When will this be back in stock?
Tyler M on May 3, 2018
BEST ANSWER: Right now on 26 September 2018. I'm about to order one.
what is the weight of the upper?
ed t on Jul 17, 2018
BEST ANSWER: 3 lbs 10.4 ozs (without optic or sights)
Do you know when you will have this upper in stock?
jason m on Jun 19, 2018
BEST ANSWER: Unfortunately I do not have an eta for production at this time.
Is this BCG compatible with a CMMG full auto adapter for use with a fostech echo trigger?
Caleb G on Jul 19, 2018
BEST ANSWER: I used the Fostech auto sear and weighted forward assist, their auto sear is already “bent” where it meets the Fostech trigger lock and brings the lock forward to disengage the lock. The auto sear has to float freely, I don’t think the CMMG one does unless you clip off the two side tabs or “ears”.
I know it specifies blackdog mags, but will this function with cmmg mags or any other company mags? what are yall paying per mag? thanks.
Perry B on Aug 31, 2018
BEST ANSWER: Yes.. I run cmmg mags in mine and they run fine. Bolt locks back on last round as it will catch against the follower which is actually a nice feature to be able to clearly inspect the chamber to make sure there is not an unfired or unextracted round still loaded
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: The flashhider is not pinned. It has a standard A2 birdcage threaded flash hider with same threads 1/2 - 28 as all standard milspec AR15 barrels. I removed it an installed a different one.
Is there an eta of when these will be back in stock?
Michael P on Sep 15, 2018
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.
Will the cmmg magazine work with these 22lr uppers?
John S on May 20, 2018
BEST ANSWER: Yes I had 3 25 rd CMMG mags that worked perfectly
this is for a products expert I think. What is the difference between the 22 rifle 6934 and the 8928 besides the Stainless Steel bolt group as opposed to the Phosphate one, $100, and the one is not in stock. But when it was it was $249. I just RECEIVED the 6934 on 7/24 and on 7/26 got the ad for the 8928. The SS Bolt can't be worth $100 more so what did i pay an extra $100 for? Thanks
Saywhat on Jul 27, 2018
BEST ANSWER: 8928 was sold as a clearance item at a reduced price. Besides shipping with the phosphated bolt, that item also came with a different styled rail.
Why not redesign this and put in a slickside upper receiver since the assist and bolt catch don’t work anyway with the bolt your using or change the BCG?
Harold B on Jul 16, 2018
Has anyone seen if their barrel is an M4 profile?
Emmanuel L on Oct 8, 2018
BEST ANSWER: Just received mine and no it is not M4 profile. It's much lighter. Not sure why the change and I'm a little disappointed, was hoping the weight would be closer to my 5.56 upper.
will this fit on a mil spec ar15 lower?
manovan on Jul 18, 2018
BEST ANSWER: I put this on an Anderson Arms lower I had built for an AR15 build. The pins slid in perfectly and it had no function issues at all.
Does this use a 556 lower?
joshhsoj on Jul 20, 2018
BEST ANSWER: The whole point of the upper is to fit onto a 556 / 223 lower, so yes.
Is it a last round bolt hold open?
Rrotz on Jul 18, 2018
BEST ANSWER: yes the mag follower holds the bolt open not the bolt catch
Can I dry fire this upper or will it result in damage?
Daniel P on Oct 6, 2018
BEST ANSWER: Dry firing centerfire cartridges is different than rim fire. Excessive dry firing on a 22 rim fire could and likely result in dulling the firing pin and resulting in misfires. Center fires when dry fired strike nothing, rim fires strike the steel of the breechface.
What are the benefits of this over the Smith & Wesson MP 15-22?
Ak T on Sep 26, 2018
BEST ANSWER: Benefits, full weight for life like training. The m&p although a good rifle is light and feels like plastic imho. This upper is very solid and has not disappointed me at all. I’ve ran over 700 rounds without cleaning and it still works fine. I like to see how many rounds I can put before I start getting problems. I’ve can get quarter size groups at 50 yards with cci mini mags. I liked mine so much I got another and am planning on buying another soon. I was gonna buy a sw mp 15-22 for my 9 year old daughter but I figured she will grow into this one and can always change to a regular upper and not notice the weight difference.
What ammo runs best?
Stephen B on Jun 22, 2018
BEST ANSWER: I run CCI SV suppressed and it works great.
What are the benefits of this dedicated upper over getting the Smith and Wesson MP 15-22?
Ak T on Sep 26, 2018
BEST ANSWER: IT gives you the ability to change to different calibers by simply switching out uppers.
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: It may work without the buffer and spring but they seem to help hold it forward. Both my dedicated 22lr ARs have buffers and springs in them.
When does PSA expect to have this one back in stock?
tom s on Jan 8, 2019
When will this be back in stock?
Ddddjj on Jan 1, 2019
What lowers will this upper fit ?
Guinn J on Jan 13, 2019
BEST ANSWER: This 16" 22LR upper should fit just about any AR-15 lower. One of the reasons I bought mine is so I can shoot 22LR from my AR lower to have the same trigger and grip setup. It looks and feels identical to my 16" 5.56 AR upper.
Will this work with a standard PSA AR-15 lower.???
Anthony M on Sep 26, 2018
BEST ANSWER: It works with any Standard AR15 lower.
What all different brands of magazines will this up accept besides the madog mags? Thanks in advance!
Cabinetguy55 on Jan 13, 2019
BEST ANSWER: I use S&W m&p magazines. The 25 round ones work perfect. The 35 round ones (which I don't belive are official S&W) seem to rub the bolt, and cause jams. I've sanded the lips of these down and they work better but I'm not 100% confident in them. You will not have the last round hold open by default with this upper. I installed a catch 22 on the lower to get this functionality and it works perfect. I know some people use a redi mag, but I can't speak to it. The problem with the catch 22 is you can't run standard 223 mags anymore, so you will basically need a dedicated lower.
Black dog 10 round magazines work the best or what do you guys use?
Brownm on Jan 12, 2019
BEST ANSWER: Yes those should work fine. I use Cmmg 25 rounders in mine with no hiccups. I also have a PSA pistol upper with a 4.5” Cmmg 22lr barrel that I have the “better mag adaptor” installed in the lower that allows me to use S&W 15/22 mags which are way easier to load imho
What magazines can I use?
David W on Sep 26, 2018

