CO2 cartridge holder for CTR type stock (ATD)

This part is a compact storage module specifically designed to be mounted on an M4 CTR-style stock. Its purpose is to allow the carrying of a 12g CO₂ cartridge. It is practical and immediately accessible when using CO₂-powered HPA systems.

The module integrates directly into the stock's geometry without hindering the replica's ergonomics or shouldering, while adding a convenient feature for users of HPA systems such as the Wolverine Wraith or PolarStar CGS kits.

The CO₂ cartridge is held securely in a dedicated compartment that prevents any movement or unwanted noise during transport. The retention system also allows for quick access: the user can remove the cartridge in seconds, facilitating replacement or refueling of a compatible CO₂ HPA system in the field.

Screws are included with the mount. Stock not included.
