Free Shipping for orders over $179 No Coupon neededNew to airsoft? Here are some safety tips for airsoft guns that we recommend following.
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.

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

Product Information:
PROWIN HOPUP DID NOT FIT CLASSIC ARMY SKIRMISH KM12.
Pros:
Buyer beware. Tried to get the best product based on the reviews here. Searched the internet and all pointed to this being the best. Arrived and it looked great. Very nice finish. Assembled easily.
Cons:
But then it would not fit in the upper receiver. After hours of tinkering and using a dremel tool to get it to fit it shot terribly. Many misfeeds and wouldn\\\'t go more than 50 feet. Worst purchase ever made here.
Do not buy. Label says for Tokyo Marui M4. Airsoft GI was not kidding! Should have been more clear in product description that it wont fit anything else.
Online shopping for after market parts is difficult and this process was not made any easier. Poor directory of what will fit in your gun. And obviously no returns are refunds when you try to put it in your gun and it wont work. I\\\'m looking again now in search of a hop-up unit and everywhere I look there is no description letting me know if it will work in my gun brand. Very frustrating experience.
