Includes one green gas magazine, no leaks It is missing the RMR mount on top of the slide, which also houses the nozzle return spring. The spring is missing too. It does seem to work fine as it is, but I assume issues will eventually arise if you use it without the nozzle return spring... for this reason consider it boneyard. The magazine is missing a base plate but works properly. Slide catch on empty works. I will offer a shooting video on this one but please only serious inquiries.
