Built with the same carbon fiber wrap and 4500psi rating as the rest of the Alpha Air line, it's designed for players who want more shots between fills without adding much size or weight.\u003c\/p\u003e\n\u003cp\u003eAt 9in long and weighing in at 1lb 12oz (0.9kg), the 77ci is only a few ounces heavier and less than an inch longer than the 68ci, while keeping the same 4.4in diameter — so it delivers noticeably more air capacity without changing how the tank fits in your hand or your tank cover.
