New to airsoft? Here are some safety tips for airsoft guns that we recommend following.

The Madbull Ultimate Hop Up Chamber has many features that you won't find on any other M4/M16 hop up. For example, the integrated chamber lock system keeps all of the BBs that are inside the hop up nozzle in place even after the magazine is removed. Also, on the side of the loading nozzle is a place to mount Madbull's LED Tracer system. The LED add-on will be available soon and sold separately. With this revolutionary system you can use tracer BBs with any M4/M16 magazine. Finally, the adjustment wheel has been changed so that it's easier to adjust. Madbull has been and continues to lead the way with innovative airsoft products such as this Ultimate Hop Up.

Product Information:
I bought this product when I was relatively new to airsoft. I did a ton of research and looked at a bunch of forums figuring out how I could increase range accuracy and fps because i like playing the DMR role. Little did I know I had no idea how to put this hop unit together or even take apart my gun. Thankfully the Manuel that came with this product was simple and easy to understand. Putting together the hop up unit was simple the only challenge I ran into was getting the nub to stick I didn't have any grease at my house so I had to go out and buy some which wasn't too expensive at all. Once I got the unit together it was an easy drop in to my G&G Raider... With my inexperience I didn't see too many results at first... But that was because my nub was crooked and my bucking wasn't installed correctly.. Yeah I was such a noob at the time... When I actually figured out the problems and became more intelligent with airsoft parts this unit was awesome. It has instantly increased accuracy and improved range. BB's were finally shooting straight no flyers!! Another huge positive was the wheel. It's very easy to move and since it's larger it's even easier to move with gloves on. All in all this unit has been everything I've wanted and I am going to install it into my new airsoft gi custom DMR.. Pairing this with a magic box miracle barrel and I'm going to have one accurate rifle.

Pros:
Metal!
Great deal for what you get in this package
Tracer unit attachment.. I don't use a tracer unit but it's still really nice
Accuracy increase
Range improvement
Installation easy if you know what your doing
Another great product from mad bull
Only lose one BB instead of 5 when you take the mag out


Cons:
None really
Harder for me to put together but thats because I had no idea what I was doing at the time
This is an awesome product and I suggest you buy one!

Product Information:
I do not recommend this hop up at all. Can be difficult to put into gun and mine came broken and would not work at all. Hard to believe that Gi would ship a broken product.

Pros:
None that I can think of unless you are a collector of broken airsoft parts.

Cons:
Came broken. Hard to put into gun. Don't Buy.

Product Information:
The concept and Idea for this Hop Up unit is great. Building it was fairly simple, just make sure you have some grease on hand for the spacer. The bucking I found was too big for the chamber itself and the metal is really cheap. The front end broke during shipping which didn't surprise me once I notice how this and soft the metal was. I did love how it kept the bbs in the chamber. Little disappointed on the quality.

Pros:
Great Concept
Installing was quick and Easy
BBs did stay in


Cons:
Cheap Metal
Bad Bucking
Nothing else comes to mind.
 
Will this work in my cyma mk12?
I bought a prowin hop up and a flat hop bucking but I've been having some issues with feeding on the prowin, it either jams and doesn't even shoot the bb, or it wont allow my mid caps to feed, will switching to this hop up fix my problem?
