Element M125 VSR-10 Spring

The Element M125 VSR-10 Spring is only suitable and therefore especially designed for the VSR-10 Airsoft Sniper rifles.

We regularly receive questions about which spring gives which fps / joule, which is very difficult to estimate because it depends not only on the spring, but also on the air seal of the cylinder, piston and piston head. The air seal of the cylinder, piston and piston head also have a large share in this.
