ok everyone thanks for all your comments..
I really like the third eye/tier one tac rings with the little spirit level in...
problem.. they only do them in picatinny on my walther dommie its dovetail so I will need to convert/adapt yeah?
so firstly where do I get a quality converter rail (not one of those cheapo things from fleebay)
and second will I be able to avoid cocking lever contact
thanks for any answers in advance pete
