Can you screw a suppressor on this barrel, or will it hit the hand guard?
Ray M on Aug 15, 2018
BEST ANSWER: Yes, but I would assume it depends on the suppressor. My Dead Air Ghost 45M fits on the upper using direct threads with no issues and about 2-3mm of clearance in front of the end of the handguard.
Has the head space been checked? Is the upper ready to go?
David F on Aug 20, 2018
BEST ANSWER: Slap it on a lower and you're ready to go.
Why have a pistol length gas block on 16" barrel?
Thomas K on Jul 27, 2018
BEST ANSWER: It's not a pistol length gas block. It is a pistol length gas SYSTEM. This works best with the 300 blackout cartridge but does NOT make it a "pistol" upper
Is the A2 flash hider removable/threaded?
Adam B on Jul 30, 2018
BEST ANSWER: yes. 5/8x24 threads.
Will this upper work on any other lowers???
Michael on Jul 27, 2018
BEST ANSWER: these fit and function on any quality AR15 lower. psa has the pistol gas port dialed in spot on for hornady 110gr or 208gr. the new lightweight rails feels and functions great.
Does anyone know the weight of this complete upper?

Will this fit and work properly on a PSA .556 complete lower that I currently own?
Jerry B on Aug 15, 2018
So basically complete a designated pistol lower set and then add to this and Iā€™m good? Thanks
Saint on Jul 27, 2018
BEST ANSWER: Since this is a 16" does not have to be a pistol lower! Can be a Carbine or Rifle Lower!
I have a smith and Wesson sport 2. Can I just switch out the upper of my AR15 and replace it with this upper to get a higher caliber? Does the CH and BCG need to be change everytime or can they use the same one?
TITUS Y on Aug 5, 2018
BEST ANSWER: yes, 556 and 300 use the same CH, BCG, and mags
Does anyone know if the DPMS G-2 in. 308 Lower will fit this upper since the G-2 can be fitted with other AR15 accessories?
Ronnie on Aug 1, 2018
BEST ANSWER: Absolutely not, this is for ar15 platform only. Mags work too.
Is it over gassed? If so is it possible to replace with an adjustable gas block?
Travis W on Aug 21, 2018
BEST ANSWER: It really depends on what loads you intend to use and if you will be adding a suppresor into the mix. I have not had any issues so far with loads from 110grain to 155grain without a suppressor. It had a failure to eject one time in the very beginning, but so far no malfunctions whatsoever since. I chalked it up to the break in period within the first ten rounds or so, using some odd ball ammo. If you really like to tinker, an adjustable gas block and an assortment of buffer weights can keep you happy. I just dropped this on a decent mil-spec lower and haven't looked back.

BEST ANSWER: Aside from needing to mount it on a complete lower, it is basically complete except for your choice of sights or optics.
Will PSA ever bring this upper back?
Maverick on Oct 22, 2018
BEST ANSWER: I think they should. Its a nice upper.

Bought the upper to replace one that I wore out. Have already cycled 500 rounds through this one and am very pleased with its feel and performance.

Fun and exciting to shoot
The 300 Blackout is just a great firearm to shoot. The trigger was an upgrade, but went the less expensive way, almost a must with its shortness. Have created rounds at 100 yards off sand bags with 3/4 to one inch groups. Just a tad expensive in the round department verses the smaller calibers. But fun gun to shoot and so many possibilities. Great value

Met my expectations
Upper arrived in excellent condition. Have run numerous subsonic and supersonic loads without a single malfunction. Ran everything I fed it; which is what I have come to expect from PSA. WELL DONE.

Buy it
Another great upper at a reasonable price and ready to fire. Groups as good as I can shoot, and I’m not a bad shot. Which goes to say the price is way more than reasonable in comparison to some big names or even high end custom one offs. If you’re an outstanding marksman that could go pro tomorrow then spend more on something else. It’s a very good upper, not gonna make you a better shot. That’s on you. Save your money for good glass. This upper will always send it straight home. Cheap knockoff optics will fail when you need it most. And I know, regardless whether it’s ACOG or ACRAP always put on a set of flip ups. Murphy is alive and well...

Excellent addition to my collection
I ordered this a couple weeks ago and haven't had a chance to use it yet. I ordered it to complete a pistol lower I am working on. I am waiting on a scope for it and plan on doing some shooting this next weekend. I plan on using this upper for deer hunting in 3 weeks. Another quality product from PSA. I'll come back after I get some rounds downrange and give an update.

So far so good. I've got the barrel broke in. It's very accurate. Very small group at 100 yards. I e got absolutely no complaints as of yet. I've put about 500 rounds through this rifle.

Nice piece for the money
Works great and for the money it’s a complete upper hard to beat. Added scope and my lower. Off to the range. Couldn’t be more happy.
