Failed to fit the Madbull outer barrel.
Some modification was needed.

This right here is it. This chamber provides excellent air seal and very convenient hop-up settings. However it's impossible to use it with an SDG or M-block, so be aware of that.

As a technique i first try it to my guns...now i put it to everybody. Very good seal from other brad names like madbull,prometheus,king arms...e.t.c. Upgrade fps,the 0,20 now to my g&p send to 80m with nο adjustment. Not just value for money.The best hop up to the best price.

Bought this to replace the g&p hop unit that was in my gun, as some people may know g&p hop units aren't the greatest. Ordered this hop unit with a prometheus rubber and element h-nub. all the items work great together and required no modification to fit my g&p m4. All in all great product and great service.

This unit beats all other standard M4 hop-ups out of the water with its ease of installation and set-up. Like the other reviewers you might need to make some mods for various inner barrels (my method involves a slightly smaller cylindrical piece - maybe a small screw driver - wrapped with 400 grit or finer sandpaper to 'bore-out' the chamber. You basically just want to have the bucking and the inner barrel fit.

Minor adjustments are a easy to make. If you change to a longer barrel it takes under a minute to break down.

I've paired this unit with a Maple Leaf Diamond bucking @70 degrees. It shoots very flat with tight groupings.

First I will say that this hopup unit can be considered overkill and it is possible to finely tune a traditional M4 style hopup to be very accurate. However, this thing is awesome and the CNC machining is perfect. This combined with a high quality bucking and nub/spacer with make any M4 awesome. This hopup combined with a Prometheus Purple bucking raised my fps and accuracy. My gun went from 404-410 fps to 435-440 fps.

Pros
- CNC Machining makes this thing super precise
- Anodized blue finish! Shiny and adds a little splash of color to any gun.
- The dial offers the ability to finely tune the hopup with minimal adjustments and it will stay put too.
- Easy to assemble like the traditional M4 unit

Cons
- Like all Hopup units, it may not fit all outer barrels due to the size of the fins on the sides of it.
- No stabilizer spring offered like traditional M4 units available on the market. This can be an issue if you don't already have one or the spring from you other unit doesn't fit.

Installed this with a Madbull 7075 barrel and am getting excellent results.
Unit has very fine adjustment, very precise machining, and is very good value for money.

Beats all other hop units I've tried.
