Airsoft gas bottle Extension Nozzle
Brass extension of the gas bottle nozzle by Abbey. It is used to extend the nozzle, if your magazine has a filling valve too deep and the nozzle on the gas bottle does not reach it.
Primarily designed for plastic nozzles - on metal nozzles little bit less seal, but can be used. In most cases, it cannot be used as a replacement for a broken plastic nozzle.
