How is he rail attached Does it have a provision to lock in place so it will not turn or move when firing?
Snake on Jul 24, 2018
BEST ANSWER: It is attached with three big screws and two small screws. The three big screws can all be seen in the picture. Only one of the small screws can be seen because the other is on the opposite side. There are alignment ears between the hand guard and upper receiver to prevent the former from rotating. You can see it in the picture. It's the small rectangular piece.

so on that top space where there is no rail, can i still mount a section of mlok or a tape switch?
unicorn on Sep 22, 2018
BEST ANSWER: yes, there is still mlok section
Is the upper assembled?
Levy548 on Nov 17, 2018
BEST ANSWER: Yes, in all pictures where you see parts assembled, they come assembled. If you see parts, as you do in this picture it shows what you are getting. In this case, everything for the pistol except the lower receiver. Assembly required for the lower, but not the upper. I have never found PSA to show something assembled when it comes disassembled.............
Is this gun a semi-auto?
james s on Dec 8, 2018

Is this rifle chambered for both .223 and 5.56 or just 5.56?
John P on Dec 10, 2018

Does this need an to be shipped to an FFL?
Jeff W on Oct 10, 2018
BEST ANSWER: If you live in a state that follows the Bill Of Rights, your good to go - shipped right to your door. It cannot be shipped to Washington, DC, Massachusetts, Connecticut, and several counties in Illinois. In fact, pretty much nothing can be shipped to those “states”, since your government prohibits it. Cannot even be shipped to an FFL.

Christian T on Oct 8, 2018
BEST ANSWER: Yes. I don’t have one but there is nothing preventing you from installing one.

It went together easier than expected then I added the Sig scope. I immediately put 150 rounds through it and it performed flawlessly. Was a little disappointed that the brace arrived with a decent deep scratch/gouge in it. They offered to replace it if I sent it back but I was too eager to build and shoot it so i guess I have to live with it like that.

Every time I buy a new gun from Palmetto I get more and more impressed with the quality of their products. Slight gap between the upper and lower on this one, but nothing a rubber o-ring didn't fix...all in all, i'm VERY happy with this gun!!!

Nice pistol build
Great kit, I ended up changing the rail out because I wanted to put my streamlight tape switch on the top rail. Other then that it has been reliable and well worth the price.

Happy purchase
Great product very lightweight and went together smoothly. Only thing I would suggest is to make sure everything is cleaned and lubed before firing which I guess is a gimme. I did not clean it at first and had a lot of miss fires and feeding issues. After it went through a cleaning it ran smoothly
Top is the 10.5”bottom is the 16”
