I'm willing to spend the extra $$ for a dedicated .22 upper so I can get good accuracy and cheap practice at the 50yd range.

Any recs on dedicated .22LR uppers? Right now I'm considering these two:

.22LR Upper M4
Match Quality Green Mountain barrel

CMMG M4 Dedicated .22LR Upper

Spikes likes to talk up their stuff a lot:

This upper utilizes the correct 1:16 twist rate for the .22lr bullet and eliminates the problem of fouling AR15 gas tubes with dirty rimfire ammunition. All of our uppers come standard with Match Quality Green Mountain barrels.

Regarding the Spike's Tactical .22lr bolt. Our bolt is based on the Atchison design with improvements including the following: an electroless nickel finish gives it a much slicker, smoother finish so you do not have to run it as wet which means the bolt stays cleaner longer. We have changed some tolerances, beefed up the firing pin and pre-drilled for a ball-detent.

CMMG doesn't say much but they have a good rep. Thoughts? Other suggestions?

Personally, I'd go with the Spikes Tactical as I have several friends who own it and have had great results. They all fire full-autos with it. They also owned the Ceiner model, but I believe most of them have sold it. I'm not aware of anyone who has used the CMMG.
