[33] 4 steps to make (almost) any blowback 9mm AR run 100% (AR9/AR-9 simple blowback)

NOT for CMMG Banshee! After a great deal of research, study and testing, I discovered (and confirmed many times over) that there are 4 simple key steps that should get almost any 9mm AR feeding, cycling, running, and ejecting properly. Note when I say "100%", I mean it should feed, fire, and function as reliably as would be expected from a typical quality firearm. No mechanical system runs 100% perfectly 100% of the time.
