So I finally got my stamp back and was able to pick up my MP5 from my dealer. It is a Vollmer converted HK94 with a Fleming sear. I had read that Vollmer was unique in that he actually put a correct MP5 barrel instead of cutting down the 94 barrel and threading it. I also read that for some guns he used Turkish contract barrels when he could not get factory ones. I was looking over the barrel last night and I cannot find one marking anywhere on it. I would think if it were a factory barrel it would have the date stamp on it either a 94 or MP5 barrel. Did the Turkish barrels not have markings? What else could it be? Not a big deal just curious what I have. I will take pictures of the gun this weekend and put them in the gallery but attached is a quick shot I made.
