G&G ARP9 Black and Gold with Perun MOSFET upgrade installed. Only ever used twice before I stopped playing and has mostly been a wall piece so it's in excellent condition. Comes with the battery, the card to program the upgraded MOSFET, original hi-cap stick magazine, a 1500 round winding hi-cap drum magazine, and a Red/Green Red Dot Sight with 4 different reticles complete with a sight protector.
