I like that they drop randomly gives reason to check out what's going on everyday and stay active, but I don't like how they are only one day, a lot of people may have work or homework and it would suck to miss a gun just because you had to do something that ONE day. I think the quest should get to a certain point that you have to do in one day, but when you reach that point you can do the rest and get the gun WHENEVER you want.
