Looking for dedicated 22 upper

[Water63]

OK I am building my first black gun and think it would be fun to get a dedicated 22LR upper. I am looking at the CMMG right now I called Spikes and they have discontinued their 22 LR upper. I really don't want to put a conversion in because I want this set up to be pretty accurate.
So what is out there and what should I stay away from.

I'm considering going with the Tactical Solutions M4 .22 upper.

No personal experience but, I've seen the CMMG conversion on YouTube, and it looks to fairly accurate. Whichever way I go I intend shooting it a FNS and probably use it for squirrel. From what I've seen, the CMMG conversion would be accurate enough for that.
