Is the barrel threaded or is the flash hider welded/permanent?
Ian M on Feb 18, 2019
BEST ANSWER: Threaded.
Is this only full auto? I don't want full auto. Thanks
Matt S on Feb 19, 2019
BEST ANSWER: The full auto profile of the bolt carrier group allows this upper receiver to be used on a full auto lower receiver. As long as you do not attach it to a full auto lower receiver, it will not be full auto. A full auto profile bcg is not what makes a comeplete rifle full auto, it only allows a full auto fire control group to function.
Can this be shipped to NY state?
Chris on Feb 13, 2019
BEST ANSWER: Use the Contact Us link to ask PSA directly.
Can you add lights foregrip and maybe a bi pod to the rail I cannot tell from the picture...?
Jason G on Feb 15, 2019
BEST ANSWER: its an m-lok upper so you would need to buy a m-lok rail or a m-lok specific foregrip/bipod attachment.
What lower will work for this?
Shotgun on Feb 18, 2019
BEST ANSWER: An Smith & Wesson M&P Sport lower worked perfectly with this upper.
I received this upper yesterday along with a blackhawk lower, I put both of them together, and there is a slight rattle between the 2 parts, it is not snug as I expected to be, who do need to contact to address this?
Thank you.
Abbas O on Mar 2, 2019
BEST ANSWER: It's common and usual for uppers and lowers to have some play. they sell 'shim kits' that fill the gap but it's nothing to worry about
Does this bolt carrier have the PSA logo visible through the ejection port?
tommy on Feb 25, 2019
BEST ANSWER: Mine does not have a logo anywhere on the BCG
Are PSA upper kits like these with barrels and BCG’s pre-head spaced for a “plug and play” functionality with any completed lower?
Matthew F on Feb 25, 2019
BEST ANSWER: I put this on a completed lower and it was good to go. No tuning needed just zeroing your irons
Any idea on when these will be back in stock?
Steve on Apr 1, 2019
Who makes the barrel and what is the weight of barrel and barrel nut?
Kemosabejr1 on Feb 24, 2019
BEST ANSWER: DC Machine (owned by PSA) supplies this and most PSA barrels, the weight of the barrel separately is 22.8 oz.

Exceeded expectations so far
This is a longish review. Bottom line is I would buy this again. It impressed this novice AR user.

Longer version:
I was looking for a lighter weight upper than what I had been using and this one shaved off about one pound. It handles well and was 100% reliable.

This rifle is more accurate than I am and I was able to hit some steel at 300 yards with a basic red dot sight. I would purchase this product again based on what I know thus far. I don't rate many things this highly. The only negative I found was that the hole on the hand guard I thought was a quick detach point did not work with my Magpul QD unit. That was remedied by adding a QD mount.

The product was packaged well and arrived on time.

With only about 1,000 rounds through this upper, I will leave evaluation of its durability for later but had zero issues thus far. The upper performed flawlessly during a carbine class. We ran enough drills to heat things up and the components performed as it should, i.e. gas block was stable, screws staying where they should, BCG solid, etc. Having used carbines and mid-length systems previously, I was reminded of the slight increase in smoothness of this longer gas system. The ejection pattern with a stock carbine buffer seemed just right with XM193 ammunition.

The hand guard has a good feel to it and did a good job keeping hands protected from the heat from the pencil barrel and gas block. This is the first coated BCG I have used and I would say it is easier to clean than a milspec unit but I'm fine with either.

The milspec charging handle is not for me so I swapped it before the class I mentioned above. I'm glad I wasn't paying extra for something that I was going to replace. I assume PSA knows purchasers are likely to do that and this helps keep the cost down.

It is a nice bonus that it comes with the Magpul BUIS. Simple but useful.

I can compare this directly to a Smith & Wesson M&P and a Springfield Saint that I had some time with at the class and I prefer this upper to those products.

Great Value
BCG is easier to clean with the coating and sights are adjustable so great value. No issues after 400 rounds. Only thing certain picatinny rails are hard to get the screws in so M-Lok rails are a must.

Definitely worth it and then some. You won’t regret it.
Absolute tack driver. Wasn’t sure if it would be for a light setup or just something to dump rounds into. Well after dropping it on a Spikes and a 3x9x40 AR optic Bush. and popping a CMC 2.5lb trigger in it, I’m at 1 MOA with 55gr nato 5.56. The 1/7 twist has me eyeing up some 77gr Mk262 stuff to see how much I can punch it. Wasn’t expecting this from something priced so low. The deals man, the deals. If anyone is on the fence about buying this or any of their uppers, don’t be. You will absolutely not be disappointed.

Great upper assembly - High Value
Overall, I'm thrilled with this lower. It's lightweight, well-balanced, and very accurate (POI shift once heated up is minimal, at most). I really love the feel of the handguard as well as its aesthetics. The nickel boron BCG is smooth as glass and easy to clean. I give this 4 stars because I wish the QD sling mounts in the handguard were anti-rotational and because there is a gap between the handguard and the front of the upper receiver. If it were seamless, it'd receive 5 stars easily.
