CA metal spring guide Ver 2

Classic Army steel spring guide with a silicone pad. Its tough metal construction makes it suitable for springs M110-M150. The silicone pad helps to reduce friction during the spring compression.

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.).
