Why advertising clearance It's out of stock?
Henry Q on Jun 21, 2018
Is the front sight removable?
Michael M on Jul 30, 2018
BEST ANSWER: The front sight post is also the gas block. So yes, but in order for the rifle to function you'll need a new gas block. Though, if you're asking this question it's best to leave it to a professional gunsmith.
I have a 6.8 SPC, can I just buy this upper and convert to 5.56?
xrayjuan on Apr 29, 2018
BEST ANSWER: Yes you can.
This 5.56 only or will it handle.223?
Larry on Dec 18, 2018
BEST ANSWER: Any chamber/barrel marked 5.56 can generally run .223 with no issues. .223 marked chambers/barrels should not use 5.56, the pressure produced by the cartridge exceeds the pressure that the .223 chamber/barrels are rated for.
How long is the hand guard?
Ricross on Jul 4, 2018
BEST ANSWER: Carbine length hand guard 7 inches long.
Does the upper come with rear sight?
Wayne F on Apr 29, 2018
BEST ANSWER: No. It comes exactly as pictured
What do I need to complete this?
Ajt02 on Dec 9, 2018
BEST ANSWER: It's a complete upper receiver. You will need a fully assembled lower receiver to make it a functioning rifle. You will also need some sort of optic to aim your rifle. At the minimum this would be a rear peep sight. The upper receiver already has a front post sight installed.
what is the attachment clip looking thing on the bottom of the front sight, not the strap ring, the other thing?
Sean P on Jan 18, 2019
BEST ANSWER: The only other attachment I can see on the bottom of the front sight is the bayonet mount.
Does it come with T-Marks on the Upper Receiver ??
James S on Jul 23, 2018
BEST ANSWER: Yes, this upper comes with T-marks.
Can the A2 flash hidder be unthreaded and removed ?
Alfaec S on Jan 27, 2019
BEST ANSWER: Yes the barrel is the legal length without the flash hider. The threads are standard for 5.55
If I have a complete AR15 lower, I can just put this on and it's ready to go?
Mike V on Feb 27, 2019
BEST ANSWER: No, you're going to need either a rear sight or optical sight. This upper does have a front sight.

Also, I don't recall if this product package came with a magazine, if not, you'll need a magazine or two. Or three. Personally, I would recommend at least ten.
This item is Compatible with the PSA A.R. 15 classic lower am I right?
Keith S on Dec 10, 2018
BEST ANSWER: Yes, this item is definitely compatible with PSA AR15 classic lower.

Michael J on Dec 6, 2018

Is this barrel shiny blue or parkerized finish? Thanks and have a good day !!!
Sniper on Jan 16, 2019
BEST ANSWER: It is not "blue" or shiny. Couldn't tell you if it's actually "parkerized" or not, but it is black and non-reflective.....Cliff
Can the Calm shell be replaced with a M-LOK?
Andrew J on Feb 27, 2019
BEST ANSWER: I have not had to replace that but I can't see why it couldn't be replaced
Is the barrel also HP/MPI?
John D on Feb 18, 2019
BEST ANSWER: These barrels are not MPI or hammer forged machine gun steel. They are NOT chrome lined either. PSA makes and sells uppers with the higher quality barrels and will state what they are in the captions when you open them for the details.

I have built scores of them in both configurations. About the only real advantage of the MPI hammer forged machine gun steel chrome lined barrels are not having to clean them after every outing. If you are just target practicing and such no real need for the top shelf barrels, but it is nice to be able to put them away after a long day at the range without a good cleaning.......Cliff
Does this barrel have vanadium? It says it does in the paragraph but not the listed specs above.
Kelvin K on Jan 15, 2019
BEST ANSWER: I bought one of these, I have been happy with it. I would contact PSA and ask if you are concerned.
Does it come in 300 Blackout ?
Jay M on Dec 6, 2018
BEST ANSWER: There are 300AAC uppers on the site, some that even resemble this one. But this upper is what it is.
The BCG on this upper calls out full auto, my lower receiver is obviously a semi auto, will this be an issue?
Iceman on Dec 3, 2018
BEST ANSWER: No. It will work just fine.
When will these be back in stock?
NickKHecht on Sep 6, 2018

No Better Value for Quality and Price
I shopped around, a lot. I can save you a bunch of time, just buy this upper. There are about ZERO complete uppers at this price point with these features, including the 1 in 7 twist.
If you plan on buying cheap 55 grain rounds, you can find a few uppers at this price with 1/9 rifling. Right...
Snapped-in firm to my polymer 80% lower. Range time yielded good groups during break-in, with one failure to feed from the new magazines.
I just wish their 20" barreled upper wasn't $100 more. But for a 16" it performs well.

Cheap but reliable
first time out it disappointed. After some oil and cleaning, it fires reliably. The only downfall is huge air gaps in the handguard that makes it feel and look dollar store... other than that it’s a good kit

This is my 1st PSA upper. Lots of scratches and rough tool marks. The dust cover looked scratched. I checked to make sure I didn't accidentally order a blemished upper, but that wasn't the case. I tried to ignore it but I can't...There are also no T-marks on the top rail... I heard so many great reviews but I must say, I'm a little disappointed at the quality control of the finish.. I'd like to replace it but PSA shipping is verrry slooow at times.
