It seems pretty apparent from the reviews accuracy is a serious issue with this upper. PSA, have you addressed this problem and what have you changed on the uppers that you are currently sending out the door today? I would like to buy one but do not want to have to send it back to have it fixed like many of the reviews state. I would rather wait for a product that is refined- has anything changed yet?

Wait and See
I was very excited to add this .22 AR upper to my collection. I mounted the new holosun red dot that I just purchased from PSA. Before heading out to the range I cleaned and lubed the upper . When I got to the range I ran 10 rounds of minimags do range. Everything went perfect. I moved over to the site in range load up 5 rounds federal auto match and she off a bag. I went down range and I had a shot gun pattern. I loaded up again, same thing. This went on for 50 rounds. The gun functioned flawlessly . But I could not get it to zero. I removed the red dot and mount it on my Ruger PCC. I zeroed in 9 shots. I looked it over and everything was tight.
I called PSA and they have it. I really want them to fix it. I was a great running pistol . I hope they can work the bugs out of this design . Waiting for my receiver to come back.

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 .
