I did the undoable!!! I fixed my Maverick's cup seal after everybody told me that once they start to leak it's all over... HAH!
all it took was my leatherman, a small adjustable wrench, and a little loc-tight
the trick was to remove the brass cupseal head that hits the valve spring, remove the cupseal plastic, flip it, and loc-tight the brass back onto the thread again.... and POOF!! air'd up and all that, it works like new!!! I'm so happy!!!!!!
I just played the West Point Combat Classic with it before the fix and I was losing 1000psi every hour or so... NOT NO MORE!!!!!
