a note on screwdrivers. Get good ones, and I don't mean just name brand, I mean GUNSMITH screwdrivers. The flats are ground parallel. not tapered like most screwdrivers. your screw slots are straight sided meaning most screwdrivers only contact at the very top edge.

that is the first set I came across, they are pretty spendy but they don't damage stuff.
