This is a great idea!! Why not make sights like an extra piece of loot.....I like this sight but not the gun it's on.....and I like this gun but not it's sight.....put the sight from the first gun in my general inventory spot( or add a weapon parts section) and break the gun down for weapon parts and glimmer. Now take the sight off the gun I like and break it down for weapon parts and glimmer, then take the sight I like out of my inventory and put it on the gun I like! This, though, with all Destiny's glitches seems way to complicated for them to pull off!! Lol
