You need a Nipple Wrench
(Available at most full-service gun stores - take
the cylinder w/ you make sure of the right fit)

(But if you have a 3/16" deep socket/1/4" drive, that's best of all)

Oh, so that's what I need. Good to know. I'll see if there's one lying around somewhere. There's so much random gun stuff, that I might be able to find out. Thanks!

Sage advice,
I will add...
If the nipples are rusted/stuck/tight the socket will be much more effective if you file the end nice and flat for a good bite.
