GMT P90 Aluminum O-ring Air Nozzle (20.83mm)

These aluminum nozzles with O-rings for P90 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 20.83mm (0.820in)
- Inner diameter 5.50mm (0.227in)
- Outer diameter 7.24mm (0.285in)
