THE DRUM MAG WILL NOT BE SOLD SEPARATE. This is a kwa mp7 with a tapp Airsoft electric winding drum mag. The drum mag is brand new and only used in game for 1 event and ran without a single hiccup. This has the stock bolt in it so I could get higher fps. It will come with the upgraded rail segment and the flash hider that will take screw on style suppressors. Drum mag holds 1500 rounds. Only trade I will do is for a working polarstar jack or f2. THE DRUM MAG WILL NOT BE SOLD SEPARATE. Buyer pays shipping
