DESCRIPTION

Modify Air Seal Nozzle for M16A2/M4 Series Airsoft

Modify upgraded AEG air nozzles feature an extra O-ring to minimize air loss between a cylinder head and a hop-up unit.

The AEG air seal nozzle is the device between the gearbox and the hop-up unit that loads BBs into the hop-up in preparation for firing an airsoft gun.
