This guide will let you know how to Find & Equip the Weapon Blueprints in Call Of Duty Vanguard & Warzone.
In the main multiplayer menu, you will need to go to the weapons section by pressing the R1 button and then tap on loadouts.
You have to select the custom class option to start the new loadout. Then select my Primary weapon and go to your assault rifles, as shown in the image below.
You will need to select the gun that has an armory option because then you will have the weapon blueprint for that gun.
After that, tap on the Armory button of the gun, and you will find your original gun there. You will see one weapon blueprint next to it, as shown in the image below.
The next thing you will need to do is select that gun by pressing the X button from your controller, and it will become your primary weapon. Now you have to go to a gunsmith, and there you will see that the attachment of the gun is fully upgraded, and it has a great fire range.
Weapon blueprints will provide you with a better gun than the one you will be using right now, with a better attachment that you didn’t unlock for that gun.
