Does the handguard have a QD mount ?
Paul I on Jan 3, 2019
BEST ANSWER: Yes! One on each side
Will this upper work with my carbine style lower?
Don on Oct 26, 2018
BEST ANSWER: As long as it is Mil-Spec. BUT, this is a PISTOL upper. You need to put it on a PISTOL lower. To put it on your carbine lower, would make it an SBR, because the barrel is sub 16". That is a felony.
Does this mean the upper is fully automatic or semi automatic?do I have to go through and FFL to purchase this?
Chris e on Mar 12, 2019
BEST ANSWER: No FFL is required.......I'm assuming your question is related to the "full auto bolt carrier", and no, this does not make this an automatic rifle, but then automatic, or semi has little to do with the upper receiver
Is it legal to build an ar 15 pistol in California?
Edward F on Jan 3, 2019
BEST ANSWER: Since YOUR choices affect that … YOUR Buffer Tube + 17" = OAL
What is the overall length of this upper?
cvjagman748 on Jan 3, 2019

Total length fully completed with buffer tube and lower assembly?

Upper/receiver seem to be out of spec
Just got my upper from PSA today. I built it on top of an Anderson lower and it wouldn't seat in unless I put some heavy pressure to lock it in. I'm not sure if it's the upper or the lower receiver thats not milled to spec but it seems like the upper ori lower receiver seems to be canted a bit. I have yet to fire some rounds through it. Until then the pistol assembly and the kit looks great.

Beware the recoil
I can't say enough how awesome PSA products are. I now use them almost exclusively. This kit was no different. Having built a 300 BO pistol I now wanted a 556 pistol. As I did not intend to use a silencer on this build I decided to go with the smallest pistol barrel length I could. Using a cheap NC Star optic I was able to accurately put rounds down range at 100 yards, the average group was probably around 4 inches or so. Not bad for this shorty but beware the recoil and blast! Yeah, with this short of a barrel you'll get significantly more felt recoil, although not unmanageable, as well as some back blast from the shorter barrel. In fact, I was getting hit in the face with some unburnt powder. Nothing unusual or hard to handle, but unexpected on the first few rounds.

Fun, buy one.
Runs great! Lots of fun. I always wear plugs and muffs anyways, so the sort barrel doesn't bother me. Never bothered to test it for accuracy at 100 yards so I can't give it 5 stars.
