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.
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.
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
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?
A G 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
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?
A G 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
Without any adjustments will it fit a 7" handguard quadrail just fine?
Jedominguez63 on Jul 19, 2018
BEST ANSWER: Yes.. it fit perfect
Will this fit the PSA Blackhawk lower?
Chris A on Mar 14, 2019
BEST ANSWER: Most likely all ar 15 lowers are built on same mil spec's.
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.
Will this upper work the the complete classic lower 7244?
Brandon C on Mar 13, 2019
BEST ANSWER: Yes. Works great for mine and very comfortable to fire. Just snap together and hit the range
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?

Can’t beat it
Bought this with matching lower, $350 total invested. Thats getting a .223/5.56 at a .22lr price. This will be my little fun beater than can be tossed in the truck and I won’t worry about keeping it in mint condition like I do most of my other guns. Bullet hits the target and never had a cycling problem so what more can you ask for?

Buy now, don’t put it off
I was looking to complete a long over due build.
I had purchased a Cobray 37 mm launcher about 20 years ago and never mounted it on a weapon.
I saw this deal at PSA and finally finished the project
