Lonex AEG spring - M120

High-quality progressive tuning spring for electric airsoft guns manufactured by Lonex. Irregular wire density reduces the effects of compression and extends the life of the spring. This M120-level tuning spring provides approximately 120 m/s (1.44 J) of power with a 0.20g bullet. The final muzzle velocity of the bullet and the power of the weapon depends on the weapon, bullet weight, barrel and the rest of the mechanism.
