Hey guys,

I'm currently working on a sniper rifle game, well the menu and stats screen at the moment and have 4 stats bars for each rifle (range, recoil, mag size and mobility) will be 5 soon when added rate of fire. Each rifle has different stats and the range bar (for example) will be different widths for each rifle. If I wanted the scope add on 100 pixels of width to the range bar no matter what size it currently is how do I go about it?
