The Mark 1, 2 and 3 series all use a mechanism at the rear of the grip to secure the upper receiver to the grip frame. Reinstalling it is, yes, an excercise in frustration to say the least. And if you try to force it, you will damage something.
Unless I have some real need to remove the upper from the lower and remove the bolt, I don't bother doing battle with it. When it gets that filthy, I remove the grips and hose the whole thing out with carb cleaner and scrub the stubborn stuff with a toothbrush.
The gun however, is a great, in my opinion, one of the BEST semi auto .22's out there so I wouldn't let the disassembly lever in itself disuade you from getting one.
