M130 Main spring

M130 main spring

The main spring is designed to be used in tune-ups of electric replicas (AEGs), the spring is uneven, which significantly extends the life of the system by minimising the clumping effect of the spring, provided of course that the spring is mounted in an appropriate manner. It is manufactured by the well-known company G&G.

In a typical system, the spring allows the BB pellet to be fired at a muzzle velocity of approximately ~414-425 FPS. However, it should be noted that the final muzzle velocity achieved by fitting the spring depends on the tightness of the system, the type of cylinder used, the length of the barrel and its diameter. The ends of the spring have been ground, which results in better function.
