Howdy, Picasso here!
Back again just looking for some tech answers. Currently I'm making an M4 dream rifle build. The rifle is NOT EBB and is a plain-jane aeg. I'm going all out on the luxuries and making sure I have all the bells and whistles.
Right now im worried about a good dust cover plate and bolt catch. Since, I'm starting from stratch, I have NO specific parts that come with the receiver I will order.
Any recommendations on a dummy bolt that you can "catch" with, with the little button doohickey on the side of the receiver?
