Effortless Installation! By offering additional spacing inside the compartment, the Battery Extension Unit (TBEU™) is designed specifically to relieve all stresses on the KWA rifles components such as the MOSFET and to prevent the bending of electrical cables to protect it throughout, increasing its durability.

70% Greater In Battery Compartment Getting ready for your next battle can be a chore by taking a long time to charge up all your batteries. The TBEU™ will enable larger batteries to be used to ensure you remain in the battle for longer!

Same Flexibility After Installation The TBEU™ is designed to fit beautifully with the KWA PDW's original design by sitting seamlessly inside the stock compartment offering two points of shoulder adjustments to ensure compactness and maneuverability.

Compatible on all KWA PDW Stock Series The TBEU™ is highly versatile and can be used across the KWA PDW series. Once installed the added compartment eliminates the rattling butt-stock by locking-down the two metal rails!

Light & Strong Construction Made of strong, flexible nylon that is resistant to BB impact and rough handling. With the extra air space inside the compartment, the TBEU™ will protect the MOSFET, fuse, wires, and battery from overheating over time. Likewise, we wanted to minimize the prospect of denting the battery's surface from the cramped spacing.
