This is a super old Tokyo Marui G3a3 in great external condition. Internally I modified a Krytac complete gearbox to fit this replica. When I opened the gearbox I installed a tm selector plate, tm air nozzle, shs pre lightened metal rack piston and a guarder sp100 spring. This is a sweet battle rifle, and is an excellent performer. I’m open to all trades offers, and I’m willing to sell. Don’t hesitate to message me with offers.
