This is a PSA 9mm Hybrid designed to take Glock mags. I just re-checked the PSA site and it states "Accepts standard AR-15 fire control groups, bolt catch, take down & pivot pins, springs & detents, safety selector as well as stock, buffer tube and grips." I replaced the triggers in my Colt 6920s with Geissele SSA triggers and used one of the factory Colt triggers for this build but that shouldn't be an issue.

Originally, I thought I messed something up with the buffer (factory KAK pistol blade kit) but it could very well be something with the trigger. Once I pull the charge handle back, I can charge it over and over normally but once I fire a shot, it binds and is very tough to charge.


Better check the specs on that upper.

Some of the PSA 9mm uppers are only designed to work with lowers by the same manufacturer.

You didn't use logic or reason to get into this opinion, I cannot use logic or reason to get you out of it.
