SHS M4 LEVER SPRING (PPS-12026)

SHS M4 winding arm spring. To adjust the hop-up of M4 replicas, the cocking lever must be pulled back, this spring helps to pull the cocking lever back to its original position. If we adjust the hop-up many times, this spring may tire over time. Another problem that occurs is if the winding lever is overstretched, thus stretching the spring.

We can only guarantee the parts we install!
