The ProWin M4 / M16 CNC Hop Up Chamber is a great upgrade from your AEG's stock plastic, or weak cast metal hop up chamber. Metal hop up chambers are known for providing a better air seal against the AEG's gearbox, and feeding much more smoothly than plastic chambers. Many cast metal hop up chambers, however, have weak areas in the metal from the casting process, but this problem is completely eliminated with the ProWin chamber. This hop up chamber is machined completely out of aircraft grade aluminum, meaning it is both lightweight and durable, and the bright blue color helps give your AEG a custom look.

Specifications:
Manufacturer: ProWin
Model: M4 / M16 CNC Hop Up Chamber

Product Information:
I use a VFC SR15 and this by far the best I upgrade I have gotten for it. With a Flat Hop you will see an improvement in range and accuracy and a slight bump in FPS. The package I received didn't come with instructions but there are a couple of youtube videos to show how to put it together.

I just ordered a Miracle Barrel to go with it so I can't wait to see how that combo works out.

Pros:
Really improved my range and accuracy using the stock VFC barrel while using a Flat Hop nub and Bucking.

The adjustment wheel is very stiff and will hold your adjustment. So no having to fiddle with the hop up every time you go out to play.

Cons:
When I ordered it the lack of instructions was a problem.

Product Information:
I run these and Modify hop ups in all of my M4s. I absolutely love both of them and have never experienced problems. Love them. Definitely the best rear-wheel M4 hopup on the market. Far better than the MadBull hopup. The Madbull is a joke compared to this. If you're thinking about spending the money for a MadBull, just buy this and save yourself all of the trouble that the Madbull will give you.

Pros:
-Amazing air seal with buckings
-Stays on barrel tightly with no wobble
-Looks awesome
-Very high quality materials and finish
-Over all very high quality
-Never loses its arm position or hopup tension
-Best rear-wheel M4 hopup on the market
-A million times better than the Madbull
-I cannot even stress how much of a joke the MadBull is compared to the ProWin
-No issues

Cons:
-Set screw for hopup spring and be a little difficult but easy to figure out
-NO Cons
