Why Upgrade Your Pistelle X-68?
The tuning chamber and rear adapter system gives you considerably more flexibility when configuring your Pistelle X-68.
The tuning chamber increases the available air volume within the system, while the rear adapter creates an interface for compatible buttstocks, air-system components and other rear-mounted accessories.
This makes it possible to configure the Pistelle X-68 for improved stability, handling and ergonomics.
If you are building the system from the ground up, start with the Pistelle Max Power Tuning Chamber. This forms the foundation of the modular system and is designed to work directly with this rail buttstock adapter.
Actual launcher output will vary according to the complete setup, air source, projectile, operating pressure, temperature, seals and overall condition of the launcher.
Compact or Standard?
Compact
The Compact version is the better choice when you want to keep the Pistelle X-68 setup as short and streamlined as possible.
It is well suited to configurations where reduced overall length and a compact rear profile are important.
Standard
The Standard version provides a more conventional extended rear configuration.
It is better suited to users who want additional space for their chosen buttstock or rear air-system setup.
Both versions are designed around the Pistelle X-68 platform.
Compatible Pistelle X-68 Products
One of the main benefits of this adapter is that it forms part of a larger modular Pistelle X-68 system.
Pistelle Max Power Tuning Chamber
The Pistelle Max Power Tuning Chamber forms the foundation of the upgrade system.
The rail buttstock adapter attaches to the tuning chamber and provides the interface needed for additional rear-mounted components.
MCS Folding Air Buttstock Adapter With Gen3 Locking Mechanism
For a folding rear configuration, pair the system with the MCS Folding Air Buttstock Adapter With Gen3 Locking Mechanism.
Its down-folding design lowers the stock or air tank by approximately one inch from the bore axis. This can provide improved sight alignment while also allowing the rear assembly to fold for a more compact profile during storage or transport.
Pistelle X-68 Buttstock Integrated On/Off Slide Valve Adapter
For an HPA-based rear air system, consider the Pistelle X-68 Buttstock Integrated On/Off Slide Valve Adapter.
This adapter features an integrated on/off slide valve and controlled air-bleed function. It is specifically designed for buttstock-mounted HPA configurations and is not intended for CO₂ use.
Air Valve ASA Air Tank Chamber Compact Plug Adapter
If you are not using an external air tank or ASA accessory, the Air Valve ASA Air Tank Chamber Compact Plug Adapter can be used to close the unused ASA port.
Its low-profile design helps keep dirt, dust and debris out of the air-system connection while maintaining a neat, compact setup.
Defense Innovation Pistelle X-68 Gen2
This upgrade system is designed for use with the Defense Innovation Pistelle X-68 Gen2.
The Pistelle X-68 Gen2 is a 0.68 calibre magazine-fed launcher that provides the base platform for this modular tuning chamber and rear accessory system.

Care and Maintenance
Before installing, removing or adjusting any part of the tuning chamber or buttstock system, ensure that the launcher is completely unloaded and the air system is fully depressurised.
Regularly inspect:
- Threads and mounting surfaces
- Retaining screws and mounting hardware
- Seals and O-rings
- Air-system connections
- Rear rail interface
- Buttstock or ASA adapter connections
Keep all threads and mating surfaces clean and free from dirt, grit and projectile residue.
Never force threaded components together. If a part does not turn freely, remove it and inspect the threads before continuing.
Only use lubricants that are compatible with the Pistelle X-68 air system and its seals.
For ongoing maintenance of your launcher, the Pistelle X-68 Gen 2 Upgrade Seal Kit and Lubricant Grease is also a useful addition to your setup.
