The smart first upgrade for your VSR-10

The Action Army M120 spring is one of the most popular upgrades for the Tokyo Marui VSR-10 and its many clones, and for good reason. It gives a meaningful lift in range and power over stock while keeping many builds inside common UK site sniper limits, making it an ideal starting point for a skirmish sniper rifle.

Consistent shot after shot

Wound from quality steel in Taiwan, the M120 delivers even, repeatable pressure, which is exactly what a bolt-action rifle needs for tight groups at distance. You get more reach without the temperamental behaviour of a poorly made spring.

Where the M120 sits

As a rough guide the M120 lands around 360 to 450 FPS, though your real figure depends on air seal, inner barrel length, piston and BB weight. Always chrono your rifle after fitting and confirm it meets your site’s FPS or joule limit and minimum engagement distance.

Kind to your internals

Because it is more moderate than an M150 or M170, the M120 is easier on the piston and cylinder, so it is a great choice for a reliable, everyday sniper build. Need it fitted? Try our airsoft repair and upgrade service in Kent, or browse more upgrade parts.
