Lancer Tactical Airsoft M110 Spring Quenched Japanese Certified, Black

Need to bump your AEG's velocity or replace a worn-out spring? This is Lancer Tactical's M110 spring — a steel upgrade spring designed for players who need more power than stock, without jumping all the way to a full custom build.

What an M110 means in practice. The M-rating is a rough guide to the velocity a spring produces in an otherwise standard setup, but the actual number depends on the gun's inner barrel length, air seal quality, and cylinder head setup. Chrono before you play, always.

It's a parts play. Steel construction means it holds its rate longer than the budget cast springs that come on entry-level guns. The compatibility is broad: it fits most standard AEG platforms including M4, AK, and G36 families. If your old spring broke, lost tension, or was just too weak for the fields you play, this is a straightforward drop-in upgrade.

Before you buy. Higher spring weight draws more current from the motor and runs the battery harder. If your gun doesn't already have a MOSFET, running an M110 on 11.1V LiPO is asking for trigger contact wear. A MOSFET isn't optional on a high-current build — it protects the contacts from carrying full motor current. You'll need a battery and charger separately; they don't come with the spring. The spring itself weighs 0.7 oz and ships in a plain package with no extras beyond the spring.
