Ultimate bearing metal spring guide Ver 2

ASG spring guide with bearing. Its tough metal construction makes it suitable for even the strongest springs. This spring guide has a unique rotating body with the spring leaning on it, which makes its rotation easier and reduces resistance leading to a smoother gun operation.

Works well with a piston head with bearings. The spring is then set freely with smooth axial rotation, which reduces the resistance during its compression to a minimum.

Suitable for guns with V2 gearbox (M4/16, G3, MP5, etc.).
