AEG nozzles

The Nozzle is the last component connected to the gearbox and ensures that the accumulated air pressure (caused by the spring, piston and piston head, cylinder and cylinder head) is blown against the BB and the BB gets fired.

Nozzles to upgrade your airsoft gun usually provide a better air seal because they have a double o-rings inside the nozzle and make contact with the cylinderhead. There are Polycarbonate Nozzles which are light and strong and there are aluminium nozzles which last a lot longer than the Polycarbonate Nozzles but are slightly heavier.
