So is the bolt catch just for looks?
Damain A on May 25, 2018
BEST ANSWER: I use a spartan upper from Joe Bob Outfitters that has a LRBHO and bolt holds open fine
Will this work with the PSA uppers that are not hybrid uppers? Also, will uppers from other companies work
Tyler C on Jun 10, 2018
BEST ANSWER: Yes this will work with any mil spec upper
Is this a pistol lower? Or rifle
Zebulan D on Jun 6, 2018
BEST ANSWER: I used it for a PCC but it does have a set screw in the back that captures the detent spring. Don’t see any reason it can’t be used for a pistol build.
My glock factory magazine is not seating fully so most rounds are jamming back into the casing. Is there anything i can do to fix this?
DeAndre G on Jul 8, 2018
BEST ANSWER: I have two of these lowers and think the problem is you should download your magazines, and open your bolt before you insert the first mag. If these a your loads check your cartridge's overall length
. Could be too long.l
Does this really only work with their hybrid upper? And does anyone know if you can just purchase the upper receiver rather then the complete upper?

PSA PA-X9 Lower
Extremely impressed with my PA-X9 build using this stripped receiver. Accepted my mil-spec parts with no issues. I am running a 5.4oz buffer and have had zero feeding or cycling issues using factory glock mags (have not tried aftermarket).

PSA 9MM lower
I tried to put the PSA upper on my Lower and the bolt drags heavily on the extractor. It did not fit properly and I don't feel it will cycle properly. The bolt will hardly move so not happy.It does look good.

Great 9mm lower!
I bought this dedicated 9mm lower because I was experiencing hiccups with a drop in 9mm kit I picked up, wow!! I wish I’d just gone ahead and got this thing 6 months earlier! I bought a 16” and 10.5 9mm PSA uppers and they run Flawlessly after pumping over 1200 rounds through the pair of them and this lower, save yourself money and headaches and grab one of these lowers!! You won’t regret it at least I don’t!

PSA Billet Upper Works Great
Works great. If you want bolt hold open on the last round you will have to get an upper with lrbho. This lower works great with this upper...New Frontier Pistol Caliber Billet Upper. I have shot hundreds of factory and handloads with this lower without a hiccup. I like the Glock mags setup. The mags are very reliable and are cheap. PSAhas fast shipping sometimes, other times not.
