Wyoming-based gun maker Big Horn Armory brought some big guns to TriggrCon 2018 and didn’t disappoint. At the range, company rep Sam Kuntz showed off the AR500, an AR platform chambered for 500 Auto Max. And wow! That’s a whole lot of nastiness moving downrange quickly.

Kuntz said “this is the most powerful, widely available AR on the market today … out of this 18-inch barrel we’re able to put a 440 grain hard cast downrange at 2,200 feet per second, resulting in 4,500 foot pounds of energy.” He added the 500 Auto Max has the same load data, shelf life and power as a .500 S&W.
