The BEU™ is designed by Airtech Studios to fit beautifully with the ICS PDW's original design by sitting seamlessly inside the stock compartment offering two points of shoulder adjustments to ensure compactness and maneuverability.

Made of strong, flexible nylon that is resistant to BB impact and rough handling. With the extra air space inside the compartment, the BEU™ 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.
