Max I’ve had, on propane firing slowly indoors is 190 shots. It will happily mag dump twice, which no other gbbr I have used has managed, including 3 GHK’s. For me, it’s not only the best GBBR but the best airsoft gun currently made.. I do love my mp7 though.
I run 5 mags and a speedloader. I’m going half of the day before I’m thinking about gas. If I was playing a milsim or somewhere there was a huge walk to the safe zone, I’d consider those little nuprol cans.
