As the only sc marker I have is my phantom, I carry all kids of different options for it.
I carry 2 sight rails, a ghost ring, an offset sight rail, a cp rail and ccm on/off, 7" of macro, a bba, rf body(just in case) a drop out changer, a complete set of internals, bottle of oil, and a lapco sc/oc adapter. As for my tool kit: set of detent rings, 3 new feedgates, all kinds of screws orings and seals, 2 spring kits, and an assortment of allen keys.
