I'm considering buying a rubber scope eye piece for my bunny gun, one of those concertina type things.
My reasons being that it could be useful for keeping out unwanted sunshine and getting the correct eye relief instantly.
A concern is that as I wear specs this could be a problem as I will not get to block light totally out and thus will be a waste of time and cash.

Anyone here wear specs and use one of these scope rubbers? Any good?
