What is the overall length?
Kevin on Jun 14, 2018
Does this particular pistol have a last round bolt hold open feature?
Kevin on Jun 14, 2018
What must one do/get to fit a 1/2x28 threaded can on it? Adapter?
Jeremy N on Jun 18, 2018
BEST ANSWER: An adapter might be best. A lot of after market barrels come with the standard 1/2x28 thread though.
does this gun require a SBR stamp?
beanerdee1! on Jun 29, 2018
BEST ANSWER: I am fairly sure it does not, as it is technically a pistol. Just make sure that you don't put any feature on the pistol that will redesign the pistol into a SBR
Can you remove the rear weight from the bolt carrier group (punch out roll pin) to install a Law Tactical folding adapter? Thanks!
Stephen S on Jun 21, 2018
BEST ANSWER: Not with the provided bolt, I bought a different bolt and was able to do this though.
which glock magazines fit this gun?
soconyjoe on Jun 12, 2018
BEST ANSWER: Glock 19 and Glock 17 mags work for sure. I have not tried Glock 26 which are quite short. The ETS 33 round clear mags work well also.
What type of “blem” can I expect?
SharpKnife on Jun 12, 2018
BEST ANSWER: I had to look to find the blemish... on mine it was an "oddity" in the lower about a centimeter in diameter that's hidden when the upper is in place. I'm sure each one is different, but I was happy with mine.
Can you fit a silencerco hybrid suppressor under the handgaurd? It appears the threads are behind the front of the handguard.
Micah A on Aug 19, 2018
BEST ANSWER: I live in the draconian state of illinois and cannot purchase or possess a suppressor so I cannot help with this question with first hand knowledge. Looking at my pistol I and inclined to say that you would not be able to fit the suppressor into the muzzle with the standard handguard attached.
How well will this work supressed?
Ryan T on Aug 18, 2018
BEST ANSWER: The barrel in fluted within inside of the hand guard. Don’t think a suppressorwould fit with the length of barrel. Go with a longer barrel that extends past the hand guard
What kind of accuracy are you seeing out of it?
J.R. F on Jul 17, 2018
BEST ANSWER: I have a Bushnell TRS-25 on mine, it makes pretty tight groups in the range I work in, 25 to 40 feet.
Does anyone using supresor on this pistol? Advice please... Thanks
Ibrahin D on Jul 17, 2018
BEST ANSWER: I've used one on mine. It works well but does extend the overall length. I'm not going to mount mine due to the way I want to use the pistol.
What buffer and spring are used in this combo?
William H on Apr 21, 2018
BEST ANSWER: KAK Shockwave Blade brace and buffer tube. Was so impressed with it on the PSA 9 mm pistol that I bought another set for an AR pistol build also.
Does this gun require the buffer tube to function or is it to hold the brace only?
Terry B on Jun 28, 2018
BEST ANSWER: Yes it does require the buffer tube.

Very impressive quality
I am very impressed with the build quality of this little beast. The use of a Magpul grip and flashcan just make it even better. It points exceptionally well and is crying out for all manner of bolt on accessories from red dots to laser/light combos. It's a great plinker and home defense system.
Worried about buying a "blem" item? Don't; I had to search diligently to find what might be a blemish - a tiny mark the size of a small gnat's littlest toe.
Overall this - and PSA - gets 6 stars.

If you are looking for a 9mm ar pistol, get this one
What a magnificent deal. Functions flawlessly, shoots straight, awesome price. Would be *PERFECT* IF it had a bolt catch. But considering, it's pretty hard to beat

If there is a blem it is small. 200 rounds and no malfunction. Haven't tried ETS mag. Glock magpul and Promag works great.

Great gun that's nearly perfect - almost
Great quality weapon, solidly built, at a great price. It's extremely accurate. These pistol braces are a great alternative to paying the government to attach an actual stock to make an SBR.
But it could be improved: The Shockwave brace is a hard, narrow piece of plastic that hurts when the weapon is shoulder fired, and this gun kicks pretty hard for 9mm. The SB tactical SOB brace is a much better choice. The forward assist is literally useless, and doesn't need to be there.Lack of a last round hold open is annoying. Other AR-9's have it, why not this one ? Handguard looks good, but is unneccesary, as is the muzzle thingy. They just add weight.

Absolutely the most fun gun I own!
This was exactly as described. A tiny little mark on the Picatinny rail. Doesn’t matter at all. Since this isn’t a beauty competition. This is just a cool gun to own and shoot. If you have ever wanted one, pick it up, don’t wait. About 300 rounds through it, no issues.
