Now we are talking

The Rebel M100 is our best-selling power spring, and for good reason. At approximately 330fps it delivers a strong, confident output that suits a wide variety of AEG builds, giving you noticeably more range and reach while staying dependable shot after shot.

Room to build

One of the M100’s strengths is the headroom it offers. If you are pairing your spring change with a tight-bore barrel, remember that a tighter bore can itself lift your FPS. The M100 gives you a little wiggle room to account for that, so your finished build lands where you want it rather than falling short.

A guide, not a guarantee

The 330fps figure is approximate, based on an average AEG setup. Your real output depends on barrel length, air seal, compression and hop, so always chronograph after fitting and test against your site’s limit, since around 330fps sits near the top of many UK AEG limits.

Fit it right

Fitting a spring means fully dismantling a gearbox under tension, so we recommend an experienced technician for the job. Our Tech-It repair service in Kent can handle it. Explore more upgrade parts in our airsoft accessories range.

Frequently asked questions

What FPS will the M100 give?

Around 330fps on a 0.20g BB as a guide. The exact figure varies with your barrel, air seal, compression and hop setup, so chronograph after fitting to be sure.

Why is the M100 so popular?

It hits a sweet spot of range and reliability that suits a huge variety of AEG builds, which is why it is our best-selling power spring. It gives good performance without pushing power to extremes.

Is it a good match for a tight-bore barrel?

Yes. The M100 allows a little wiggle room if you are installing a tight-bore barrel, which can itself raise your FPS. That headroom helps you land on your target output.

Will it stay within site limits?

Around 330fps is near the upper end of many UK AEG limits, so check your site's specific rules and always test on their chrono before play.

Should I fit it myself?

Spring changes require fully stripping a gearbox under high tension. We strongly recommend an experienced technician, as incorrect fitting can cause damage or failure not covered by warranty. Our Tech-It service can fit it for you.
