Wouldn't the barrel profile be considered a heavy barrel for this upper? (Maryland compliant question)
Hayden O on Apr 21, 2018
I'm waiting for this to come in. However I'd like to buy a quad rail in stead for the plastic, what drop in quad rail will fit this upper?
Brinks on Apr 26, 2018
BEST ANSWER: knights armament and midwest industries both offer drop-in replacements.
legal In California because of shorter than 16" barrel?
Jason T on Oct 5, 2018
BEST ANSWER: The barrel measures 16" in all states.
Does the barrel profile stay the same diameter throughout, or is it thinner under the handguards ?
Arthur F on Aug 5, 2018
BEST ANSWER: I have several of these. The A2 profile should be the same under the handguard. The government cut is a smaller diameter under the guards. It is also lighter for field carry. Mine are the same .750 under the guard. HBAR is heavier under the guard.
Could this upper take a different hand guard?
Chris on Jul 7, 2018
BEST ANSWER: While mid-length handguards (8.5") are not as prevalent as carbine length (7") equivalents, there is nothing unusual about this setup that would prevent a drop-in replacement. There are also a few handguards that call for the triangular hand guard retainer - those will not work here.

If you want to free float it, you'll just need proper tools to remove the delta ring, barrel nut and front sight block.
Us this upper compatible with the .223 rounds?
Chris on Jul 6, 2018
One person said triangle cap, other said round cap for hand guard. Which one does it have ?
clay p on Aug 21, 2018
BEST ANSWER: It has a triangle end cap...I just replaced the hand guard recently
round or triangle front handguard retaining cap?
EspoMan E on Jun 15, 2018
BEST ANSWER: It’s a triangle retaining cap.
Does this have built in sights or do you need to buy optics in addition?
Kenny A on Nov 23, 2018
BEST ANSWER: You’ll need a rear sight at the least. The rail on the upper receiver will fit an MBUS rear sight perfectly. And almost any scope mount that fits a picattiny rail will also work.
How accurate is this upper with .223 ammo?
Kyle R on Nov 14, 2018
BEST ANSWER: I didn’t notice much of a difference, I’ve used all types of ammo. This is a wonderful upper and hasn’t had any malfunctions even with steel case. But to answer your question it’s pretty dead on accurate.
What color is the hand guard ?
Thad007 on Nov 19, 2018
BEST ANSWER: Black -ish
Does the bolt carrier have a logo?
James R on Nov 25, 2018
Does this upper front sight come zeroed?
AlexanderG on Nov 30, 2018
What length is the hand guard ? I want to do a drop in quad rail any suggestions ?
Chris w on Nov 22, 2018
Would a Troy industries 9 inch mid length quad rail fit? The majority of mid length rails I’ve found have been off by half an inch or so would that matter?
Calvin840 on Nov 20, 2018
I see the question of heavy barrel classification was asked but not this barrel legal to own in a heavy barrel state such as maryland?

Well Worth It!
Bought one of these as a BLEM a few months ago, and just got around to putting a lower underneath it. Only BLEM I could find was some small marks on the barrel. They cleaned-up with some REM-Oil. This is a HBAR Carbine (right up to the flash suppressor), and has an F FSB, triangle front hand guard fixture and has a mid length gas system. With a collapsible stock it seemed over-gassed. I threw on an A1 stock w/ rifle buffer & spring and it calmed down. With a MILSURP carry handle it zeroed in 7 rounds.(PPU 5.56, 55gr FMJBT). More accurate than I thought it would be. I'm happy!

Another great value from PSA
Excellent quality for the price, and mid length gas system on a 16 inch carbine is a great way to go. I am tall and like both the shooting characteristics and the ergonomic of these because I can get my left hand farther forward than a carbine. This configuration increases the distance between sights over a carbine length gas system, also. If that weren't enough, an A2/M16 bayonet can be used. Not the case with a carbine length. Skip the carbine, do the middy. The PSA carry handle goes well with this upper. My example was well made and had no quality issues. BCG was fine. All the staking looked good. Shoots well, no issues over a Colt M4 lower and a 80% carbine lower. This is not an issue of if. This is an issue of how many. I say... 87.

Had an issue, but PSA took care of it.
I've bought several of these. The last one I purchased had an issue with the front sight being off. It took 20 clicks left of center to be zeroed. I contacted PSA, they sent a return label, two weeks later it was on my doorstep. Took it back out and it was only off 5 clicks which is just fine. In my opinion 10 clicks in either direction is acceptable.

Great products! Great AMERICANS!
I am highly pleased and i HIGHLY recommend doing business with PSA. My order was delivered on time and it runs great! So far I've put about 1000 rounds through it NOT ONE ff, fe or ANY issues whatsoever. The fit and finish is EXCELLENT and exactly as advertised. This is my 1st ar 15 im mainly an ak guy but ive been wanting one for awhile, i looked at what PSA had to offer, their prices, barrel material, upper material and everything was up to par. I really appreciate what the GOOD FOLKS at PSA have done, when it comes to offering a product to folks like a me on a tight budget. I purchased a mid length upper with BCG and charging handle for 239 SHIPPED and o e of their classic COMPLETE LOWERS for 129 shipped, so total i paid 370$ minus the transfer fee of 25$!!!!! 370$ for a COMPLETE RIFLE, man you cant beat that with a stick! Would i order from PSA again🤔......HELL YEA ....should YOU order from don't even think about JUST.DO.IT. See what i did there😁 Seriously in all candor these are great products that Americans can afford without going broke and still get a QUALITY product that will pass the mustard. You guys take care.
