Unicorn's 70 Degree AEG hop-up bucking is a firm rubber sleeve for hop-up chambers on AEG inner barrels. The 70-degree hardness suits a gun making real power, because high pressure would deform a softer compound and a deformed bucking can't apply consistent backspin. It also pairs with heavier BBs, which need more grip to take the same spin. Match the hardness to your gun's power rather than assuming firmer is better; a 70 degree in a low-powered AEG will grip poorly. Fit it square on the barrel window with no twist, and check the nub presses evenly across it.
