Hop up is still stock. This is the one part I don't really know about. The Bucking is the black rubber sleeve right? I've installed my tightbore so I've had to change barrels. All I did was remove the old barrel, take off sleeve and tiny o-ring on the end of it, replaced it on the tightbore and put the barrel back onto the hop-up unit. Did I miss something here that I might have screwed up??
