Q: Who’s it for?
A: The 3GN Divisional Series is for the very best 3-gunners in the country. A continuation of last year’s series sponsored by Hornday, the 3GN Divisional Series will name the “Shooter of the Year” in five different equipment divisions: Tactical Optics, Open, Tactical Iron, Heavy Metal and Heavy Metal Optics. Also, the top five competitors in each division at the end of the season will be invited to shoot in the 3GN Pro Series Qualification Match.
Q: Why are Pro Series shooters allowed to play here?
A: Just like last year, the Divisional Series was developed to reward sustained performance over the course of a season in each division—to determine the top shooter in each equipment division. The Pro Series developed after the debut of the Divisional Series last season. To give more shooters a chance to play, 3GN launched two (2) additional levels to the 3GN Outlaw Series—Semi-Pro and Amateur.
