.22 AR Upper that's worth a damn?

[Ranger Psych]

Looking for a .22 upper, complete replacement... figure I can use it to train with generally the same muscle memory etc, as well as be able to pimp a platform I like for taking out small game.

any suggestions? No bolt replacement kits, i'd much prefer an outright replacement unit.
