DeepFire bearing metal spring guide Ver 2

DeepFire steel spring guide with bearing. Its tough metal construction makes it suitable for even the strongest springs. The ball bearing makes the rotation of the spring 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.).
