also what is that small piece in from of the bucking in that picture? and where does it go?
thats hopup bucking nub.... (see pic)



that's the part that pushes the rubber down,

The small spring pushes the hopup unit backward, for a better airseal, and also acts like a bumper, each time the piston slams forward (energy transfer...wont get into deep physic explanations here...), reducing wear on your upper receiver, and on the hopup unit itself....
