A replacement Hop-up Rubber Nub for the Action Army CNC hop unit. This is the part that is pushed into the bucking (rubber sleeve) that surrounds the inner barrel and pushes the bucking down inside the inner barrel to reach the top of the BB being fired to create back-spin (Hop-Up).

The nub shouldn't need replaced that often - if at all - but can deform through constant pressure and become oval shaped instead of round, therefore less effective. Ideally your hop should be dialed off completely after each game day, the same way you should make sure your AEG spring is decompressed to avoid loss of spring tension.
