Is the lower receiver labeled with 9mm or Multi? Only asking if you decide to change the barrel to a 40 S&W.

What home defense HP is best for this pistol and also FMJ for range?
Rick C on Nov 6, 2018
BEST ANSWER: I am running Gold Dot 124 +p through mine. Really good ballistics. Great apartment gun
Does this require certain licensing to own or is it considered a pistol?
Tyler F on Nov 2, 2018
BEST ANSWER: This is considered a pistol. No NFA paperwork.
Can I remove the buffer tube ?
Will the AR9 function without the buffer tube?
Nathan on Nov 3, 2018
BEST ANSWER: Blowback requires an equal and opposite force to counteract the force exerted on the bolt by the fired round. It will not be possible to build a blowback 9mm AR without including a buffer. With the requirement to retain the buffer it will be impossible to build an AR without a buffer tube
Does the stock on the shockwave fully extend out like a standard AR-15 ?
Eddie B on Nov 1, 2018
BEST ANSWER: No, it tightens down where you want it to be
What is the weight of the pistol, without the magazine and ammunition?

I’m going to get one for the wife
Love this rig, it’s a little on the heavy side. I was thinking about lightening it up some but i think it makes it that much more stable a platform.

Great gun
Great entry into a 9mm AR. Out of the box, slapped a Holosun site on it and was driving tacks at 20 feet. Easy to shoot, lightweight, the only drawback is that the supplied mag is pretty cheap.

Perfect. Functions flawless. Have put maybe 200 rounds through it so far. Already recommended to multiple people! Extremely happy with it. Will absolutely be buying another PSA AR as soon as money allows!
