I know right? People love customization, whether it be character or weapons. It gets interesting with modern weapons because a lot of us have that "weapon fetish" where we like to deck our guns out with specific details. And that's why I'm so disappointed that different upgrades in Destiny didn't add anything to the weapons outside of scopes. (Hipefire upgrade adding a sweet laser sight or field scout/extended changing the mag into a drum, different chokes on shotties and LMGs actually changing the appearance of the barrel, etc.)
