Modify Coil Spring Guide has coiled design of the bearing core to enhance efficiency of rebound during spring release to minimize deformation of spring due to firing, improving its durability. Its special single-piece base is extra durable.
Its spring guide to stop pushing of bearing reduces deformation of spring during compression minimizes load on motor, also extending life of the spring and preventing damage to .
- Of steel construction, it is designed to minimize load on the caused by torsion. One-piece base and 2 wings for improved durability.
- The Rotary Shaft design improves spring return effectively.
- It fits any spring from stock to M170.
