The BEU™ is designed to fit beautifully with the ARP9's original design by sitting seamlessly inside the stock compartment offering two points of shoulder adjustments to ensure compactness and maneuverability.
USE ON ALL ARP MODELS
The BEU™ is highly versatile and can be used across all ARP Series and CM16 Raider L.2.0E stocks. Once installed the BEU™ eliminates the rattling butt-stock by locking-down the two metal rails!
STAY ON THE MOVE
STRONG & LIGHT CONSTRUCTION
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.

MADE FOR ALL OCCASIONS
