Description
M120 main spring
The main spring is intended for tuning electric replicas (AEGs) and 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 ~380-390 FPS. However, it should be noted that the final muzzle velocity achieved by mounting 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.
