The MW3 Armory Unlock system grants you access to new weapons, attachments, perks, equipment, killstreaks, and field upgrades as you progress through the game. It becomes available once you reach level 25, and allows you to prioritize unlocking specific items you desire. Here's how it works:

Armory Unlocks: Challenges to unlock weapons, Equipment, Perks, Killstreaks, and cosmetics.
Upon reaching Level 25, a new level of content opens to the player. Armory Unlocks give Operators the ability to unlock more items for their Loadouts, but instead of earning this gear simply by leveling up, players must complete specific in-game challenges to access them. Consider looking through your Loadout options at this point to see which items you can unlock, as well as the challenge required to unlock them.
Unlocks for Level 25: New Feature.
Armory Unlock Challenges are a new system that lets you unlock the Weapons, Equipment, Perks, Killstreaks, and Attachments that you want to utilize. This includes many attachments unlocked through Weapon Progression.
When you reach Level 25, expect to unlock the Armory Unlock Challenge System, and begin to progress and complete challenges, unlocking new items. There are a variety of items you can earn through Armory Unlock Challenges, which you can view in the Armory Unlocks Challenge Menu.
Armory Unlock Challenges are completed by Completing Daily Challenges. Each Daily Challenge completed earns you a point against your active Armory Unlock Challenge.
While you can continue to earn Armory Unlocks in order, you can also “Activate” any valid item. This will now be your Active Armory Unlock Challenge, and you will begin to earn points against it as you complete Daily and Bonus Challenges.
If you complete all your Daily Challenges, you unlock a Bonus Challenge that is unique to each game. Bonus Challenges can be completed infinitely: in Multiplayer, they require winning a match, in Zombies, they require completing Contracts.
If you change your mind mid-completion, don't worry - progress against Armory Unlock Challenges is saved when you Activate a new Challenge.
Remember: If you see an item you want at the end of a Weapon's Progression, then check the Challenges menu; you might be able to unlock it with an Armory Unlock Challenge!
