How to unlock the Armed to the Teeth achievement in PAYDAY 2 - Definitive Guide
When you finish a heist, you'll get to pick one of three cards, that will reward you with either cash, exp, a mask, mask accessory or weapon mod. Once you get a weapon mod from one of these, simply equip it to an appropriate weapon in you inventory by pressing on a weapon that can equip it. Then, simple purchase the weapon mod.
To be able to modify a weapon, you must first unlock a weapon mod from the cards you choose from after a completed job. The weapon mods you unlock through the cards are completely random; this means you might unlock a weapon mod for a weapon you don’t even own. Once a mod has been unlocked for a weapon, that weapon will have an exclamation symbol on it when you're on the buy a weapon screen. Simply choose a weapon you want to customize that has a mod unlocked by pressing to modify weapon; you must then buy the mod you unlocked.
Note: If you have the Lootbag DLC, this includes the red dot sight for all rifles & shoguns, meaning you only have to buy the attachment in the game.
