The spring guide serves to control the compression of the spring and reduces the pressure on AEG engine. Standard guides are often made of fragile plastic, which negatively affects their durability, so players prefer to use better custom parts.   

This spring guide is made of steel on high-precision CNC machines, which guarantees high durability and long service. Unlike the plastic ones, such guide controls the spring better and protects the rest of the mechanism.   

Steel guides were chemically burnished, which protects them from corrosion. The material makes them almost impossible to break. The guides are already equipped with a axial bearer and are ready for installation.
