My experience pretty much matches MOGC. I mounted a Burris FF II on mine and it is very accurate. A good cleaning and break-in period was critical and the more it settles in, the more accurate it gets. I have fires CCI MiniMags and Blazer out of mine with a few hiccups early but none in the last couple hundred rounds. I have about 1800 rounds through mine. I do shoot mine suppressed and the POI shift is consistent and only about 1.5 - 2 inches at 50 yards between suppressed and naked.
