Can this be shipped to a PO Box?
Don S on May 23, 2018
BEST ANSWER: NO - NOT USUALLY HAVE IT SENT TO A GOOD FRIENDS HOUSE
Is this barrel stainless steel?
Singh on Jun 13, 2018
BEST ANSWER: Yes, it is. I have also found it to be VERY ACCURATE,with some of my reloads shooting sub moa out to 200 yds
What kind of rifling does it have? Button rifling?
Dennis M on Apr 28, 2018
BEST ANSWER: I believe it is button rifled, but only the mfg would know for sure.
chambered in .223 will it except the 5.56 round ?
george n on Jun 16, 2018
BEST ANSWER: It's the .223 Wylde barrel which will accept both .223 and 5.56. I've ran about 100 rounds of .223 and about 300 rounds of 5.56 through mine no problem
Does psa make the barrel?
Dennis M on Apr 28, 2018
BEST ANSWER: It is marked PSA, as far as if they manufacture it is unknown to me
Is the flash hider removable or is it put on with Permtex red or Loc-tite red?
Merrell M on Sep 10, 2018
BEST ANSWER: No thread locker but it is tight
Is this barrel as accurate as a chrome lined barrel?
Stan W on Jul 3, 2018
BEST ANSWER: I OWN MANY AR'S. EACH HAS A SPECIFIC PURPOSE FROM CLOSE RANGE FAST SHOOTING TO LONG RANGE AND ACCURATE. THIS BARREL IS A VERY ACCURATE LONG RANGE BARREL OUT OF THE BOX. THERE WAS NO NEED TO BREAK IN. ITS A GREAT ALL AROUND CHOICE IN MY OPINION. CHOME LINED BARREL MAY OUT LAST A STAINLESS ONE BY A FEW THOUSAND ROUNDS, BUT OTHER THAN THAT IT IS AN EXCELLENT DEAL
How does a fore end grip attach to the bottom of the hand guard ?
James Z on Jun 19, 2018
BEST ANSWER: I got a MOE picatinney Rail and mounted that to the bottom. You will need to put it far enough back to where you can get it past the gas block but it is still far enough for what you are looking to do.
Gas block adjustable or able to be swapped for an adjustable?
zeke b on Aug 16, 2018
BEST ANSWER: Non adjustable gas block. It honestly isn’t necessarily it functions well if you do want to change it out it’s simple to change out though
How is steel ammo work?
Singh on Jun 16, 2018
BEST ANSWER: work well with steel ammo. not a problem
Is the gas system dimpled on the complete upper?
Larry S on Jul 17, 2019
BEST ANSWER: The barrel has no dimples.
Would this work with a piston driven aftermarket kit like the Adams Arms standard rifle kit? Not a fan of direct impingement.
The Grill Segeant on Jun 19, 2019
BEST ANSWER: Looks like you would need the P-series kit from Adams for the micro mini gas block. Might be worth a call to them to see if the micro gas block will not interfere with the hand guard. Old saying "Measure twice, cut once"
Is there a sling attachment? If not, what would be required to do so?
ZombieHorde on Jul 9, 2018
BEST ANSWER: It has QD sling attachment points on both sides right where the barrel starts.
This is a question for PSA Technical Staff. What manufacturer makes the barrel for this upper? What type rifling does it have?

Love the concept, but the gas system isn't working out for me
I do like this upper overall. For me, it shoots 1 MOA with ammo it likes and 2.5 MOA with ammo it doesn't. I'm running a 3.5 lb. CMC trigger and a Primary Arms 1-8 ACSS scope, and this is about what I expected and is perfectly acceptable.

My problem is with the gas block; it simply won't cycle more than 2 out of every 10 rounds reliably unless I'm running it suppresse. When I'm running my Silencerco Saker 762 (still waiting for my 556 version's stamp to clear), it functions flawlessly.

My rifle is simply under-gassed without the added back pressure the suppressor offers. I've read the reviews, and it seems a few others might be having this same issue, but the vast majority seem to be working fine. I guess that I just got "lucky"...

Unfortunately, I didn't shoot it unsuppressed for the first 300 or so rounds, and I've now got it set up the way I want it and don't want to blow it apart and send it back. My only other options appear to be (1)installing an adjustable gas block or (2)only shooting it suppressed.

So, I'm frustrated that mine has this issue, but I expect 19 out of 20 leave PSA just fine.

use good ammo
I bought some ammo from a local farm supply. 4 different brands. Mostly because I did not have dies yet for reloading and it was an easy way to get some brass. Bought about a 100 rounds. I was shooting 6" groups at 100 yards. Whats going on here? Bad barrel? Nope bad ammo. My reloads 62 gr. hornady fmj-bt, 26gr varget. Under an inch! Needless to say , good enough for me. I'm pleased.

Awesome upper!!
This upper is nothing short of AWESOME. Extremely tight, dime size, grouping at 100 yards. I figured just for fun I would see how it shot at 300 yards. With no scope adjustments, I held one mil-dot high and shooting off my deck railing and a porch chair and was hitting an eight inch metal plate consistently. No doubt I could get a respectable group if I was shooting from a bench rest. Surprised the hell out of me. VERY HAPPY with this purchase.
