The Elite Hop Up Chamber is the ultimate precision machined CNC hop up chamber designed for VFC based AEGs electric airsoft guns.  

This chamber takes all the elements of the hop up system to the maximum, greatly increasing the performance of your airsoft gun and airsoft hop up.  

Lightweight aluminum is used to fashion this chamber and it is completely machined in Japan.  The lightweight yet robust aluminum is precisely crafted allowing for superb consistency.  Along with its construction, the hop up dial uses a ball-bearing and spring for a positive "click" sound when you make adjustments.  

This design not only allows for very precise adjustments but also holds your hop positon in place even under heavy use. 

Our hop up buckings are designed to fit our EG barrels perfectly.  Mating our barrel and bucking with this CNC hop up chamber ensures exceptional air seal which translates into jaw dropping results downrange.

With the inclusion of two buckings, you can choose the original Prometheus purple bucking for under 350 FPS on .28g BBs or the Prometheus blue 60 degree bucking for 350+ FPS on .28g up to .32g BBs. Build your AEG to the highest standards with a Prometheus ELITE CNC chamber, bucking and barrel for optimal performance!
