Best aeg hop up for heavy bb's

I have built a dmr @450 fps on .2 bb's, after some testing with different buckings I have noticed different joule outputs when applying hop. Especially when applying the correct hop on .4+ bb's.

Also mentioning, the gun is built to have slight joule creep for assault class which is 350fps/1.14J on .2 and i have 1.45J on .32 bb's but with easy change of a longer barrel i can play @450 fps on .2 bb's which is dmr class at my field.

So my question is what is the best hop up bucking/style for heavy bb's. Do you guys have some results to share or any suggestions? Currently i'm using a maple leaf macaron 60°. The joules i have with it is, 1,87J on .2, 1,91J on .32 and 1,79J on .4 bb's.

I have ordered this, the Snipetor PDI Black Raven Rhop 65º to try out, maybe this could retain my joules better.

Typically R-hop keeps your Joules higher. It takes less hop to get the correct backspin. But to get that magical install is tricky.

I'm still a fan of the good old Prometheus Purple bucking.

Never used the fancy maple leaf stuff in AEGs. Though I have an Autobot in my MK23 pistol and that is amazing.

Do you think 50° is too soft for 1,9J, like will it rip apart after a couple shots or will it hold on for a couple 1000 shots?

What is the problem with the macaron 60°?
R-hops can easily hop heavy bbs. If you´re still not happy, you can use an ER-hop.

The problem is that the macaron needs too much hop for a heavy bb, i lose too much joules with it. But I have already solved the problem.

I have now changed it for a prometheus purple with a concave nub. Now i even have more joules with a .4 than a .32 while before i had less joules with a .4 than a .32

Have you tried a different, harder, nub? Try that, you may get better results with the ML.

Have you used a concave nub with the ML bucking, or just the stock nub?
Also, the prommy purple is designed to be used with cylindrical nubs, not concave ones.
I´d say there´s something wrong in your hop up system, if you´re getting more hop with a standard style bucking than with a ML.

The prometheus purple is flat hopped maybe i should have mentioned that. All the nubs i use are very hard, most of them are plastic, cnc or a hard type of rubber.
I only use concave or flat nubs i have tried both with the maple leaf but the flat hopped prometheus purple with a concave nub performed better.

I always go softer, more grip for less hop. They do wear out faster. But its a cheap part. In saying that though its been a while since I've used buckings in my hi-powered gun. Normally I'm using an er hop, time-consuming to set up, but if you nail it. BBs look shoot like lasers.

Plazaburn has a point on nubs. If your finding that you're not getting enough hop the that's one place to start. Though you've said you sorted it with a Prommie bucking and concave nub. Thats, not the first time I've heard of the ML aeg hops being hard to work with, I must get one and try them out.

I'm interested in the nubs you've tried. Im always keen to see what techs are trying.

Yeah my experience with AEG ML's has been mediocre, too. I see them as better than stock, but far from max performance.

My experience with ML buckings in general is that:

1. All the buckings run small on the diameter. Every last one. Most require tape to function.

2. Results are all over the spectrum from amazing to shit, with little to explain why there is a difference. Visual inspection shows no anomalies.

3. Bucking lips too large to seal properly. This primarily effects the hybrid buckings and AEG buckings.

============
The best performing ML bucking I have used in a platform outside of a bolt action or pistol, has been a macaron 75 on a edgi 363x03 barrel with coupled with a MaxxModel hopup unit. (Current ME version.) Using a modified 4.5mm rhop nub included with the unit.

I've been loking around for some hop up methods and come across to j and s hop. They seemed quite interesting to do and cheap too. Does anyone has experience with them and which is the better one in therms of performance and durability?

Also is there a difference in brand or some requirements of the product i need to look out for? Like how can i distinguish the difference of hardness of the material when dried at looking to the products specs if i don't have the same brands over here?

Well, I have experience with s-hop. It works, but your mileage will very depending on how well you kneed and mix the material. Then you need to make 110% sure you turn your hop up off after every game day. If you don't, you ruin the patch and have to redo it. Heat will effect this as well.

I've experimented with S-hop. Easy to do, but I wasn't seeing an equal performance in terms of range and accuracy over a decent rubber patch and a well-shaped nub. Nor did I find it performed any better than a normal bucking. Though that could be user error.

From what I've learnt/experimented with if you are using a standard size hop window, a normal bucking will be the way to go.

If you are looking to save joules lost when adding hop on something that you're really trying to push Joules up. An ER-hop of some kind is the next step, so cutting the barrel window, cutting a patch, modifying a hop chamber and making a nub. A lot of work, and some very fiddly work.

1tonne has had a lot of success though with normal buckings and retaining joules in a AEG. I can't quite recall his process.

Hmm maybe not the way to go i want my gun to be reliable.
So if my r hop patch ever wants to arrive (they delivered it to the wrong adress...) and i'm not satisfied with the result i may try an ier-hop.
HSA IER-Hop Z-kit - Recoil Airsoft are these patches any good? HSA EM-Nub in combination with this nub?
Then i can practice to cut the window to the length of the patch on cheap barrels, will a dremel be good enough for it? And which glue or other type do you recommend to secure the patch in the window?
