john l on Jul 13, 2018
Could this weapon be modified for LRBHO with a part exchange? If so, what part/modification required?
Patriot_Son on Jul 15, 2018
Is it easy to get your fingers caught in those huge cut-outs in the top portion of that terriblely designed handguard?
Jmmmmmmmm on Jul 13, 2018
BEST ANSWER: Yes it is possible to get even my very large gorilla grip fingers cause in the cut outs occasionally
Can the Shockwave blade be replace by the SBA3?
V L on Jul 12, 2018
BEST ANSWER: Only by replacing the buffer tube. The SBA3 takes (and comes with) a standard milspec buffer tube which is adjustable. The kak tube isn't setup for the adjustable stocks.
Will it take Glock Mags?
SteveK on Jul 12, 2018
BEST ANSWER: Yes it will accept Glock 17, 18, 19, &34 mags for sure, I don’t know about Glock 26 because of its low capacity, it may be too short to lock in place
I have an Osprey 45 suppressor. What are the inner dimensions of the handguard, and will my osprey fit inside the handguard to thread on?
Andrew W on Apr 29, 2018
BEST ANSWER: I have an Omega 45k and it fits very snug. The Osprey 45 has the offset so i do not think it will fit. The flash can that it comes with is 1.2 inch diameter and my Omega 45k has 1.45 inch diameter and barely fits. Good luck.
The KAK buffer tube allows the brace to be fixed at several pre-set positions. Does the PSA tube allow the same adjustments?

Is the PSA AR 9mm capable of firing +P ammo ?

Fine shooter
Purchased one of these to have a platform that would cross-over with my pistol magazines. I have shot 500+ rounds through it and it has performed flawlessly. No malfunctions of any kind. Have ran mostly CCI, B&S, and rem UMC 115gr. The barrel length is a little short, and can effect front grip of firearm. I knew this with purchase and wanted a smaller platform for a backpack style gun. Great purchase like usual from PSA.

Please note this item clearly states it doesn't have a last round hold open option.
