GMT MP5 Aluminum O-ring Air Nozzle (20.37mm) (Flat Nose Version)

These aluminum nozzles with O-rings for MP5 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. Unlike most nozzles these have an extremely flat front, this means the nozzle can be a little shorter than an equivalent tapered tip nozzle, there is also some evidence to show flat faced nozzles seal better.

Features:
- Aluminum construction
- O-ring increases FPS with no loss of ROF
- Total length 20.37mm (1.115in)
- Inner diameter 5.62mm (0.221in)
- Outer diameter 7.11mm (0.280in) (front section)
