Prometheus ELITE CNC Aluminum Hop-Up Chamber for Airsoft AEG Rifles (Model: M4/M16)

"Alright so I am the fool who purchased both the marui hop chamber and the vfc version. Both are very nice. Are they worth the price? Definitely not. I like to always try new parts regardless of the prices, especially now in America. The only differences I can see between the two variants is the hop wheel. The vfc wheel is smaller. I test fit the marui version inside a vfc saber, and it fit and worked fine. The small spring and ball bearing is a nice touch, and you can feel and hear the click into place for that exact turn of the hop wheel. I tried a maple leaf super macaron silicon 70 bucking and omega nub with both units, and both seemed to apply alot of tension on the nub even when the hop wheel was turned all the way off. I am currently using the new blue bucking and nub that is included and seems to provide good seal.
In the pictures here, you can see machining imperfections inside the inlet of the chamber as well as the roof inside the chamber.... Not a big deal and has no ill effects on clearances or feeding.
Does it perform better than the Prowin or Maxx Units? nope. Would I get another? Most likely not, but I do recommend it if you are into trying out new parts and like to specifically use the Prometheus brand. It looks great inside the receiver of my vfc and marui platforms, but most importantly it is about function over form, and for the money you can get the same performance for a lot less with the competition.
