Element VSR10 M145 ST Spring

Tuning spring for the VSR-10 spring-piston system

The Element VSR10 M145 ST Spring is a tuning spring made from hardened spring-steel wire for the spring-piston system of a VSR-10 sniper platform. Its irregular winding gives a more even spring travel inside the cylinder and replaces the factory spring in that position.

What the designation means and compatibility

The M145 designation describes the spring's relative strength within the Element line-up and is meant for comparing the steps of the series; it does not translate into a fixed muzzle velocity, which also depends on the cylinder head, piston and barrel of the individual build. The spring is intended for installation in VSR-10 systems and compatible platforms and is supplied as a single replacement part.
