What's A Hop-up Bucking?

hi there, im looking at new hop rubbers and i just came across buckings... what do they do? how do you install them? any other info would be appreciated (Pictures and diagrams will help too)

Thanks,

buckings are a small softish plastic/rubber component inside the hop up

The hop up arm presses on the bucking which presses on the hop up rubber, which directly contacts the BB

Different shaped ones exist for different uses (a H-nub is H shaped to add pressure on both edges and not the middle, much more effective for single shot, but makes no differnece in an auto weapon like an M4 over a normal bucking)

also, remember to add these back into the hop up, it is fiddly, but the gun won't hop without it!

they can just be plain round right?

cus something fell out my gun last night like that...

were does it sit? in the bit which presses the hop rubber up?

are X buckings any good? the madbull ones
