now that you mention it, I just put mine together a couple months ago. And did'nt notice one.

Not a stupid question... yes they do have them, and no I dont think I've ever used one either... no worries.

yeah there should be an o-ring that goes around the sleeve. many time it gets stuck between the cylinder and sleeve and you do not even notice it really. It should be there, but i have never replaced mine
