Would a hop-up upgrade be the entire hop-up unit (CA Sportlines use a plastic unit; I've heard metal units are better) or just the rubber hop-up bucking that goes on the barrel?

I regularly clean my airsoft gun barrel after each use with the supplied cleaning rod, a couple cut-out strips of paper towel, and a little bit of airsoft silicone oil. I always make sure my hop-up is set completely off before I do my barrel cleaning.
