GaugeMates and Chambermates are two very different versions of the same concept. Chambermates, which were available through Seminole Gunworks and is otensibly out of business due to divorce proceedings of the owner, have an ejector that functions with the host gun to eject empties, though they will only eject AA's or STS's and not any imported shell, which limits them quite a bit to those two brands. I've used my 12/20 Chambermates a lot in SC competition for 20 ga. events and they work great.

Gaugemates are just a stainless steel sleeve that has no moving parts, so you have to remove the entire unit each time to remove the fired hull, UNLESS you do a simple procedure of grinding away a small part of its rim to allow room for your fingernail to engage the rim of the fired hull and remove it and leave the GaugeMate in the chamber. It works just fine to do this, but there is a major drawback in that it is not well-suited to ejector guns.
