One of the most innovative items to come out of Marui since the MAEG's themselves. This is a functional Tactical Light that contains a 7.2v 1100mah battery to run both the TM Glock 18C and M93R MAEG's. The unit attaches easily to the bottom rail (separate item on the M93R) and extends a cable up into the main battery compartment inside the gun. Comes with charger but will need a 110v two pin mains adapter (not included).
