I prefer the $200 CMMG .22 bolt. Just take your AR's bolt out, drop this one in, and proceed to drop zombies at about $.07 per round with Mini-mags. It's nice to be able to work out your own gun instead of a lighter version.
That awkward and funky 180 degree sweeping safety that comes on the Colt 22 AR is one feature that tells me I'd never buy one! Why did they do that?
The 22 AR conversion is nice if you already have a 223 AR. If not, I'd opt for a S&W 22 AR or go with the GSG 22. Both seem to be better guns.
Or..save a ton and buy a 10-22 and some high cap mags and know you're getting something that will be trouble free for a very long time.

I like my GSG-5 anniversary edition a LOT!!!!
If the Colt were $300, I'd probably buy one just for the novelty. They are picky in ammo though, Federal bulk seems to run the best so far. They are fun with a can though....

You are correct, mine loves Federal Bulk as well as CCI Mini Mags
