loose lens

so I might be buying a laser with a loose lens due to being droped is this an easy fix? Does it affect performance if so by how much? Is there a tutorial how to fix it because I couldn't find 1?

Thanks
Myles

need more info is it a green ,if so those are tricky to repair from a drop

oh yeah my bad it's a 95mw nexus green from WL

I'm not saying it can't be done but i havent mastered it yet in fact i have
a green still mod hopping (showing 4 dots i tried to align the crystals back what a headache usually its the crystals that get knocked loose but if its just a lense that shouldn't be too hard hope this helps i need to get some sleep
