I recently ripped my last hop up rubber for my rifle, (stock ASR), and decided that I would try an AEG bucking instead of waiting for a couple of weeks while a new one ships (I also have a game tomorrow). Because of the barrel cut, the bucking was placed upside down, where the little lip did not sit in the bucking, but on the opposite side, creating a bulge (I also cut a few mm off the end so it would fit). This leaves the hop up profile like
_||_ instead of _/\_ or -<>- when the barrel cut is _ _ and the bb sits here -> *.
Since none of you will be able to figure ^^ my code out, I'll make a sketch tomorrow. I was only able to shoot ~15 rounds due to failing light, but it seems to work fairly well, with a maybe 2 jams and one flier to the extreme left. I'll test further when I have some more light tomorrow, and post results here.

Any bucking that causes a jam needs to be looked at. Even if you could get 14 sweet shots and one jam per 15 shots, I would still be hesitant to use it on the field.

Due to today's severe thunderstorm, I cannot test any further. And Fuzzy, it's more of a 'I'll try it and see what happens' thing. I know why it jams, because the amount of rubber that can potentially hop the bb is, well, a lot. It basically double feeds, but removing the mag and cycling the bolt clears it out. Again, I can't accurately describe it because I haven't fully tested it. Basically, all I know is that it has some hop, and you can shoot bbs out of it.

Lain I know exactly what you mean. I tried a AEG bucking in my stock UTG mk96 chamber, and noticed a large amount of nub showing. Like newbie said, a hard bucking would probably help solve the jamming issue, as less nub will be pushed down (or at least not as easily).

Well, right now I'm using a stock bucking that came with one of my aegs (its black). Seems to be very similar to a Guarder Black, which will probably be the bucking I use if it works out for me. Right now its just in, no shimming, adjusting, etc. I only got another mag (~25 rounds) through because the whole morning there was a freak storm that tore up a lot of trees, todays game got canceled, so I didn't get much shooting time before it got dark. I had a jam on the first round, after that it was fine. About 1/2 of the shots were straight, flat trajectory (100ft testing only), rest were slight left hooking (only ~1 foot @ 100ft), with 2-3 crazy left/up shots. It was actually pretty nice, considering: new bucking (not worn in), no scope/aiming (down the barrel/rail only), and slight gusts (after affects of the storm). Good enough that I would have been satisfied using it if I played today.
@Fuzzy- actually, the bump on the bucking is not used for hopping.
I'll draw up a diagram later (too lazy to do it now), but the little 'rail' on the rubber that fits in the barrel groove is applying hop, because my stock barrel has the barrel groove on top. I did this because it seemed to have a better seal. Again, I'll draw up a diagram later.
