Gear-box components

This item made by aluminum body, so it can be protected from crack caused by screw biting. Body has been treated by alumite, so the surface of bullet feeding route is smoother. O-ring is used and it absorbs the impact at magazine inserting and makes the adhesion for opening of this item and ..

Helical red polycarbonate piston with fifteen teeth. The first five teeth are of plastic, the remaining ten are metallic. We recommend using this piston with model Helical gears for upgrades of up to 190 m / s...

Red polycarbonate piston with 15 teeth. The first five teeth are plastic, the remaining ten are metallic. We recommend using this piston for upgrades to 170 m / s..

The polycarbonate piston head (16608) or the aluminium piston head (16609) have built-in pressure bearings to reduce friction from the spring. The piston head are ventilated making sure that the rubber seals are pressed against the cylinder sides when the air is compressed. This gives optimal compre..
