BTW, I got that AM-15 yesterday and we put 60 rounds thru it. Totally excellent firearm. It had no sights, so I put the red dot on it. Hit cans from 50 yards no prob. Hit milk jugs at 75 yards no prob. And I know the exact range from the range finder readings. Tomorrow my brother and I are going to clean a bunch of my guns and he is going to break down my little Winchester model 190 .22LR because it has been jamming more and more lately and see what may be the problem. I'm also going to try shooting some high velocity rounds thru it and see if that helps. The Remington rounds I was using were supposed to be fast, but I have some Winchester high velocity rounds I have never used and we'll see if they work better.
