Quantum Trigger – Ultra-Fast Response

The included CNC-machined Quantum Trigger provides extreme control with:

• “Hair-trigger” sensitivity – up to 60 settings within the first millimeter
• Instant trigger response for competitive gameplay
• Precise tuning for CQB, speedsoft, and tactical scenarios

Advanced Performance & Technology

• Full brushless motor compatibility (optimized for 11.1V setups)
• Reduced heat generation under heavy load
• Spring support up to M200
• Improved sensor diagnostics for reliability
• De-cocking function (Rev.2)

This ensures consistent and reliable performance even in demanding builds.
