ULTIMATE M170 Spring
- 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.
