I'm thinking that I'd like to buy an Eotech for use on both my 870 and M1A.
I know the new super-moneybags-deluxe model has throw levers integrated which would lead me to believe it is intended to repeat zero. But what about the 510 model? Does a special mount need to be obtained (like the GG&G accucam)?
Most importantly, Is the Eotech designed in a way where I could mark off and switch settings based on the weapon it's attached to?
