Product Options

Air Nozzles

Airsoft Air Nozzles

Air Nozzles feed rounds into the hop up and channel air from the cylinder through the hop up unit and down the barrel. Most airsoft nozzles are a plastic or aluminum tube with a grooved rear edge to lock into place in the tappet plate. The air nozzle sits over top the front end of the cylinder head and travels back and forth on it, actuated by the tappet plate.

Cylinder Heads

Cylinder Head

The Cylinder head acts as a contact face for the piston during the firing cycle and channels the air burst generated through the air nozzle. A plastic or metal cap that seats inside of the front end of the cylinder on the rear end, with a smaller metal tube protruding from the front end for the air nozzle to seat over top of. Two circular notches on each side seat in the gearbox shell to locate the unit and hold it in place. 

Cylinder Tune-Up Kits


A brass or aluminum tube that acts as the compression body during the firing cycle. When the piston assembly pushes forward from the back it seals up and compresses the air in the cylinder, accelerating it out through the cylinder head to fire the airsoft bb.



A plastic tube with guide slots on each side, and teeth in the bottom. The piston is actuated by the sector gear, being pulled back along it’s guides to compress the drive spring. At the end of spring compression it is released to be pushed forward as the spring decompresses.

Piston Heads

Piston Head

A plastic or metal cap with an oring groove in the side and cut ports across the face and a mounting interface on the backside. The mounting interface on the back allows the piston head to be anchored to the piston. The ports across the face channel air during the firing cycle to apply pressure to the piston head oring, pushing it out and against the cylinder, improving the compression seal.
