What is the total weight on this? Thanks!
Grady D on Mar 21, 2019
Does this rail have qd mounts on the opposite end of the barrel?
Christopher H on Sep 10, 2018
BEST ANSWER: QD mounts on both left and right sides closest to the magwell but none out towards the end of the barrel.
Regarding the handguard, does it come with m-lok cutouts on the bottom in addition to the m-lok cutouts on the sides?
Greg E on Jun 25, 2018
BEST ANSWER: Yes it does.. 3- 6 - 9 o'clock position for M-LOK.
Is this a free float rail system?
Christopher H on Sep 10, 2018
BEST ANSWER: Yes, Free floating with M-Lok slots for accessories. Let me know if you have any other questions. I am very happy with this purchase. Fit perfectly on my Tennessee Arms lower. No gaps or wiggle.
Can this barrel shoot 223 rem?
TangoXrayNiner T on Mar 19, 2019
BEST ANSWER: Yes. Anything chambered in 556 NATO can shoot 223 Remington. But not the other way around. 5.56 NATO has a much higher chamber pressure than 223 Remington
Will this fit a smith and Wesson lower?
Mossyoak on Jul 14, 2019
BEST ANSWER: Yes. But with nonmatching brands the finish may not match, and there could be a very slight gap or wobble between recievers. This is a nice upper and a good price, you will enjoy it and feel its a great value.
Is the muzzle device screwed-in/pinned or is it permanently attached? I just want to know if I can replace it down the road. Thank you.
Lee Jameson T on Mar 17, 2019
BEST ANSWER: Nope, threads right off! No pining or anything like that.
Would this fit a delton ar-15 lower?
Tyler S on Oct 16, 2018
BEST ANSWER: Yes. I have a DT sport and it fits nice. No wiggle or jiggle.
Will this PSA upper fit a Bushmaster X-15 lower?
scott c on Jun 18, 2019
BEST ANSWER: It should fit any AR 5.56/.223 lower. 2 pins and it's in. That's what makes owning several AR's fun. They are interchangeable.
Does this have a chrome plated boar?
DoorKicker918 on Oct 6, 2018
BEST ANSWER: Chrome Lining: None

No but just buy a barrel with a chrome lining and replace it one day down the line.

All you have to do is read the specs: And that's BORE by the way.

Mark R on Jun 19, 2018

I'm considering this upper for my next build. With it's mid length gas block, would a carbine length or rifle length buffer spring be best for function? Thanks in advance.
Bradley A on Jul 13, 2019
Is the bolt carrier MPI?
I'm sure it is but I couldn't find it on here.
Adrian X on Jun 11, 2019
Is carrier 8260 or 158? I see the bolt is 158
bill s on Mar 22, 2019
Is this a heavy barrel? I live in Maryland and state law requires rifles to have be heavy barrels.

Can’t go wrong with the price
This is a high quality upper. What a great time to be building AR’s. The price point on these are really unbelievable. I’ve had great success plinking paper, steel and prairie dogs. Accuracy is top notch. I mounted a Sig Romeo 5 from PSA in mine. Great product!

Perfect
I built my AR part by part I had never done that before. This upper is unbelievably light. Add some accessories, iron sights & a RedDot & it becomes an extension of my body. What I have now cannot even be compared to M16A1 & A2 that I used in the military & nuclear security. I love the M-lok system. This is a winner by far.

Good deal for what I paid.
Love everything but the weight. The barrel has a lot of extra metal on it. Got about 400 rounds through it and it loves it all, zero failures. Currently getting 1" @ 100 but I think she could shoot a bit tighter with a fancy trigger. This is a good choice for a durability / reliability build.

Amazing
Amazing upper for the money. The mid length is an awesome system. Very happy. Put about 500 rounds through it the first range session and got 1 failure to feed. Went home and cleaned and oiled it, put about another 1500 rounds through it since then with zero malfunctions. Really happy with it.
