Mercury Rise IntruBuster Gen2 Extreme Performance Tuning Chamber + Tuning Buffer Buttstock Kit (Estimated Shipping 10/09/2026)

Extreme Performance 100+ Joules Tuning Chamber – Mil-Spec Buffer Tube, engineered to increase available air volume and support maximum performance without requiring internal modification. The tuning chamber attaches directly to the marker and increases the system’s air volume to help deliver greater power potential. The original 12g CO₂ cartridge in the pistol grip continues to operate as normal, allowing you to retain the standard air system while adding the benefits of an external high-volume tuning chamber. No internal modification is required. The system is designed for a straightforward installation, making it an easy performance upgrade for compatible MCS platforms. Machined from 6061 aircraft-grade aluminum, the tuning chamber provides excellent strength, durability, and corrosion resistance while maintaining a lightweight profile. The integrated Mil-Spec buffer tube is compatible with standard Mil-Spec buttstocks, giving you the flexibility to customize the marker with the stock configuration of your choice.
