ZCI Aluminum MP5 Nozzle (20.40mm)

This is a aluminum nozzle with O-ring for MP5 series rifles. The O-ring stops air from leaking between the cylinder head and nozzle, stock nozzle don't have this. This can increase FPS quite a lot depending on how much air is leaking. Since this doesn't put any more stress on the motor this won't affect your rate of fire like a stiffer spring or spring spacer.



 

Features:
- Aluminum construction
- O-ring increases FPS with no loss of ROF
- Total Length: 20.40mm (.807 in)
