scorch Posted June 1, 2010 Report Share Posted June 1, 2010 My girlfriend's M190 isn't working on full auto. Does anyone have any idea what causes this or have any pics or diagrams for it? There maybe something worn, or something missing even. Her ex thought a bunch of PTFE tape was a decent substitute for an o-ring in the bullet-valve, so god only knows whats been done to the poor thing. Thanks in advance.
