If i take off the psa flash can off Is it possible to fit a suppressor inside the handrail?
Dillan C on Apr 30, 2018
BEST ANSWER: If you have a VERY small diameter suppressor, then yes. Otherwise no. This wouldn't work for my can, but I trimmed the handrail back and mounted the flash suppressor that my can mounts to and used it until I can get a proper handrail.
Are the parts on this upper the ''premium'' ones or standard?
Teej1 on May 21, 2018
BEST ANSWER: The parts are close to premium. But for the money, you are receiving premium parts for the low cost.
Does it come fully assembled and is all I need a complete lower?
Mikael on Jun 5, 2018
BEST ANSWER: Yes the upper is fully assembled. You will have to install the mbus sights but this only requires a flathead screwdriver. Naturally I would remove the bcg and charging handle, then clean and oil everything, and reassemble. Best of luck.
Will an A2 flash suppressor work on this setup?
MStewart on May 1, 2018
BEST ANSWER: I believe so. I own this upper and I would say the flash can is excellent. Maybe you have a good reason to want an A2 so i will say you need to know if the can is pinned on and the threading on the barrel. I do not have any good input on those two. I do believe PSA has the same upper with an A2 and it is cheaper.
Would a Kineti-Tech Blast Shield work here? If not with the included flash can, then with the Kineti-Tech muzzle brake? Would there be enough clearance?
Paul R on Apr 30, 2018
BEST ANSWER: Probably not. I'm,looking to change the hangars so u can do a Smith vortex
What kind of lower should I buy for this?
Nelson I on May 21, 2018
BEST ANSWER: If you want the most cost effective lower that is extreme in quality, get an Aero lower. One step down (in my opinion) but still excellent for the price is Anderson. You can step up in price and style from the Aero and equal in quality is Spikes Tactical. When you get to the premium brand names that do not make in house, they are typically made by Aero and they stamp the premium name brand on the lower.
Can anyone who owns this handguard tell me what the I.D. of it is? Thanks in advance.
Matthew W on May 2, 2018
BEST ANSWER: The hand guard is a close fit on the flash can. Flash can measures 1.2 inches.
Will this fit an SW m&p sport 2? Drop in.
Winner on Aug 16, 2018
BEST ANSWER: Yes, but having a 10.5” barrel will require a pistol brace unless you have a tax stamp
Does anybody know if a Saker 5.56 can will fit with this rail? Thanks!
Ghost on May 16, 2018
BEST ANSWER: The opening on this Mlok is about 1.5 inches. The Saker being 1.5 inches in diameter I’d have to say yes it will fit and if it didn’t the slightest I mean slightest bit of removal of material around the inside of the hand guard might be necessary and we are talking millimeters or less. But if I were a betting man I would say it would fit and would fit nicely. Hope it helps.
With the recessed muzzle device, does the handguard get hotter? Also hows the psa one at directing thing forward, is a KAK slimline worth it?
Paul R on May 14, 2018
BEST ANSWER: I put a hand stop and handrail covers to protect from the heat. PSA device is nice, works as described!
Will this upper fit on my POF Renegade+?
Doug P on Aug 7, 2018
I'm building an ar pistol with this upper, I'm gonna use a mil spec buffer tube, what weight buffer should I buy to get the best performance out of this upper?
Austin G on May 23, 2018
What is the torque specs on the 2 bolts holding the rail on?

Great upper!!!
This is my first PSA AR-15 related product purchase. I purchased this upper with a PSA pistol lower. Shot for the first time yesterday. It ran perfect. Very well made and like everything about it thus far, granted I just got it. I am running just the back up sights and is accurate enough for intended purpose for the time being. I like the looks of the flash can. It may be louder than a 16 inch but I cant say that for certain, it seems to do what it is designed to do and I didnt notice it being louder than my other ar's while using hearing protection. The only complaint I have is one of the qd sling sockets is defective. I stole a magpul rsa from another rifle so I could attach my sling. Great product. If the qd sling point was not defective I would give 5 stars

More than expected
I ordered this to finish a build our of spare parts I had laying around to make a truck gun to drag around. I was expecting a long wait from what I was told about Palmetto but five days later it was delivered excellent work Palmetto. I took this out to see what it would do, I wanted something that would be easy to use in a truck and be accurate at 50m and when I got this sighted in I could ring a 6 inch plate at 100m every time and so far I have put about 550 rounds through it without a hiccup. Way more than I expected and I highly recommend it.

Neck breaker.
Paired with an Anderson arms mil spec and a SB3 tac brace and this thing has quickly turned into a neck breaker at the range. Stands out from the crowd and runs beautifully.
SB3 + Anderson Punisher + The Boom. Vortex on top.
