- Maximum performance and reliability
- Guarantees good transmission response
- Higher RPM: improves acceleration and recovery
- The bolt is made of chrome-nickel steel, which gives it a coefficient of very low friction.
- Contrast spring with 10% more hardness, thus increasing the rotation speed at the outlets.
- The large internal pocket of the bolt acts as a reservoir of grease: there is constant lubrication inside, even in the most extreme conditions of use.
