For the first time, Vang Comp is putting on an armorer's course for the Remington 870 and Mossberg 500/590 series shotguns. The class is being hosted by 360 Performance Shooting.
The classes are offered on different days, allowing you to take either or both as it suits your preferences. With the combination of Vang's shop foreman and the number of good shotgun instructors who are coming from across the country, it will be quite the gathering of shotgun knowledge.

Mossberg 500/590 Armorer's Class
With Remington's woes, knowing how to keep your own 870 running would be a good idea.
