Will CMMG 22 AR magazines work with this upper?

BEST ANSWER: Yes, black dog, cmmg, and most other 22lr magazines are the same design. The only magazines that don't function are for the Olympic Arms AR 22lr rifle.

Terrible accuracy
When I bought this upper no reviews had yet been posted. I've shot it once to sight it in and the shots were all over the place at distances of 10 yards and further. Was also using a new red dot sight, so that that might have been the problem. Now I see many others are experiencing very poor accuracy with this upper.

This is the first PSA upper or lower I've ever experienced problems with accuracy wise. PSA, please help on this one?

Fit great.
Fit easily on my PSA lower. I bought this dedicated 22lr upper to improve accuracy with the 1:16 twist. Still need to check that out at the range.

PSA 7.5" .22LR 1:16 Nitride 6" Lightweight M-Lok Upper
While this fit & finish of this unit is excellent, I was unable to shoot groups smaller than 12 inches at 10 yards, regardless of the ammunition I used.I believe that the barrel has the wrong rate of twist for a .22LR bullet. I shot normal size groups with every other firearm I shot, so it wasn't a case of me having a bad day at the range. The strangest thing is that the geometries of the unit are perfect, so it never jammed (a typical problem with .22LR conversion units)- it just wouldn't send the bullets in the same direction twice.

Accuracy not great but good value at price point. Has run flawlessly ~800 rnds.
Accuracy isn't great do to fliers. Also experiencing heavy leading in flash hider. Over all a good value for price point despite said issues. Has run flawlessly ~800 rnds.

Potentially Great
Purchased late August, sent back to PSA twice,(as of this writing it's still there awaiting a second new barrel). Both original and first replacement barrel gave shotgun pattern like groups at 25 yards- random hits with evidence of bullet tumbling. Didn't slug the bore but suspect it's oversized.

I've purchased 3 other .22LR uppers from PSA: two 16" that are wonderful, and an 8.5" also back awaiting a good replacement barrel.

Would have given single star except for the unexpectedly excellent customer service PSA exhibits in working to resolve these issues.

Love love love my 22cal!!!
I love love love this PSA 22cal. It is really fun to shoot. In fact i am writing this review as i am taking a brake in the shade from shooting 250 rounds thru it. I love to shoot plinkers that i made as i move through my course of targets. I love the report of the “PINGGGGGG......” ! This is SO FUN & ECONOMICAL. I now own 5 firearms that i purchased theu PSA and dont see myself really needing another dealer in the future .

Functions fine, but terribly inaccurate
The upper works perfectly and I haven't had any issues with reliability, save for the occasional case getting stuck in the charging handle groove (but that is inherent in the design, and no fault of the upper). However, the accuracy was just awful. Not sure what is causing the issue, but I am sending it back for a replacement. Hopefully PSA irons the kinks out, because I can see this being my most used gun otherwise.

Its a blast!
I am still unsure on accuracy, but it does function fine with black dog mags. It also will feed fine with smith and wesson mags, although they have more play in the magwell. I am 800-1200 rounds through this, between federal bulk, and cci standards, cci subsonics, etc. it runs reliably, unless you put it on a binary trigger. Then it does have a hang up at least once per mag. As for accuracy, folks idk quite yet. Havent sat down and put it on paper at 50 with a good scope yet. But i bought this as a screw off gun anyways! I wanted to know if i could handle the 7.5 556 upper. And the 7.62x39 uppers at this length. I would say, yes its a sweet little package, but i believe muzzle blast, unless suppressed on a 556, would be a little to short for me. This does run reliably suppressed with cci standards
This is on a chevy silverado seat. This is a very compact package.
This is a vortex viper 3-15. The scope it nearly to long for the thing!
10-4-18 got this guy at 70 yards.
