>>11147784.22LR ammo is more common than 5.56 ammo now due to panic buying. It's actually a good choice.
I personally would recommend a .45-70 for its stopping power, and the relative availability of ammo for in the current market.
Pic related is a Henry X model .45-70 that has fiber optic sights iron sights for low light visibility; and also a picatiny raile and 2 M-locks for mounting flashlights and lasers. I'd say a flashlight is a necessity on a gun, since most of the nigger/commie rioting happens at night. If you don't have a gun with rails, M-locks, etc., then at least duct-tape a flashlight on the barrel somewhere.
