Turn up the power on your VSR-10

The Action Army M150 spring is a proven upgrade for the Tokyo Marui VSR-10 and the huge family of VSR-10 based clones. Swap out the stock spring for this M150 and you unlock a strong jump in muzzle velocity, extending your effective range and giving your shots more authority downrange.

Consistency you can rely on

Made from quality steel and precision-wound in Taiwan, the spring delivers even, repeatable pressure shot after shot. For a marksman rifle, that consistency is everything: it is what keeps your BBs grouping tightly at distance rather than scattering.

Where the M150 sits

As a rough guide the M150 lands around 480 to 600 FPS, though your real figure depends on air seal, inner barrel length, piston and the BB weight you run. This is a high-power spring, so always chrono your rifle after fitting and confirm it meets your site’s limit and minimum engagement distance.

Get the most from it

A stronger spring loads the internals harder, so pair it with a good piston, cylinder head and spring guide for long-term reliability. Our in-house techs can fit and tune it for you: see our airsoft repair and upgrade service in Kent, or browse more upgrade parts.

Frequently asked questions

What rifles does this spring fit?

It fits Tokyo Marui VSR-10 and the many VSR-10 based clones and platforms, which share the same spring and cylinder format.

What FPS will an M150 give me?

As a guide the M150 sits around 480 to 600 FPS, but your actual figure depends on air seal, barrel length, piston and BB weight. Always chrono before play and stay within your site limit.

Is this spring legal for my site?

An M150 produces high energy that can exceed some site sniper limits. Check your site's FPS and joule limit and minimum engagement distance before fitting, and chrono after install.

Do I need other upgrades to run it?

A stronger spring puts more load on the internals, so it is best paired with a quality piston, cylinder head and spring guide for reliability and to get the most from the extra power.

Where is it made?

It is made in Taiwan by Action Army, a well-respected name for VSR-10 and bolt-action upgrade parts.
