You have had accuracy issues with your pistol uppers in the past.
Does this function correctly and is it accurate?
Tom C on Feb 18, 2019
BEST ANSWER: I’ve had mine for a couple of weeks, sits on a Rock River Arms lower with the RRA Match trigger. I put a Nikon Prostaff 3-9X Rimfire scope on it.
After about 200 rounds I’m getting 1/2 inch 5 shot groups at 50 yards using CCI Standard Velocity ammo.
What type of magazine works with these 22 uppers and where can they be obtained?
Larry D on Feb 14, 2019
BEST ANSWER: CMMG or Black Dog Machine mags work. You can get the magazines from anywhere that sells those brands.
Does it Stay open after last round?
Chick on Mar 4, 2019
BEST ANSWER: The bolt hold open doesn't work but the magazine follower does hold the bolt open until it is ejected.
Does this use a CMMG bolt or another brand?
Chris D on Feb 27, 2019
BEST ANSWER: It appears to me an unbranded cmmg bolt, it's exactly the same. They are very nice ...smooth, polished stainless steel. One commenter mentioned that the newer model has a cotter pin for the firing pin. This one does not, so it might be the older version but it is just fine.
Is there a special lower for this concerning the mags? How does this work?
Randall B on Feb 14, 2019
BEST ANSWER: Any standard lower will work. Uses Black Dog mags. S&W 15-22 mags work with an adapter from Boonie Packer.
So will my psa complete lower work with this upper?
Brock B on Mar 3, 2019
BEST ANSWER: Yes, if it is a standard AR-15 Lower.
Can this be used on a pistol lower?
MTL S on Feb 28, 2019
BEST ANSWER: Pistol Lowers can be used on all Pistol and Rifle Uppers. Rifle Lowers cannot be used on Pistol (less than16 inch) that Lower is registered as an SBR, Short Barreled Rifle.
Does the .22 upper require a lower with a buffer spring? Or can the buffer spring/tube be omitted?
Brian M on Feb 19, 2019
BEST ANSWER: No buffer or spring is necessary, the bcg cycles within itself - nothing needed in the tube, the design will keep the bolt from going back into the tube
Will this work with a M16 lower in the happy mode?
PSAAA on Mar 13, 2019
BEST ANSWER: I have the 8.5 version and it runs in full auto. You have to buy the cmmg auto sear trip kit
Can this be sent to my house?
Mark B on Mar 12, 2019
BEST ANSWER: Yes, if you live in a legal state that will allow it
Is this compatible with any AR15 lower receiver? Specifically a Ruger AR556 lower.
Chaw179 on Feb 22, 2019
BEST ANSWER: Any standard mil spec forged lower, but, you need s rounded ( not notched ) hammer.
I have tried this on a billet lower, and the magazines seem to fit loosely.
What is the total weight of this?
Jeff K on Mar 20, 2019
Is this upper could be ship to California?
Emmanuel on Mar 12, 2019
Will this upper function with the Fostech Echo trigger?

PSA .22lr upper
I was hoping for decent accuracy out of this, but I was pleasantly surprised when this equaled my tricked out match 10/22 which cost me way more money., It has the original miss-shapened extractor, but it still works fine with CCI Blazer.
March 17, 2019
I received this upper in the mail yesterday along with a cmmg 25 rnd mag and installed my 6.5 creedmoor's scope on a qd mount. It groups pretty well for a .22lr it will definitely do better with more consistent ammo and a more steady hand. Out of around 150 rounds I had one failure to feed and it had one round get stuck in the chamber once it started getting dirty.

30 yard groups. These are not the best groups I had. I was testing return to zero of my mount.

Accurate as hell
I was a bit hesitant to buy a PSA .22LR upper since I had heard of accuracy issues with the first batch. I have an adapter that lets me use M&P15-22 mags (worth it's weight in gold) that I dropped into one of my AR lowers. With good subsonic ammo, this upper, and a Vortex 6 x 24 scope I can literally pile all of the bullets into one hole at 25 yards. Ridiculously accurate.

Good deal and a good product
Nice upper, packaged well and sturdy boxing, light Handguard -looks great. Works very well with Federal champion copper plated bulk ammo ( blue 525rd box ). Fairly accurate so far- 4 stars. Also cycles very good with Winchester super X and Aquila., 100%. For reasons of the Remington golden bulliets projectiles being loose in their crimps - the Remington golden bullets do not feed / chamber well, when they don’t I experienced a lot of lead shavings from the chamber- I have other 22’s that love it but this does not- that being said there are endless choices of anmo to choose from that work well. I have tried black dog X form mags, 2A mags ( which are made by Black Dog) and CMMG Ceiner mags, all were 100%.
