Externally is excellent condition, like-new. Comes with 5 functional shells. Purchased a couple months back brand new. Left it to sit, then like typical JAG Arms quality, is now leaking.  Never even fielded it.  Attempted to disassemble and fix it, but gave up as I've already got too many other projects to work on.  Might be an easy fix if you've got some time on your hands. My guess is that you'd need to lube up some orings since it's been sitting around for whole winter. Again, idk since I didn't completely disassemble it. Lost the spring for the mock ejection cover in the process .  Doesn't affect functionality whatsoever, can still toggle between 3 and 6 round bursts. * $155 shipped and fee'd!
