Stop using those "fact thingies" and personal experience to counter Internet lore.I never had any issues with my SOTA X39 upper on a DPMS lower; used ASC mags and the upgraded firing pin. Never one FTF/FTE, all using the crappies steel case ammo.
Yes, ASC mags are a little more expensive (and do look odd), but not too bad. I'm actually thinking about doing another X39 AR, but may try PSA this time since they are running a special.
