Owen “Buz” Mills is the owner of Gunsite Academy, a weapons training facility for members of the armed forces, law enforcement and civilians. Instructors at the facility teach the “Combat Triad,” a firearms discipline focusing on marksmanship, gun handling, and mindset. Shooters who take a two-day class are given a complimentary NRA membership. Courses offered by Gunsite also include a five-day urban sniper course, a “battle rifle” course and a foreign weapons course. Mills is also a former political candidate. He spent $2.3 million as a Republican candidate for governor of Arizona in 2010, before dropping out prior to the primary.
