GMT Aluminum MP5 O-ring nozzle (17.81mm)

This is an aluminum nozzle with O-ring for MP5 series rifles. (note: the MP5K uses a different gearbox, V3 rather than V2, I own a Galaxy MP5K and the SHS M4 nozzle was is the exact correct length, but to make it fit you need to bore out the hopup chamber from the feeding tube back to the gearbox connector) (note 2: I have been informed that this nozzle does not fit the ICS MP5 as it is a few mm too short, this is because the ICS MP5 uses a different size nozzle than a TM or TM clone MP5.) The O-ring stops air from leaking between the cylinder head and nozzle, all 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.
