GMT G3 Aluminum O-ring Air Nozzle (21.28mm)

These aluminum nozzles with O-rings for G3 replicas are a great way to increase air seal and in turn FPS. The O-ring stops air from leaking between the cylinder head and nozzle, nearly all stock nozzles lack O-rings and many are quite loose. Due to the poor tolerances of many stock nozzles an O-ring nozzle can dramatically increase the FPS with no ROF penalty like using a stiffer spring.

Features:
- Aluminum construction
- O-ring increases FPS with no loss of ROF
- Total length 21.28mm (0.838in)
- Inner diameter 5.62mm (0.221in)
- Outer diameter 7.11mm (0.280in) (front section)