I use Black Dog Machine magazines; I think they're pretty much the best you can get and they're not expensive. My experience is limited to their 10-round version (thanks, California) but from what I read elsewhere all their products are well made and they supposedly offer good support.
Can I purchase an extra bolt? I have issues with the first one needs to be replaced. Didn’t even get 30 rounds through it
David A on Sep 3, 2018
BEST ANSWER: I have a lot of rounds thru mine...if you're having a bolt issue, I'd contact PSA first. I can't imagine what you'd have to do to break the bolt.
Will this upper work with timiny trigger?
Addison C on Jul 24, 2018
BEST ANSWER: I don't see why it wouldn't. from my experience the only issues that people commonly encounter is when using a military hammer with the hook or notch on the rear. Most commercial triggers do not have the notch or hook. I have a match trigger in my lower and it works 100%. My PSA 22Lr works great and has proved to be 100% reliable so far.
Is the upper able to run sub-sonic ammunition (CCI 40grain 1050fps HP, etc.) without problems?
David T on Jul 1, 2018
BEST ANSWER: Haven't tried subsonic, but Federal bulk constantly FTE. Minimags, Yellowjackets and Stingers all worked without a single hitch. I suspect it needs warmer ammo to operate the action, but it may need a few thousand rounds to break in a little too. Really like the upper though; with no wind its fun plinking golf balls at 100yds.

I love this thing.
Excellent setup. I was out at the range sighting in my scope for this, which is a cheap scope I got off Amazon, using Amazon rewards points so it was free, who doesn't like free. Got it setup quick and easy. The guy next to me had steel setup at 150 & 200 yards and said I could hit it if I liked. After burning up the bulls eye on my sight-in target, I decided to try his 150 yard steel. Ding, ding, ding, ding... No problem, then his 200 yard steel, which I could only see 1/2 of because it was set low and my bad angle had a pile of dirt blocking some of it. Yet, ding, ding, ding, ding.... No problem... That guy was struggling to hit it with his 5.56 AR-15...
The point is this worked well, stabilized the bullets well. And easily stayed on target once the scope was lined up... I love this. The weight, feel, and mechanics are the same as my 5.56 and 300 BO versions but I can practice at about 5 cents a round rather than 30 - 50 cents a round... or more.

Don't bother with cheap bulk pack ammo for 22LR the savings are not worth the frustration the failure rate causes. This is not limited to this complete upper, I have several 22LR pistols and rifles. Unless you are using a bolt action, which seems more forgiving, or a revolver, the failure rate is too high with bulk packages. Stick to better packaging any you'll be happier.

new 22
Wanted to get one of these uppers and was able to do so. I already had a suppressor from my 10/22 which works great. It doesn't cycle my quiet rounds but the full power work great. My rodents know to be on the lookout at my place.

Great product
Great product. Put on an Anderson lower, shoot a great. I've only shot about 200 rounds through it so far.

Pretty great and also accurate
Love this dedicated .22lr upper, super glad I bought it. Great trainer. Eats everything I've thrown at it - except won't fire stingers due to longer brass.
And way more accurate than expected! I ended up putting a straight cmc trigger on it to closely replicate my ar15, and with cci standard velocity ammo it puts 5 shots into a quarter inch 3 out of 4 times. Shoots between half inch and inch at 50 yards with basically any decent ammo.
Like I said, love it.

Surprisingly accurate. Great value!
Overall a great value for the money. Quality components and the barrel shoots a little less than 1 moa with the right ammo. I shot CCI SV, Wolf Match Target, CCI Green Tag and Prime Subsonic and this particular barrel grouped best with the Prime Subsonic. All the others were decent as well, shooting around 1.25MOA. For an AR platform, I'm a happy camper.

Works for me
Working well for me with about 300 rounds through it. Only had problems for the 5-6 rounds. Probably things a bit stiff. Worked fine thereafter. Only complaint is that it's not the best for teaching manual of arms as mags don't drop free or even remove easily.

Wont be disappointed
Love it! This beat my expectations. Put 400 rounds first day straight out of the box. Not one issue.

Spend your money on other 22s
The one I received should have been a blem. Two corners on the handguard are just (crushed) where someone hit it to adjust during assembly. Accuracy is mediocre at best. Have $500 into this gun. Could get something more accurate for a lot less.
