Is the bore of the barrel, the INSIDE of the barrel of this upper, treated with Chrome Moly Nitride??
Harry G on Jul 20, 2018
BEST ANSWER: No, just nitride. The barrel is the Chrome Moly...the treatment is the nitriding, it is both inside and outside.
What's the gas block size?
Nathan on Jul 19, 2018
BEST ANSWER: It has an F marked gas block compatible with detachable carrying handles and back up rear sights. If you are looking to install a free float tube you will have to install a low profile gas block. It is a true carbine length gas tube by the way.
If I bought this along with a complete lower, would this be all I need to have a functional AR?
camss on Jun 16, 2018
BEST ANSWER: or rear sight, mag, and ammo. Go right above and get the ten mags and 300 rds.
Recently purchased this upper. What type of optics or flip sight do you recommend for this rifle?
Raymond H on Aug 13, 2018
BEST ANSWER: I have a mbus open sight on mine which is fine for plinking but I also bought the vortex red dot sold by psa and mounted it for a little more precision A good 3x9x40 is even more precise if you want to be a tack driver it’s a matter of personal preference
will this work with my 5.56 nato stripped lower?
mike m on Nov 25, 2018
BEST ANSWER: Yes it will, but you will have to get a lower build kit or trigger group, takedown pins, bolt and mag release, buffer tube etc.
Is this a “Heavy” Barrel?
John A on Jun 26, 2018
BEST ANSWER: No, description says M4 profile barrel
Can a vertical hand grip be used on this handguard?
ALG on Nov 4, 2018
BEST ANSWER: Out of the box, NO, it cannot. However, Midwest Industries makes rails that are compatible with these hand guards. I bought them and had used them on this model for a while. They make a LONG and a SHORT rail. I believe you can purchase them here.
Can you put a free float quad rail hand guard on this as is ?
Dustin on Dec 21, 2018
BEST ANSWER: No. You would have to remove the front sight and replace the handgaurd aswell for a free floated setup,aswell as a gasblock. I recently did a free float setup on one of these and turned it into dmr setup,and the upper does really well,if you decide to go that route. Hope this helps.
What size quadrail would this take?
James C on May 18, 2018
BEST ANSWER: 6"
Will the MOE EPT LOWER fit this upper?
JTsomers18 on Dec 2, 2018
BEST ANSWER: Will fit any mil-spec lower
Can a vertical hand grip be used on this handguard?
ALG on Nov 4, 2018
BEST ANSWER: Yes, with a rail accessory mount added to bottom of the
hand guard.
Does this use round or triangle handguard caps?
Jacko on Aug 8, 2018
BEST ANSWER: Round
Without any adjustments will it fit a 7" handguard quadrail just fine?
Jedominguez63 on Jul 19, 2018
BEST ANSWER: Yes.. it fit perfect
What kind of mounting Barket can I use to add a foregrip? If I can at all?
JTsomers18 on Dec 7, 2018
BEST ANSWER: This is a standard mil-spec set of hand guards. That doesn’t mean you can’t setup forward grips of whatever kind. I’ve used the Magpul rail sections and bolted them onto these types of rails before. It’s not the best setup but it will hold up to normal use.
I have this setup but I want to change the handgaurd to a 15" tactical one in odg any advice?
Jonathan T on Sep 1, 2018
BEST ANSWER: There are so many options for your fore grip it's not even funny. Some go around your front sight and others require removal of it. As far as I know you can do either with tbis upper. It's Mil Spec.
I'm looking to put Boyd's hardwood furniture on an upper. Will this be an issue? Boyd's says specifically that the triangular front caps will not work with their hand guards.
Layne M on May 24, 2018
BEST ANSWER: This upper receiver has round handguard caps, which are compatible with Boyd's furniture.
What part can I not get shipped to my door??
Richard S on Jan 13, 2019
Will this work on a Tennessee Arms lower receiver?

Great fit with matching lower. Can’t beat the cost for a basic quality AR15.

Great quality tight clearances
Great quality low cost but fit tolerances are tight that's a good thing . I tried firing it before taking it apart and lubing it, NOT recommended. The first round fired but only brought next round 3/4 forward, broke it down and found the bolt carrier group was very tight. Cleaned all parts lubed and ran the charging handle a few times an then ran 200 rounds with no issues. Note to self, clean and lubes all firearms even if new.

Great upper,great price
Great setup for the price. I recently went with a free float handguard and this upper really shines now. I have bought about four of these now. Best bang for the buck. Sorry for the terrible pun. Haha

Absolutely an Awesome upper
I purchased this upper with the lower parts kit and matched it with a Savage MSR 15 lower and the fit was perfect. All I can say is PSA sales nothing but QUALITY and the shipment time for both purchases was fast, 6 days... Thank you PSA....

Top quality, accurate, reliable, and could ask for nothing more. Extremely great value.
PSA never fails on quality. I have this same rifle from them in black and now this OD. Will go for the DE model next after getting the upper for the AR1 A2 lower I bought.

Bought this to add an option to my A1 clone. Much lighter and shoots good. Fits the BCA lower good. Used the Magpul MOE stock kit. It all went together fine. PSA service is top notch.
Bought this to add an option for my A1 clone to make an M4 clone.
With scope.

I will buy another PSA upper.
As good as it gets for the price. PSA outsources high end parts (rumor has it). Such as barrels from FN. Their torture test says it all. This upper will not fail.

Most Bang for the Buck
This will function/perform on par with the myriad of uppers on the market. That being said, there are better looking options if the price of admission is to be ignored
