Does this ship to California?
Robert G on Dec 7, 2018
BEST ANSWER: It will ship, this upper is completely legal in all the other non communist states. It's up to the comrade to please the state.
Where does the third spring and detent go that came with the takedown pins?
DurtayMcGurtay on Dec 15, 2018
BEST ANSWER: The third spring and detent goes in the lower... because the FIRST one has usually gone sailing across the room.
What lower do you recommend?
Darren T on Dec 6, 2018
BEST ANSWER: Personally, I overwhelmingly prefer the Aero Precision M4E1 forged lowers for these PSA build kits, but the PSA lowers are excellent fits for these kits as well. As all the rest have previously stated in this thread, ANY mil-spec lower will do just fine, including the well-made, inexpensive Anderson lowers. Still, the Aero Precision for me are the best-built, best engineered for the price. Good luck with your build!

Dk44689 on Apr 7, 2019

Dk44689 on Apr 6, 2019

Dustin B on Jun 17, 2019

Does the MBUS front flip-up work with this handguard or does it need modification like it does with Aero handguards?
Mark S on Apr 28, 2019
BEST ANSWER: I don't use the Magpul sight specifically, but I have an el cheapo knock off for the time being and it fits fine. Granted I had to slide it on rather than pop it on because the sight doesn't stretch any after loosening it up, but it has not given me any problems. Assuming the MBUS is as close to the knock off as it should be, it should fit just fine.
Wen will this deal end?
Jeff L on Dec 13, 2018
BEST ANSWER: When PSA decides to end it.
What kind of ammo do it shoot?
L H on Jul 1, 2019
