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.

That bb chopping issue seems prevalent in most WE or like bolt design based rifles. After you replace the hop up sleeve and nub, I would suggest trying semi only, perhaps you will get some wear in to the parts. From what I've learnt in the airsoft world, some wear to get part seated is good. Now, to deal with the lube debacle, there is something I personally use and field on any of my guns; a lot of you may find this either controversial or insightful, to each their own but it's worked for me from air pistols to AEGs with great results, I use Trinity Super Silicone light weight shock oil, this way it's designed to be used on rc car shocks which have rubber damper rings and silicon oil rings, that stuff sticks! You have to make sure to use a light weight rating (also helps with picking out an oil with a lighter viscosity) but you do get a far superior sealing affect that spray silicone. I've used the same on my heavily trusted TM SR16 with a v2 mechbox for the piston assembly and I'm happy to report that I have nothing but success.
