The Battery Extension Unit (BEU) is designed to fit perfectly with the G&G PDW & CQB Series original design by sitting seamlessly inside the stock compartment with no modification required to install.

The BEU is designed to cater for larger batteries to be used with the PDW15 and relieves any bending on its components while protecting them throughout to extend its durability. Ventilation is also improved from the apertures on the BEU to protect the battery and electrical components from a build-up of heat.
