While I like the ingenuity that went into this, it does have several flaws.
Cutting the bucking requires extra room for it to be glued to the side of the barrel. Many chambers won't like this, as they're already pretty tight around the bucking. Using something like a rubber band is even thicker, and will have even less room.
The extra long wings do help with a problem the G-hop had, with it ripping off and jamming in the barrel. The extra contact keeps it in place.
There are ways of fixing your hop, but I don't believe this is the way to do it. I see pinching being a problem, having it too tight and giving too much hop. I suppose once you get a feel to it, you wouldn't have to redo the hop so often. But then you're locked to one specific bb, which is a problem imo.
