Could anyone out there who's prestiged any of their weapons tell me, do you keep your weapon camo or do they all have to be unlocked again? The weapon prestige description gives the impression that you only have to unlock all the attachments again, rather than the camos, but I'd like to know for sure before I decide.
Your weapon resets to level 1, so you have to earn your attachments again.
You keep all your camos and your progress, so if you had 50 headshots before you prestiged the weapon, you still have those 50, and only need 50 more to get to Kryptek. This is awesome.
