When will this be back in stock?
Tyler M on May 3, 2018
Is the flash holder pinned on or threaded? I'm lookomg for a dedicated .22 upper than can accept a screw on suppressor, hoping this one will work.
J B on May 19, 2018
BEST ANSWER: It says the muzzle thread is 1/2-28
What PSA Lower would you pair with this? Is there a complete one that is not a kit?
Andy From TN on May 9, 2018
BEST ANSWER: Any of the standard AR lowers will do. For 95% manual of arms compatibility, get a "Better-Mag" adapter to use SW-15/22 magazines.... Or better yet get an ARCatch-22 bolt catch replacement and use SW-15/22 or Kriss Defiance mags for 100% manual of arms compatibility.
Just bought one and it is one way. I am going to build a dedicated lower for it. Do I need to install a buffer and spring in the buffer extension tube to hold forward tension on the BCG?
Steve D on May 18, 2018
BEST ANSWER: The buffer detent is what holds the .22 bolt carrier in place, as it's solid in the bottom, there's no cutout for it to pass over the detent like on a regular bolt carrier. So the spring and buffer is NOT essential to function in a .22 caliber version.
Will the cmmg magazine work with these 22lr uppers?
John S on May 20, 2018
BEST ANSWER: Yes they will.

Great product! If you see this in stock, pick it up before its gone!
Awesome upper! Had no issues with fitment, function whatsoever. Typically, .22 is pretty finicky specially with ammo but this upper matched with my PSA ept lpk works amazing!

Best value for a dedicated 22lr upper!
If you ever find one of these available don't hesitate and hurry up and snag one. These get sold out fast and take a long time to get them in stock.

Worth the money!
I wanted a dedicated .22LR upper and PSA came thru. It mated perfectly with my PSA lower and performed excellent. I am very happy with my purchase. PSA does it right again!

Very good, especially for the price. Would suggest to a friend.
I wrote a review on Reddit already (link below)

Seems to feed pretty well with M&P 25 round mags, but I have trouble whit the 35 round mags. Will need to do more experimenting.

Perfection
I'm always suspect of positive reviews, to be honest. But I am compelled to write this out of appreciation for such a fine product. Perfect fit with my Rock River lower, and loved that its 'real steel' vice plastics. Machining of rails, parts precise and crisp. Bought with 2 Black Dog mags, and was pleasantly surprised I had zero failures to feed over 200 rounds. Topped with a Vortex red dot, and accompanying photo shows a TYPICAL grouping at 50 yds, shooting from rest, with dot covering entire bullseye; 8 of 10 rounds making "one hole," 1 round slightly off, and 1 round a called flyer due to my jerking the trigger.
50 yds, CCI std vel 40gr x 10 rds. Red dot covered entire target so less precise than scope reticle.

A dedicated 22 lr AR
Mounted on an Anderson lower w\ holosun 515c and S&W mag adapter. Zeroed at 25 yds and produced decent accuracy with bulk ammo, 1.5 in. The mag adapter locked the bolt back on full mag several times, but after several drops of oil applied to the part that engages the bolt catch the issue was corrected. Fit and finish is good as expected. I cant wait to use this gun in the local speed steel match.

Finally a well made dedicated complete 22LR upper that isn't $500-600.
I initially purchase this to swap onto my main AR but ended up putting it on a dedicated lower since in CA, with 22LR we can have a regular mag release and all the evil features.

Right off the bat, with the newer Black Dog magazines, the bolt holds open on the last round, but drops once the mag is removed since the bolt is resting on the feed lip of the mag. No good. Even my crappy Colt Umarex M4 22LR has a proper Last Round Bolt Hold Open (LRBHO) function.

I then saw in someone else's review about a "Better-Mag" adapter that in conjunction with SW15-22 mags, would have LRBHO function. Great, I tried that out... it works and gives you LRBHO and the bolt stays open when you remove the magazine. BUT, you can't manually lock the bolt back by pressing the bolt catch and pulling the charging handle. Not a showstopper, but not 100% like the real thing either.

After searching around for bolt hold open adapters and such, I came across the ARCatch-22. It's a bolt catch replacement that is designed to hold open Ciener/Atkinson design 22LR bolts. It does require replacing the bolt catch and using magazines with a follower design that can activate a bolt catch. Since I'm using a dedicated lower, no problem replacing the bolt catch. With the SW15-22 mags, they do require sticking a shim onto the front of it due to the mag design. Kriss Defiance mags have a bolt catch activator and doesn't require a shim. With this combo, the bolt holds open on the last round, stays open on mag release, and can be held open manually by pressing the bolt catch. 100% like the 556 AR.

Best of all, with 6x FFP optic, I get 4in groups with Federal Automatch and Winchester M22 ammo at 100yds. Not bad and definitely good enough for running AR skill drills. Great job PSA!

I’m in love with this plunger!
This upper is fantastic!! Paired mine up with a Honey Badger Spikes Tactical lower from one of my AR’s. Very light weight and well made! Thanks PSA, you guys knocked this one out of the park!!

Still trying it out.
Haven't had enough time to try upper assembly out on different AR platforms at this time. Fits fine & cycled flawlessly on lower first installed. This is a training unit for grandkids and they should all enjoy it!
