Product Description
This is for those who has a next-gen Tokyo Marui 416 or SOPMOD, and have done the battery mod, this pad allows you to hide batteries in the stock pad instead of having to use a SOPMOD / Vltor style stock. Fits Magpul MOE style stock, recommend using a velcro strap that goes between the sling slot in the back of the stock to secure the lower half of the stock as it's no longer affixed by a pair of screws like the original.
I have only tested this with my owner printer, and holds a pair of 7.4v nunchuck style 1400 mah lipo battery in the compartment.
