I have had no FTF's of any kind. I've used all kinds of .22 ammo. Some thats over a decade old.
Just get one, you won't regret it.
Mine is a little more picky about ammo than some of the others have mentioned. It does perform well with CCI Mini-mags and has some issues with a few other brands. I have only put approximately 400 rounds through mine thus far and I hope the more I use it the more reliable it will become with other brands.
I got mine a couple of weeks ago and have been using American Eagle 40gr high velocity in lead with no problems, I put 750 or so down the pipe in a couple of range sessions and just put a few .223's down range after to clean the barrel out, it works great

750rds no problem...Its good to go!!
Any issues cleaning the lead residue??

The .22 conversion is is awesome.
The only downfall I've noticed is that .22 ammo is D-I-R-T-Y.
Airborn_69 - I've had no problems with cleaning it. It is just dirty. This could be because I will fire up to 500 rounds of .22 during a session v.s. 100 rounds of .223.

I took a brand new one of these out for a spin last weekend. Oiled up all the moving parts before starting. Had 2-3 failures per mag with every type of ammunition I used (Federal Bulk, Winchester X, Remington Thunderbolts, CCI Blazer). I found the extractor was the biggest problem. Not all the spent cases would reliably extract. The scary part was that even though the kit was causing stovepiping of rounds, the action would still strip the next cartridge and load it into the chamber. Meaning, the half ejected casing was getting jammed into the back end of a live round. This lead to one out of battery fire in about 200 rds fired.
Needless to say, I'm not really pleased.

Been told that American Eagle works best..
It stays open on the CMMG kit until the mag is removed and then it closes, there is no way to keep it open without the mag.....
I see. I don't have to worry about dry firing by accident. THx
An upgrade I'll consider sometime down the road.
Fired a few variety of mix ammo.
Didn't like the ''C'' marked ones, just for feeding, the bolt wouldn't catch the rim unless I tilted the mag forward. It eats american eagle...Had 2-3 stoppages with the first 2 mags, then it fired flawlessly. Same zero as the .223 up to 100m
Highly recommended on the Norinco.

I built a dedicated .22 LR upper with a 1-19 twist barrel(for the long rifle ammo)yesterday. I used the original Colt .22 convertor unit and tried it out. It went through 400 rds of cheap Federal standard ammo without a flinch. Happy camper
I to officially have a higher ratio designated upper for the 22lr now...My advice ladies & gents, get one! They are a blast..
