You mean they made the Mark II ever harder to take apart?? I have, as the wife calls it, a mini rifle Mark II, if I remember right it has a 10" barrel. I dont think getting it apart is all that bad, it is putting the damn thing back together. A former shooting buddy has the same firearm. He ran 40,000 rounds thru it once before cleaning. And surprisingly it still performed well before he cleaned it. Sure do miss the days of going to a gun show and picking up a case of 11000 rounds of 22lr for next to nothing......
