops out and prevents the bolt from retracting. Anyone dealt with a similar issue. It appears the extractor is just too loose but not sure what might be going on.
  5. There was no lock in the gun when I bought it. Barrel was barely tacked to the receiver. Took me about 5 minutes with a Dremel to free it. Purchased a lock in excellent condition from ebay and a used barrel from IMA. Gun will cycle and fire without a round in the chamber. But not with a round in it. Will occasionally fire if you draw theround out of the chamber halfway and release while hiding the trigger. Which indicates to me the headspace is only slightly off. My thoughts would be to take a few thousands of the slots on the breech face but I don't know for sure. Taken down the brass collar also seems like a possible way to get the barrel to move slight forward in the housing.
