High quality spring from ULTIMATE. These are double progressive springs which make sure the torque of the motor is used to its full extent, giving a higher rate of fire. This spring is chromium plated which minimises the friction of the spring on the piston. It also has an attractive white nickel finish. Chromium plating also does not wear or chip leaving debris in the gearbox like paint-treated springs. M170 produces approx 550fps, suitable for use in UK/European games. Installing this spring in the Republic of Ireland renders your AEG an illegally held firearm. View our entire range of ULTIMATE parts here .
