SHS Lightweight Polymer Piston with 14 Teeth — less mass to move, for builds chasing rate of fire. Best behind a moderate spring.

A lighter piston changes how quickly the cycle turns over. Less mass means the motor spends less of its effort accelerating it, and the gearbox comes back round sooner.

That only pays off inside limits. Lightweight pistons belong on high-speed builds running moderate springs, a battery with something to give and a gear train that has been shimmed properly.

Put one behind a heavy spring and the same reduced material that made it quick becomes the weak point. It is a specialist part, chosen on purpose rather than by default.

Good to know before you buy

Rate of fire is a system rather than a single part. A light piston helps, but the motor, the battery and the trigger unit decide most of the result.

Frequently asked questions

How much faster will it make the gun?
That depends on everything else in the build. Cutting piston mass helps the cycle along but it is only one of several things setting your rate of fire.

What spring should I run with it?
Keep it moderate. The advantage falls away once the spring load is high enough to stress the lighter material.

Is it as durable as a full steel rack?
No, and it is not intended to be. You are trading service life for speed.

⚠ This is not a heavy-spring piston: the weight saving comes out of the material itself, so a stiff spring finds the limit of it far sooner than it would a full steel rack.
💡 Titan Forge Airsoft tip: If the gun is destined for DMR use, go the other way and fit a full steel rack. Speed parts and heavy springs pull in opposite directions. Browse pistons and piston heads.
