Kublai K1 M4 Gel Blaster Assault Rifle

The Kublai M4 is here. The most robust gel blaster we have seen so far. Some of the features include a V2 Kublai style gearbox, metal trigger/fire select/mag release & charging handle, 480 long neck motor, high-quality nylon & a functional fire select.

Parts are compatible with gen 8 metal gearing and 7mm bushings. The Kublai m4 currently has limited stock - so if you are after one I would not wait around for long!
