Gen 4 Hybrid 9mm BCG, how does this differ from the G-9 Hybrid 9mm BCG?
JasonandErin C on Sep 26, 2018
BEST ANSWER: Can someone answer this please. My g-9 will not shoot glock 32 round mags.
will this work with an ar-15 lower with mag adapter?
john g on Oct 3, 2018
BEST ANSWER: Yes, there are many options of 9 mm Magwell adapters or there's the Mean Arms Endo Mag option which allows you to use your pmags and convert them to 9 mm.
Does anyone have experience with the Meanarms endomag being used with a PSA 9mm upper? Thanks for sharing.
Ted S on Feb 26, 2019
BEST ANSWER: Yes, they have been working great for me. Inserting them on a closed bolt requires a good solid hit, but other than than that the function has been flawless
Will this work with a PSA Blackhawk classic lower item no 8002 - designated multi cal?

PSA AR15 Complete BlackHawk Classic Lower - 5165448002
BEST ANSWER: Yes, you will need an adapter for the mag well to use 9mm.
does the slide lock back when the magazine is empty?
Jacob R on Feb 21, 2019
BEST ANSWER: Thats a function of the lower, not the upper. If you mount it on a "Colt" style lower, it will lock back as normal. If you put it on most Glock style lowers, they dont usually lock back.
can this be used with any 9mm lower or just PSA only??
walter h on Feb 21, 2019
Will this work with the STERN DEFENSE Glock magazine adapter?
Matt W on Jan 30, 2019
BEST ANSWER: have used several different brands of Glock magazines with no problems.
Will this fit a colt 9MM lower and function?
Robert W on Oct 24, 2018
BEST ANSWER: According to the description above, it can be used with Palmetto State Armory 9mm lowers that use either Colt® or Glock®-style magazines.
What is the thread on the 9mm barrel?
j H on Nov 8, 2018
BEST ANSWER: It is in the description, 1/2 - 36.
will this shoot +p ammo?
clay R on Dec 31, 2018
BEST ANSWER: From my own personal experience, this didn't even shoot regular 115 grain. It seemed like the bolt was opening a little too fast causing a lot of blowback and then the entire thing stopped working altogether.
Does this have a standard barrel nut if I wanted to change rail could I ?
Peter C on Oct 3, 2018
BEST ANSWER: I put together several 9 mm uppers and used AR-15 upper receivers so I see no reason why this PSA upper would be different and use a different barrel nut.
How come this 16” version has a 6061 upper when all the shorter length Gen 4 receivers are 7075?
Gino V on Dec 22, 2018
Will this work with glock style lower?
Brian g on Jul 3, 2019
BEST ANSWER: Yes, this works with Glock 9mm lower. I have PSA Glock 9mm lower on mine and it works great.
Will this work on ks 47 lower?
Steve C on Jul 7, 2019
BEST ANSWER: This 9mm will not work on a KS47 Lower.
I have a MAG Tech lower for my 5.56 carbine. Will this upper mate up with my lower or will I need to make some modifications?
kenstar23 on Mar 7, 2019
BEST ANSWER: it should fit but you will need to adapt your receiver to accept 9mm mags and you will probably need to change the recoil buffer to get it to run correctly
What buffer and buffer spring are required with this upper?
ThHighwayman on Jan 30, 2019
BEST ANSWER: I went with the extra power carbine spring (wolff) and a heavy 9 mm buffer (10.4 oz)
Does this upper have a bolt catch?
Thomas L on Nov 20, 2018
BEST ANSWER: From my personal experience when combined with the Colt magazine PSA lower the bolt catch will function, albeit intermittently.
1) Will this upper work with a Spikes Tactical lower? 2) will the bolt hold open after last shot / mag is empty?
Chris B on Apr 12, 2019
BEST ANSWER: It will work with it so long as it is a 9mm AR lower or you have the magwel conversion device for a 5.56 lower. Last round hold open is dependent on the lower not the upper but most AR-9s do not
What is needed to complete the rifle after you purchase this item and a lower that is purchased from this site?
Dirk R on Oct 27, 2018
BEST ANSWER: All you should need are sights of some variety and you'll be good to go.
Will this work on a Lone Wolf G9 lower?
Jon P on Feb 16, 2019
BEST ANSWER: Sure.
I just put a Colt lower on mine with a torkmag 9mm adapter to accept Glock magazine.
Purchased this but it doesn’t seem to work with my 5D Tactical dedicated 9mm lower. Nor does it work with my 80% Arms dedicated 9mm lower,,,,both Glock mags. Do these 9mm PSA uppers, especially ones with the Gen 4-9 BCG only work with PSA 9mm lowers? That wasn’t indicated in the product description...
John B on May 5, 2019
Anyone running the 16" PSA 9MM complete upper on an ATI polymer AR lower? Any issues? Thanks for any help.

Great upper for steel
I have two of these. Both are on PSA Glock magazine lowers. One was a PSA complete carbine that I replaced the more convention upper with, one was on a PSA lower. I set this up with a C-More Rail sight and a CMC 9mm Singe stage trigger and gave it to one of my students It is the perfect weight for steel competitions, and completely reliable. He has won two competitions with it in the three months he has been shooting.

Don't use RA-410 Drop-In Trigger!
Purchased this 8" and the 16" upper with Gen4-9 BCG. Was sticking when pulling back charging handle. Couldn't figure out the problem. Low and behold, one of the only drop-in triggers that won't work with the PSA Gen4 BCG is the Rise Armament RA-140. Replaced with standard Mil-Spec trigger and now works fine.

Perfect addition to a AR collection
I mounted this upper to a "Glock" PSA lower, shoots perfect.

I do like the "Colt" lower over the "glock", but they're always out of stock. The "glock" canted magazine just don't look right.

But, PSA is always quality.

Great plinker
Real fun gun to shoot. Cheap ammo, 100% reliable . Would like to have a fixed front sight and ejection port cover.

From 4” to 16” the 9mm PSA is a great bang for your buck!
A much more precise gun than its 4inch upper.
A general purpose carbine.
Goes well with PSA Glock lower or a modified Colt lower.
A good plinking gun as well a defense weapon.
And with 9mm being cheaper than the other AR 15 ammo you can stretch your bang for your buck.
And like the AR15 many use of optics or attachments on the M lok handguard.

Game changer
I've been purchasing PSA stuff for some time but this PCC is a game changer. I've focuses on pistol but have seen the expansion of PCC shooters in the past year. After 1000 rounds I can say it is exciting to go to the range again. At 60 yards the average shooter can place every round inside a quarter. It is crazy accurate and a blast to shoot. Building two more. They can be tricked out but just stock is fantastic. Best thing I own.
