GATE EON CNC Hop-Up Chamber for M4/AR15 AEG

If you are building out your M4/AR15 AEG for maximum performance the Gate EON HOP-up unit is probably already on your list! This precise HOP-up unit is constructed from CNC machined aluminium and is a rotary style unit which applies pressure directly to the top of the HOP-up rubber/nub to minimise side-to-side deviation. This unit is compatible with M4/AR15 AEGs and can also be used with HPA setups thanks to the included nozzle sleeve which perfectly centres the nozzle for maximum efficiency.
