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....
