If you want to be efficient in this regard, equip an optic on your weapon and go headshots to unlock the camouflages. Assault Rifles, SMGs, and LMGs require 100 headshots for their Camos, while Rifles and Sniper Rifles require 100 one-shot kills for their camos.
Each optic instead requires 500 kills with the aim to unlock the various reticles. Each weapon and optic has camos and reticles that can be unlocked beyond these requirements, but are only available after completing these challenges. It is precisely these unlockables "endings" that they earn large amounts of experience points, so it's definitely worth working on over the course of your games. You'll also get a significant XP reward for unlocking Specialist costumes that are obtained simply by killing and using the Specialist's weapons and skills. Then find the specialist you like and go for it to unlock his costume.
