I have an M&P sport and was wondering if I can just use the lower and bcg and just slap it in this upper? I was also worried about the mid length system with the original buffer which I believe is carbine length?
Sloth on Jul 31, 2019
BEST ANSWER: Yes, you can use any mil-spec upper and lower interchange. As to the buffer, it is a carbine buffer..not carbine length. Carbine buffer refers to the weight of the buffer, carbine being lightest, and should run just fine with a mid-length gas system....mine does.
Is the top section MLOK?
B lee on Jun 14, 2018
BEST ANSWER: 2” before receiver and 2” before end near barrel are picitany the middle of rail is mlok
Does the handguard have a full length picitany rail (like that of "flattop uppers")?
Trygve V on May 30, 2018
BEST ANSWER: No, it has rail extending out from the upper for a little ways and a section at the end for a front sight. It is similar to the Aero precision atlas
Does the handguard have QD mounts in it?
Terry S on Jun 1, 2018
BEST ANSWER: Yes, each side nearest the receiver.
Is the handgaurd smooth, unlike psa other rails that have sharp edges?
Brett on Jul 7, 2018
BEST ANSWER: This rail has very smooth edges
Is that a freefloat handguard? It looks like one but doesn't say it where is does say it in other uppers.
tom d on May 6, 2019
BEST ANSWER: Yes, it is a free float handguard...and the best looking one they offer. QD ports at the receiver and muzzle. Easy to take on and off if you like to tinker with you AR's.
How hot does the handguard get when fired?
Cody T on Oct 20, 2018
BEST ANSWER: I have fired several 30 mags in a row without the forearm getting hot. The barrel another thing- smoking hot!
Does the handguard use a special barrel nut, or does it use the same barrel nut as what PSA's A2 FSB styled uppers?
Martin M on May 10, 2019
BEST ANSWER: Completely different, proprietary barrel nut
Is the forward assist functional? Or is it just for looks?
Wesley on Dec 28, 2018
BEST ANSWER: It is functional. Great upper in my opinion for the price
Is the A2 flash hider pinned or threaded on?
Josh B on Nov 13, 2018
BEST ANSWER: its threaded on.
If you swap it out with something else make sure you put a new crush washer on it.
Does this fit Anderson lowers?
Mason P on May 13, 2019
BEST ANSWER: Any mil spec upper will fill fit a mil spec lower their made to fit any manufacturers Ar parts .the only thing that are different are buffer tubes .
Can this upper shoot .223 as well?
James J on Apr 12, 2019
BEST ANSWER: Yes, you can run .223rem through a 5.56 upper. It’s not recommended to run anything other than .223rem if the rifle is chambered for that specific caliber on the other hand. Plus 5.56nato is a touch less stressful on the wallet too
Does this upper fit any lower mil spec kit?
• J on Dec 8, 2019
BEST ANSWER: Yup. I have three of these on three different Anderson lowers that I built. As with any AR built from scratch (assuming mil-spec) it should all fit together, but some things might be a little tighter from build to build; in this case takedown and pivot pens.
Ultimately it should be fine.
Does this fit the Anderson Lower ? I have and extra one and want to complete it
Mason P on May 13, 2019
BEST ANSWER: Absolutely does fit. I have quite a few PSA uppers on Anderson lowers that I've built. This complete upper is one of my favorites, handguard is nicely finished, no sharp edges.
Is the gas block for this upper adjustable?
Gian G on Dec 27, 2018
BEST ANSWER: No it has a standard gas block
Since it fires the 5.56, is this a Wylde upper?
Mac N on Jul 8, 2019
BEST ANSWER: This barrel is a chambered for 5.56 and is marked 5.56.
Is this a FN barrel?
Paul E on Apr 18, 2019
BEST ANSWER: No. This is a barrel made by PSA. FN barrels are in the Premium line
Can this be had with a 15” m-lock ?
Robert W on Dec 20, 2018
BEST ANSWER: You CAN get a 15" handguard, but not from this listing. You'll have to search PSA for 15" handguards. Or you could buy this and then go buy your own 15" handguard and swap it out.
Is this considered a Premium, Freedom, or PTAC upper?
Cole B on Nov 16, 2018
BEST ANSWER: I purchased this upper a few months back. The barrel on my upper has “Freedom” laser engraved on it along with the caliber and twist rate.
Is this a Freedom upper?
Shaun R on Jul 6, 2018
BEST ANSWER: Yes it’s laser marked
What bolt carrier and handle does it use?
Papa D on Jun 16, 2018
BEST ANSWER: What bolt carrier and (charging) handle do you WANT to use??? This is the beauty of the MIL-SPEC AR platform. EVERY BCG and charging handle will work with this upper...

Penn H on Sep 22, 2019
Two questions. The "A2" profile barrel, is it smaller diameter between receiver and gas block than from gas block to flash hider? What is the MLok handguard made of (extruded, t6 alum., etc?) Thanks

Lightweight and Awesome
This upper is much lighter than all my other rifles. Don't get me wrong, it's not the lightest you can get but for the price, its very nice.

Great upper... Some issues
Very accurate upper. Put about 200 rounds through it and was hitting coke cans from 100 yards away with ease. Noticed afterwards that the hand guard was sliding off! Waiting for an email response now to get it fixed. Hopefully it was just a one time issue where they didn't tighten down the hand guard enough.
