Can you use a suppressor with this pistol kit?
Jared P on Mar 4, 2019
BEST ANSWER: Absolutely. Subsonic ammunition is rare and unreliable for 5.56 but supersonic runs great through my suppressor. I have the same upper for 300BO and run subsonic through it...very quiet.
If I were to purchase this, would the only thing needed to complete the build be a stripped lower receiver? Or would there be other parts to out source to complete the kit?
Jayson u on Dec 27, 2018
BEST ANSWER: You only need a stripped lower and you would want to add some kind of optic or sights
What is the OAL with brace fully extended?
michael c on Apr 19, 2019
BEST ANSWER: The overall length with the arm brace fully extended is 29" (collapsed is 26-38"). This was my first build an overall I'm very happy with it and it shoots great but the arm brace leaves much to be desired.
Would I need a permit upon pick up at the FFL dealership?
Coty W on Jan 3, 2019
BEST ANSWER: This parts kit does not include the serialized lower receiver, so it does NOT need to be shipped to a FFL holder. It can be shipped directly to your home. You will just need a AR15 lower receiver of your choice and sights or optics to complete this kit. Apart from that, it's your responsibility to check with local authorities BEFORE purchasing anything to see if any permits are required in your area.

I like it
Ran a few hundred round through it..... Only took it out to 200 yards, but what more do you need from a pistol..... I'll get another.

Really great! But keep in mind were your mounting extra grips on the rail
Good! Would recamend for my younger sister! I am thinking of getting her one for her next birthday. It's a great design and a solid upper for my aero precision lower receiver however if your looking at putting any foregrip, angle grip, or hand stop on the furthest forward point keep in mind the m-loc will not fully seat with how the gas block Is located on the barrel and the rail.
Overall great quality for the price and very comfortable size for an ar pistol

Definitely pleased with the kit, as well as the others I've built. The organization of parts eases assembly and the quality of the parts makes for a nice, consistent firearm. Now I just need to decide what to build next.

Wifey absolutely loves it
Anniversary present for the wifey.

Everything went together well other than the buffer. ( it came w/o a roll pin)

Customer service shipped a replacement buffer ASAP.

used a buffer from a carbine to road test it. Ran flawlessly.
One of these days she might let other people shoot it....

Really good after cleaning!
Received this on Friday put it together yesterday and put 200 rounds through it. At first it had trouble feeding rounds and bolt kept not holding back after last round but after taking it apart and cleaning everything and lubed it up it worked flawlessly. So I recommend cleiand and living before firing much better results. The guns very light and looks awesome put together with Anderson receiver.
