The JBU M4 Air Nozzle creates a tighter air seal that ensures greater muzzle velocity when the BB leaves the barrel. The JBU series of upgrade parts are compatible with most major brands of AEG. You can expect the same level of quality from these parts as Guarder and Systema parts for a fraction of the price.
I've been using this nozzle for a while after my old one got a crack in it...
It looks like it's metal, but it's really just colored plastic. Was simple to install and is pretty strong.
If it was metal, they would probably be advertising it as metal...
Simple and works like it's expected
Not metal like it looks
