This does come with a complete lower parts kit correct? All it needs is a striped lower?
Chris B on Aug 16, 2018
BEST ANSWER: That is correct.
Will this set up work with subsonic ammunition?
Tater Salad on Aug 19, 2018
BEST ANSWER: Technically yes. It will fire subsonic ammo. The 1 in 7 stabilizes subsonic 200gr plus projectiles better but this will work if you aren't worried about moa accuracy at any sort of distance.
Will any stripped AR-15 lower, like the PSA AR-15 1728 lower, work with this kit?
Wayne W on Aug 17, 2018
BEST ANSWER: Any AR lower will work. Lowers are NOT designated pistol or rifle. They just say multi caliber.
If you live in NYS and have your pistol permit can you have this shipped to your house?

I'm wanting to buy an upper in 300 AAC Blackout.
My question is, which is better for all around use, subsonic and supersonic rounds, the pistol upper or rifle upper??? Thanks
Frank S on Sep 30, 2018
BEST ANSWER: If you are using a suppressor subsonic, if not you won't see enough of a difference for it to matter

Great kit
The quality of this kit was top notch. Shipping time was only a couple days. After building my lower and attaching this upper it was off to the range. After 100 rounds still runs great with no problems. Great price Great kit.

Would definitely buy another one.
Great little package. Gas rings were a tad tight upon arrival, but after couple rounds down the tube its working great. May need to change buffer tho, had some over gas issues

Won’t be sorry!!!
Been wanting a 300 blackout in pistol length for a while. Went on sale and snapped this one up. Couldn’t be happier. Grab one for yourself!!!
Can’t be happy with this build. Paired with an extra PSA I had.  Went together with no problems.

Great for short people! Or for fitting in tight places!
I love this AR pistol! I'm a relatively small framed guy, full sized ARs never felt like a good fit. But this one is perfect, feels like an extension of my arms. I highly recommend buying one of these if a full size just feels a bit unweildy. It's my first experience with 300 Blackout, which just makes so much more sense then 556 out of such a short barrel. So far I love the round, just not the price per shot. But I imagine 300 ammo costs will continue to drop as they have been for several years.
