Weapons in Call of Duty: Modern Warfare have a lot of levels

Weapons in Call of Duty: Modern Warfare have been updated with a new leveling system that offers deeper progression and customization than ever before seen in Call of Duty. 

Each weapon in Call of Duty: Modern Warfare has between 50 and 71 levels to progress through. The level varies based on the weapon. For example, the P90 has 50 levels; the M4 has 71 levels. 

You level up weapons in Call of Duty: Modern Warfare by just using the weapon in game to earn Weapon XP. While leveling up weapons in Call of Duty: Modern Warfare, you also get bonus player XP. 

Leveling up weapons in Modern Warfare unlocks two different things: certain levels will unlock new attachments to use in the Gunsmith, and other levels will unlock new camo classes in Modern Warfare.

All attachments in Call of Duty: Modern Warfare are earned through leveling up the weapon and can be equipped in Gunsmith, similar to the beta experience of Call of Duty: Modern Warfare. 

Weapons have 100+ attachments options, the most in any Call of Duty game ever, allowing for a deep customization and weapon changes that Call of Duty has not seen before. You can make a variety of new weapons in Gunsmith and save them as you want. 

Call of Duty: Modern Warfare also features cosmetic weapon variants. The cosmetic weapon variants have different looks with a set of attachments that provide a different feel to the overall weapon. Cosmetic weapon variants can be earned through completing objectives, pre-order bonuses, and more in the game.
