Backyard BBQ Blueprint in Warzone is an epic level blueprint for the Origin 12.
Blueprints, both in Call of Duty: Modern Warfare and the free-to-play battle royale Warzone, are custom weapon builds coming with special skins and preset attachments. Blueprints make up most of the world drops from crates in Warzone.
As with most blueprints, you have to purchase a bundle to unlock the weapon construct. Purchasing the blueprint, for newer players who haven't leveled up weapons, gives players access to attachments making the process easier.

The pack will cost 1,200 COD Points and has cosmetics emblazoned with the American flag. The brash colors probably won't help your stealth, but will definitely intimidate your opponents.
The Operator you get is Weekend Warrior, featuring D-Day with an American flag bandana. The weapons you get are similarly loud. The Sparkler Uzi blueprint and Backyard BBQ Origin 12 blueprint both feature the stars and stripes.
