Precision Power for Tokyo Marui NGRS

The FPS Softair M100 Spring is engineered specifically for Tokyo Marui Next Generation Recoil Series gearboxes. Delivering around 100 m/s, it gives a clean, consistent power step for recoil-shock M4, 416, SCAR-L and SCAR-H builds while keeping the trademark NGRS kick intact.

Built for NGRS, Not a Compromise

NGRS gearboxes use a shorter spring than a standard AEG. This spring is 100 percent compatible with that format, so you avoid the thread wear, poor cycling and battery drain caused by forcing an oversized AEG spring into a recoil gearbox.

Italian Made Quality

FPS Softair springs are manufactured in Italy from heat-treated carbon steel wire, giving stable power output shot after shot and a long working life under sustained fire.

Get It Fitted Right

For the best results, pair the spring with upgraded bushings, a spring guide and a ball bearing piston head. Our Tech-It repair and upgrade service can fit and tune it for you. Explore more airsoft accessories and internal parts.

Frequently asked questions

Will this fit any Tokyo Marui NGRS?

Yes. It is 100 percent compatible with Tokyo Marui NGRS gearboxes, including the recoil M4, 416, SCAR-L and SCAR-H. NGRS uses a shorter spring than a standard AEG, so a normal AEG spring must not be substituted.

What power will the M100 give me?

An M100 spring typically produces around 100 m/s, roughly 330 to 350 FPS, depending on your specific gun, barrel and other upgrades. Always chronograph and check against your site limits.

Why can't I use a standard AEG spring?

NGRS gearboxes use a shorter spring. Fitting an oversized standard AEG spring can wear the stock tube threads and cause poor cycling or reduced battery efficiency.

Should I upgrade other parts too?

For best reliability, pair the spring with upgraded bushings, a good spring guide and a ball bearing piston head. Our technicians can advise and fit these for you.

Is this spring good quality?

Yes. FPS Softair springs are made in Italy from heat-treated carbon steel wire for consistent power and a long service life.
