A measured power upgrade

The Rocket (SHS) M110 spring is a popular way to lift your airsoft AEG’s output to a moderate skirmish level. As a rough guide an M110 sits around 350 to 400 FPS on a 0.20g BB, though your real figure depends on the rest of your setup.

Smoother by design

Rather than a plain straight-wound coil, this spring uses an irregular, non-linear pitch. That lets it compress more smoothly, which eases the load on your motor and gears and helps deliver a more consistent shot. It is a small detail that makes a real difference to feel and longevity.

Built for reliability

Wound from high-grade steel, it holds its rate well over time so your FPS stays where you set it. It fits standard V2, V3, V4, V6 and V7 gearboxes, covering almost every electric replica on the market.

Fit and check

A spring change is one of the more accessible internal upgrades, but always chronograph afterwards and confirm you are within your site’s limits before you play. Grab a shim set and other internals from our airsoft accessories, or book in with our Kent repair and servicing team.

Frequently asked questions

What FPS will an M110 give me?

As a guide, an M110 typically produces somewhere around 350 to 400 FPS on a 0.20g BB, but the exact figure depends heavily on your air seal, compression, barrel length and cylinder setup. Always chronograph after fitting.

Why an irregular-pitch spring?

The non-linear pitch compresses more smoothly than a straight-wound spring. That can reduce stress on the motor and gears and help with consistency, which is why many techs prefer this style.

Which gearboxes does it fit?

It suits standard AEG gearboxes including V2, V3, V4, V6 and V7, covering the vast majority of electric replicas.

Will this keep me site-legal?

That depends on your complete setup and your site's limits. Always chronograph your gun after any spring change and check it against your local site rules before playing.

Do I need to change anything else?

A spring swap is straightforward, but it is a good moment to check your piston, cylinder head and air seal so the new spring can perform. Our Kent servicing team can fit and chrono it for you.
