2 FDV v3 510's with the 22mm washer, OKR T10 chip, potentiometer, firing button, dual 18650 battery sled, 20 gauge wire, heat shrink, neodymium magnets and I think that is it. All the rest of the stuff for me to build an OKR box mod arrived today. The 510s are due on Friday, but the other stuff is due tomorrow. Maybe I will spend Thursday soldering before I have to go see people.
