- Made of T6061 aluminum for lightweight and durable use
- Realistic appearance with various gun manufacturer's markings
- A lighter bolt than normal provides smooth action and sharp recoil.
- Less affected by low temperatures, allowing you to enjoy GBB for longer periods throughout the year
- Steel stays have been installed on the contact surface to prevent the bolt stop from failing to engage, which was a common problem with genuine bolts due to wear over time.
