hi i need some help i just installed a new mad bull tight bore and new guarder sp 110 spring with 9.6 bat and i need help because my gun does not shoot straight from 30-beyond... is this right? i think my hop up is the problem but i don't know how to fix it. i guess i just need to tune it up but i cant seem to get it shooting straight pass 30-40 feet... Max range is 120 ft right? Please help.

No the nub that sits on the rubber and is pushed down by the yellow lever.

The hop-up nub is a tiny little part inside your hop-up housing/unit. It sounds like you may not know your way around the inside of your gun. I don't want to assume inexperience, it just seems like it from your posts...

the tiny ruber cylinder that fits in the slot on top so you have to flip the hop up unit upside down to insert it and it has to be a perfect fit too and it has to fit sideways like a hot dog in the chamber.
