Our take: This is the factory replacement Air Nozzle for the G&G GR16 M4/ M16 Series AEGs. The Air Nozzle is made of durable Nylon Polymer, and forms a perfect seal over the cylinder head. G&G's factory replacement air nozzles allow maximize air compression, ultimately leading to more power for your AEG. This air nozzle can be used as a replacement for most M4/ M16 Version 2 metal gearbox AEG, however universal fitment is not guaranteed.
As with all internal Airsoft upgrades, professional installation is highly recommended. Airsoft Megastore is not responsible for any problems that may occur when installing this factory upgrade part.
