Ah, I know what you are talking about. I looked at the hop up positioning. It looked fine. If I look down the copper tube I can see it there. I took the gun apart this evening the hop up is only 1000 rounds old and it's yellowed and the nub looks damaged. I'm not sure if that's what the hop ups look like when they're "broken in", but it makes me believe that the bbs are chopping in the gun and slicing up the hop up. I also noticed that the little black rubber piece that sits up against the hopup rubber is not perfectly cylindrical. I wonder if that affects the bb's path. Oh and does anyone know what kind of grease I should be using to lubricate the bolt carrier? Silicone oil evaporates too fast.
