hey. i just got my hands on an em1. i know some things between them are compatible, and that operation is simular. I know the vert adapters for ca are compatible, are the lpr adapters compatible also? also, how different are the bolts? and what about electronics, can i get bushmaster boards and use them in an em1? lmk about all around compatibility too, not just the things i asked about, teach me fellas.
