If I purchase this with a complete lower, is that all I need for a pistol? Also, does the lower have to be designated as a pistol?
Davud V on Sep 21, 2018
BEST ANSWER: If you're not building one then make sure you purchase a designated pistol built lower only (ie pistol brace) and do some research as to what is and isn't allowed on a pistol. You're treading a fine line into NFA short barrel rifle territory so tread lightly so the ATF doesn't come knocking. Length, weight and accessories will tip the scales as well as putting a short barrel upper on a rifle designated lower will also turn your rifle into an SBR. Be careful!
In regards to this specific upper, u need a BCG and charging handle. Any charging handle will do but stick with a full auto BCG not a lightweight model. You'll need the weight to help with cycling such a short gas system.
What complete lower do you recommend for this upper?

Will this fit on a lower bthat will come off of a 556 upper that is not pistol length?
John C on Sep 23, 2018
BEST ANSWER: It must go on a lower bought new as a pistol lower or else it’s an SBR which needs ATF form/tax stamp. Careful!
What is the width and length of the Flash can?
Fabian R on Oct 25, 2018
BEST ANSWER: 1.2” diameter, 3.5” length.
What is the recommended buffer for this upper, I was told a H2 ?
Chris L on Jan 23, 2019
BEST ANSWER: That’s what I used in mine and it works great. I actually did the Giessle braided buffer spring and H2 buffer that comes with it. Worked extremely well. Very smooth cycling, zero issues. This pistol is a little overpassed, so having a heavier buffer and spring will help with that if you don’t want to put a Superlative Arms bleed-off gas block on.
What handguard is that? Can you buy it separately?
Ghinojosa on Dec 7, 2018
BEST ANSWER: It is a PSA custom MLOK handguard. They do not sell them separately.
What is the inside diameter of the hand guard?
jason t on Sep 23, 2018
BEST ANSWER: PSA Fluted flash can diameter is advertised as 1.2” judging by the picture there’s not much more room inside. I thought the same for tucking in a supressor, but not enough room.
Can I use a pistol length upper on a lower set up with rifle length buffer?

8.5” Pistol
I absolutely love the build except for one thing. When I fire the weapon the hand guard separates from the upper. I had to modify the surface where the hand guard meet the upper in order to keep it in place.

Nice upper
This is my first pistol upper that i paired with a PSA lower SB Tactical brace.I originally wanted a 10.5 and i would not go any shorter.The upper looks and runs great although i did have to tighten the M-Lok rail.

Can’t beat the quality or price.
Great fit and finish, was a little tough to get the magpul sights on though. Not sure how other slip on attachments will work.
