The AR500 is, according to the company’s claims and my own research, the most powerful short-range semi-auto rifle in the world. Chambered in the .50-caliber 500 Auto Max cartridge, the AR500 packs a wallop in a modified AR-10 platform. Combined with Buffalo Bore’s 350, 400, and 440 grain loads, the AR500 is ready to bring down, quite literally, any kind of critter you’re hoping to hunt.
