AEG M150 Spring for Airsoft Replicas - Compatible with SVD

The spring is one of the most important internal components of an airsoft replica, directly affecting power, muzzle velocity, and shooting range.

This M150 spring with variable winding is made from heat-treated SiCr alloy steel wire, a material specially designed for springs exposed to repeated stress and intensive use. Its high-quality construction ensures excellent durability and consistent long-term performance.

The spring has been tested under real airsoft conditions and endured over 10,000 shots without any loss of power or change in length.

Thanks to its variable (non-linear) winding design, the initial compression requires less force, resulting in smoother cocking while maintaining the same final spring power.

Compatible with most AEG gearboxes and suitable for SVD sniper rifle replicas as well as Guarder pistons.
