ICS L85 Hop up causing bb's to fly off to the right

[Stones]

I don't really post on here often, but I have a problem and my normal forum, Zero In, is down for a week or so...again. Anyway, here's my problem. The hop up arm is pushing down the left side of the nub more than the right side, causing bb's to fly off to the right. Not sure if I could just replace the hop up and it would be fine or whether I could make some small adjustments to the hop arm in order to get it to either sit correctly or put pressure on both sides of the nub. Or, what i'd really like to do, but would probably be impossible would be to mod a Madbull ultimate hop up to fit inside and replace the current stock ICS hop. So does anyone have any ideas about this?

Easiest fix would be to twist the hop unit slightly to the left. Otherwise I would have a look at your hop nub as it might not be square, so you could shave a bit off the right hand side of the nub.
