Kublai K1 M4 Gel Blaster Assault Rifle

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!
