In my AR, I will only use custom cartridges, made from the finest gilded brass.
This brass is imported from the south of madagasgar,brought to me on the backs of baby sea turtles.
Projectiles of the precise atomic mass and electromagnetically inspected by deaf mutes in russian orphan domiciles.
Finally the propellant must be of such strict pureness it is blown into the cases directly out of the rear end of angels.
Then, and only then! will I allow the brand new in the box, untouched by human hands, made in Mozambique by local orangutans with work permits, ammunition to grace my chamber.
