BO4 Annihilator Revolver
Immediately, I can say, that this is not to be confused with the one tiktokfamous made! Compare between the two, get his mod!
This is a grounded revolver using high caliber rounds enough to one-tap sosigs the same way it would in BO4 lobbies. 45-70 Government is goated, I've used it before with the Donner revolver (blessed by NotColin with his model) and it feels like more revolvers using this same ammo have been coming out. Am I wrong? I could be wrong.
