Valken M17 A2 Black High Joule Set: Extreme Power and Consistency (50 J – 70 J)

This set is intended for demanding users who want to extract the absolute maximum performance and reliability from the Valken M17 A2 Black platform. By installing the ASA Tuning High Joule kit, the M17 A2 is transformed into a highly consistent and powerful marker, ideal for use with heavy rubber or polymer projectiles and for tactical training.

Key Advantages and Expertise 

Extreme LL Power: When using an HPA tank with a high output pressure of 1100 PSI (High Pressure Output), the set is capable of achieving kinetic energy in the range of 50 J to 70 J. This configuration is necessary to achieve peak performance and is intended for specific use.

• Consistency Core (HEAT CORE): The main component is the ASA Tuning HEAT CORE Chamber. This is an enlarged valve chamber that ensures maximum air volume per shot and minimal pressure drop between rapid shots. This is crucial for accuracy and reliability in LL (Less Lethal) systems.
• Optimized Mechanics: The set includes a complete set of tuning springs optimized for 1100 PSI pressure, ensuring the marker cycles correctly even at high power settings.
