BEST ANSWER: 6061 offers excellent corrosion resistance when exposed to atmosphere and seawater. 7075 aluminum alloy is perfect for applications where high strength is essential and good corrosion resistance is less important. 7075 is one of the strongest aluminum alloys available
Can a different muzzle device be put on this upper? It seems the barrel is shorter than the hand guard making it impossible to run a can.
Chris M on Mar 11, 2019
BEST ANSWER: You can run a can as long as the can's outer diameter is smaller than the rail's 1 1/4in inner diameter. The flask can just screw's off and other muzzle devices can be inserted into the rail and screwed on as long as the fit within the 1 1/4 inner rail diameter.
I recently purchased AR15 lower Magpul CTR edition with sole purpose to replace the stock and add a buffer tube and/or add an SB tactical brace. Can I legally purchase this upper if my goal was to always build an AR pistol? Live in Florida. Thanks in advanced.
dhoang850 on Mar 11, 2019
BEST ANSWER: Doesn't matter what your "goal" was according to the ATF, The lower you purchase HAS to be a PISTOL LOWER NOT RIFLE and classified as one on your paperwork you filled out on your FFL. If it was classified as a rifle then no you cannot just add a pistol brace, a shorter barrel and call it a pistol without it becoming a SBR and requiring a tax stamp. The easiest way to always remember is that to run shorter barrels and make those modifications it has to first start as a PISTOL from the manufacturer. Im in Florida as well.
What is the rail inner diameter?
Thomas S on Mar 16, 2019
BEST ANSWER: 1 1/4in inner
1 3/8 is the diameter of the flash can
Measured with tape so may not be 100% exact
What is the rail inner diameter?
Thomas S on Mar 16, 2019
BEST ANSWER: Using a tape measure (couldn't find my digital calipers) it eyeballs out to just over a 1.5" I.D.
Normal AR15 Pistol lower receiver will work right? thinking of putting with my ,,psa-snek-15tm-ar-15-stripped-lower-receiver...1st time pistol builder here
Robert D on Mar 6, 2019
BEST ANSWER: Do not put this on "ANY" AR lower as the other comment suggests! You can add a rifle length upper onto an AR pistol Lower but not in reverse. Otherwise you are getting into an SBR and need paperwork if you don't want the ATF paying you a visit. Just a friendly PSA (Public Service Announcement).
Just ordered PSA AR15 Complete MOE EPT SBA3 Lower - xxx5448150 (AR Pistol complete lower with adjustable brace), this should run well together without any issues right???
Rasheem G on Mar 16, 2019
BEST ANSWER: That is correct.
Is this a complete upper? So to make a full AR pistol, all I would need to purchase is a complete lower ?
Damian on Mar 15, 2019
BEST ANSWER: Yes it is and you are correct.
Will Magpul MBUS front and rear sights work on this Rail?
john t on Jul 24, 2019
BEST ANSWER: I don’t see why not, I have had several different risers, scope mounts and flashlight mounts on mine. I don’t have any MBUS sights, but I am 99.9% sure they would work fine.
Will it fit on Smith and Wesson M&P lower?
Dennis B on Jun 2, 2019
BEST ANSWER: Yes sir. I have 3 of these and they fit on everything I’ve thrown at it. Realize one thing, if it’s tight, don’t worry, it may be a slight tolerance stacking. But I ran this on my M&P lower yesterday without any issue.
Do I need to get the SBR tax stamp before purchase for my build,if not,do I need it sent to my FFL dealer?
Leonard P on Jul 14, 2019
BEST ANSWER: Hello,

No, you do not need an Tax Stamp to purchase this. It will also ship directly to you, no need for an FFL. Please be aware of all laws and regulations before assembly.

Fun For What It Is
Fun to shoot, points very quickly. No F.TF. or F.T.E. after 300 rounds. Currently waiting for my 10 1/2" so I may run my can. Will review it after it arrives.

PSA 8.5" Pistol-Length 5.56 NATO 1/7 Nitride 10.5" Lightweight M-Lok Upper
My first AR Pistol, got it for my birthday and built it with Anderson’s lower. Love the way it looks and shoots for a budget AR.

Great and accurate
Came as offered, everything included for upper. After assembly and mounting a 3x Sig optic was able to shoot a 1.5 inch group @ 100. Very satisfied even after 3 months. No problems at all.

Love the gun, next will be a breakdown barrel kit for an even smaller package....
So for it's a great little weekend fun machine, I have a red dot and flip up Magpul MBus sights, a Law Tactical Folding Brace, a mini green laser, and I decided to order a few 20 round mags as they look better than my 30 or 40 round mags, but I've got plenty of those if I need some...
I installed rubber inserts on the barrel shroud for better grip and heat protection for my hand.
I inlayed 24 carat gold leaf acrylic paint in all the engravings/stamped lettering

perfect pistol
great budget upper. went on a pistol lower with a stabilizer blade, laser, and light. what a great gun this has made. touches plates at 100 yds. make sure and have her really oily when you take her out the first time to make sure nothing is dry. other than that, pew pew.
perfect fit for my pistol lower. out of stock now so i guess, you snooze, you lose. jump on em fast.

Great price for exceptional quality.
Works as advertised. Besides from a couple of tooling marks and scuffs the overall quality is great. I managed to get groups no larger than one inch at 50 yards. Shipped the next day and arrived three days after I placed my order. Overall great experience with psa very happy with my purchase.
