Battery compartment

[SemiLethal]

How does the forgrip/battery compartment attach? Are any other parts contained in it?

[<IONFREAK>]

It slides onto a rail on the front of the trigger gaurd and is secured by a set screw.

The board is aslo in the foregrip. (not including the board for the eyes). The board for the eyes and HES trigger activation point is directly connected to the board in the foregrip using a plug going from one to the other.
