Madbull Gear & Piston Lubricant Maintenance Set

The Madbull Airsoft Grease Set features two 5ml containers: a transparent silicone lube for your piston/O-rings, and a dark grease for your metal gears.

Together, they maximize your air seal, reduce friction, and prevent wear and tear inside your AEG gearbox.

To get the most out of your Madbull piston and gear grease, it's all about correct application:

Piston / Cylinder Grease (Clear/White): Use a tiny amount of the silicone-based grease on your piston head O-ring and lightly coat the inside of the cylinder. It seals the cylinder for better FPS consistency without swelling or destroying the rubber O-ring.

Gear Grease (Black): Apply a thin layer strictly to the teeth of your gears and the bearing/bushing tracks. This high-viscosity grease stays in place without flinging off during high-speed rotation.

Warning: Avoid using too much grease! Excess grease can migrate into the barrel and ruin your hop-up, causing inconsistent or dropping BB trajectories.
