Is the opening of the rail wide enough to put a suppressor on?
Tim D on Mar 25, 2019
BEST ANSWER: No, the hand guard is VERY slimline, but it’s also excellent for gripping. I would suggest going for the 8.5” barreled kit that has the 7” handguard if you want to run suppressed. Unless you are running an integral or a pinned/welded suppressor, save yourself a lot of headaches trying to get the suppressor on and off by making the barrel at least 1/2 to 1” longer than the hand guard (check you suppressor manufacture for mounting requirements....they can differ between direct thread and a quick attach mount).
Will you be offering this in a 5.56 caliber and a pistol kit soon?
Vj F on Jan 24, 2019
BEST ANSWER: Too small in diameter to accommodate pretty much all the standard 30 cal suppressors I know of
What is the inside hand guard measurement?
David B on Jan 21, 2019
Can you put a suppressor on this barrel?
Joshua C on Jan 30, 2019
Correction. What is the OAL length without the brake including the arm strap in its shortest configuration?
Andrew W on Jan 28, 2019
Is this a reliable shooter un-suppressed as is?
Johnny W on Apr 4, 2019
BEST ANSWER: No. I have not been able to get it to function properly. It will not chamber the next round
is the barrel already threaded for a suppressor?
mdean94 on Jun 2, 2019
BEST ANSWER: Yes, it comes threaded 5/8 x 24 which will fit most 30 cal cans for direct thread and any comps, flashiders, etc.
Can I just bolt this to my Palmetto State Armory pistol lower and be ready to shoot with a magazine?
Mike M on Jan 26, 2019
BEST ANSWER: Ive purchased other complete uppers before, and yes. Simply attach to a lower, and load. But it is recommended to clean before firing.
What lower goes best with this upper?
Dorn R on Feb 5, 2019
BEST ANSWER: Stick with PSA, saves problems!
I just purchased this upper. I have a PSA complete lower. Will I need anything else to complete my build?
Corey J on Feb 5, 2019
BEST ANSWER: NFA applies if your lower is a rifle build. other wise you could end up with an SBR all NFA rules apply! Tax stamp, etc. etc.
Is this upper legal in Washington state?
D M on Jan 30, 2019
BEST ANSWER: Yes
Will this upper have to be shipped to an FFL or can it be shipped straight to my house?
D M on Jan 27, 2019
BEST ANSWER: This will ship directly to your home. Only lower receivers or complete fire arms ship to FFL's
What are the small circular holes located next to the QD mounts and in between the M-LOK channels for exactly?
Aggie96 on Jul 16, 2019
I live in California, can this be shipped to my doorstep?
Chris L on May 2, 2019
What gen lower best fits this bcg?
Peter D on Feb 23, 2019
Is the flash can truly solid, and can it be shaved down/reduced t accommodate an afg-2 foregrip adapter? So far nothing will fit as the rail appears to be a slim version and the gas block and flash can prevent the attachment of M-lock accessories.
Andrew T on Feb 20, 2019
Will this work on my PSA AR15 Complete MOE EPT SBA3 Lower?
Jerry b on Feb 6, 2019
Is the gas tube supposed to be going all the way through the gas block? That’s how mine arrived today..
Johnny A on Feb 2, 2019

100% Satisfied Customer!! Every bit as As reliable as my Armalite
I Recently Purchased the 300 blackout upper along with a AR9 upper. I waited to review till I sent over 1000 rounds through them both. I want to start by saying, I found PSA by accident in searching for a different manufacture. I decided that being the price they were, I didn't have a whole lot to lose being it was half the price of the Brand I was originally interested. I took both to the range after initial cleaning. I mounted the 300 on a Ruger 8500 lower and put a brand new T1 micro sight on out of the box, and installed a 4.6oz spikes buffer( used stock spring) I was already impressed with the craftsmenship, but looks don't mean everything. From the first round out of the rifle this upper reciver worked flawlessly. It was dead on @35yrd with 0 adjustment and stayed there. After break in I've sent close to 1000 rds through this upper and shoot it about 3 times a week, I have been so highly impressed at it's reliability. I'm a 100% satisfied and would recommend to anyone. I am a Proud Palmetto State Arms customer and will be returning for more in the Future. I also purchased a 10.5 AR9 upper and am just as happy with its dependability.

The upper is as accurate and handy as I thought it would be, and the 300 blackout round is really growing on me. My particular upper the handguard slides forward when I take it to the range and shoot it. Creating a gap between the receiver and the handguard. I have torqued it but it continues to slip only about a quarter inch, but it shouldn’t slip at all.
