If I wanted to run a aero upper on the PSA Px9 lower for the lrbho would I need to run the psa 9mm bolt?
Iirc the Px-9 doesnt have LRBHO.
Right but the aero uppers have it built into the upper im just making sure I can run an aero upper on the px9 lower and which bolt I should use
Im not familiar with that upper so i cant respond. AR9s can be finicky when you go changing things though.
Yep, it works. I have an EPC upper on a PSA lower and it runs just fine. It doesn’t look bad, either, although my Aero lower is a bit more refined. The EPC upper receiver is a godsend when it comes to affordable LRBHO on a 9mm. I’m using Faxon bolts in all of them, along with KVP 7.5oz buffer and .308 carbine springs (I built them from scratch). I’m assuming the PSA bolt would work but haven’t tried.

Do you have a picture of how the aero upper looks on the PSA lower
Awesome thanks that’s what I’m leaning towards already ordered a PSA lower gonna do the epc upper with Faxon barrel and bolt

Was looking to do an EPC-9 upper and a PSA lower for the LRHBO functionality, so I’ll try your setup out.
