Prometheus Airsoft Hard Piston 15 Tooth 7 Steel Tooth G&G Series AEG Upgrade

Prometheus Hard Piston for G&G Series – 15 Tooth

If you’re upgrading a G&G AEG and want something that’ll actually survive a high-stress build, the Prometheus Hard Piston 15 Tooth from Bullseye Country Sport is a serious bit of kit. Designed by Laylax / Prometheus in Japan, this upgraded piston is built specifically for players running stronger springs, high-speed setups or heavily customised gearboxes where standard pistons just don’t last.

The piston is one of the most important parts inside your gearbox, acting as the connection point between the gear train and the compression system. Because of that, it takes a serious hammering during every cycle — especially in rifles running upgraded motors, faster gears or higher FPS builds.

To improve durability without adding unnecessary weight, Prometheus designed this piston using reinforced lightweight materials with excellent resistance to:

friction

wear

impact stress

heat buildup

The 15 tooth design provides strong engagement with the sector gear, while the lightweight construction helps reduce stress on the gearbox during high cycle builds. It’s particularly well suited to upgraded G&G platforms and custom AEG setups where reliability matters just as much as performance.

Finished in black with Prometheus’ usual clean Japanese manufacturing quality, this is one of those internal upgrades that serious techs trust for long-term durability.

At Bullseye Country Sport, we reckon a quality piston is one of the smartest upgrades you can fit if you want a custom build that actually lasts more than a few game days.
