I'm going to be upgrading my G&G CM very soon, and I'm looking for a high quality, long-lasting hop up unit. I'm looking for serious answers, and it would be nice for people to give their past experiences. I'll also be doing one for buckings soon. Thank you  |

To be completely honest, the stock combat machine hopup really isn't that bad. It can benefit by cutting a toothpick and putting it in the nub to make it a bit stiffer though. Its also a good platform for the rhop. Believe it or not, I've had the best results rhopping with the stock hopup, stock bucking, and stock nub with a toothpick in it.
Modify hopups aren't too bad. They require a bit of tweaking to get them into that sweetspot.

It works great and it's a very durable unit. I'm planning on adding a r-hop to it in the near future. But it will definitely reach out there without it.

I didn't vote because this is too vague. There is no "best" hop up unit out there stock. The purpose of a hop unit is to provide airseal, feed the bb and apply hop. All of those will do so in some way or another but with varying degrees of consistency depending on the bucking and how it was installed.
Ideally you would have an r hop, in which case you can run a hard bucking (lonex are cheap and great quality) for good air seal with the nozzle. You can use RTV to seal the bucking to the barrel on the muzzle end.
If you do those two thing, you just eliminated air seal from the equation and now the chamber just needs to feed and apply hop. Most have zero problems feeding as long as they are in spec. As far a maximum consistency when applying hop you want to eliminate side to side play in the arm. If it doesn't come like that then there are mods to do so.
The madbull and pro win both have those nice big wheels that apparently don't slip, but I've honestly never had issues with a regular m4 unit's dial slipping if you tighten the screw nicely. Also I think a lot of people have issues fitting brands of buckings other than madbull in the MB ultimate chamber since they make it tighter for their thin buckings.
I guess one more thing you could add is overall fit and finish. It is nice to work with nice looking and feeling parts that all fit together nicely. I personally find that it makes the job more enjoyable.
Right now I have a Lonex chamber I a working on for my r hopped barrel group. The fitment of the parts are all really nice and the shiny finish is great looking. I haven't tested it yet so I can't really comment on it in the other categories just yet. Mine was only $11 or something from WGC.
If you can tell us more about your setup and how you intend to run it and if you are doing any mods then that would be helpful.

Ctres, For now; I will simply be running a stock CM. Eventually I'll consider a nice Rhop, but for now I'm looking for what's worked in the past. Since I've only used stock hopups I'm at a loss here.
Let's just say that my main two points of interest are consistency of hop and durability.
I'm planning to use it as an M4, like a standard assault rifle. Accuracy is a big deal, and I'll be getting a tightbore along with this upgrade.
Squirrel; I have noticed how flimsy the nub is, so i think I'll try that out.

Hop up units don't really break under normal use so I wouldn't be worried about durability. It would be easier to break it during dissassembly than during usage.
In regards to the hop up system, consistency will come almost entirely from the bucking and the way it seals. I would say to get a primmy purple bucking and prommy EG 6.03 barrel before shelling out for a hop up. After that, if you still think something is lacking, then go ahead and get a hop up unit.

Squirrel; I have noticed how flimsy the nub is, so i think I'll try that out. I think you'll find it improves consistency for a basically free mod. I've also used a large diameter paper clip in the nub, but it didn't improve anything over the toothpick. The toothpick is easier to cut, so I'd go with that. |
