The BOLT M is an HPA conversion kit for bolt-action sniper rifles. It helps you stay concealed, focused on your target, and conserve air. Since it is inherently quiet, you can be the truly stealthy sniper. With no spring involved, you can cycle the action smoothly while staying locked onto your target. With our Air Saver technology, you get the most out of your HPA tank or CO2 cartridge. Requiring no FCU or battery, the BOLT M delivers pure, reliable mechanical performance.
Features
- Simply perfect performance: Based on the legacy of the original BOLT system, the BOLT M delivers top-tier performance.
- Fully mechanical: The completely mechanical design provides more convenient and reliable battery-free operation.
- Stay on target: The smooth, spring-free action makes it easier to keep your sight on target, improving follow-up shot speed and accuracy.
- Easy installation: Quickly switch between spring and HPA thanks to an innovative air connection system.
