AIRTECH STUDIOS BEU BATTERY EXTENSION UNIT VFC AVALON PDW

The BEU (Battery Extension Unit) from Airtech Studios is an upgrade accessory specifically designed for VFC Avalon PDW series airsoft rifles.

It expands the internal battery compartment of the PDW stock, allowing the use of larger and higher-capacity batteries without altering the rifle’s external profile.

By increasing available space, the BEU helps reduce stress on internal components such as wiring, MOSFETs, and fuses, minimizing the risk of bending or damage caused by cramped battery placement.

Ventilation slots on both sides help maintain airflow around the battery and electronics, which can reduce heat buildup during extended play.

Once installed, the stock remains compact and functional, retaining full compatibility with original PDW ergonomics.

This extension unit is constructed from durable polymer that resists impact and rough handling, and fits seamlessly inside the stock without permanent modifications.

Key Features:

- Expands internal battery compartment for larger batteries

- Reduces strain on wiring and electrical components

- Improves ventilation around battery and electronics

- Durable polymer construction

- Designed for VFC Avalon PDW series stock systems
