Hoping someone can help me understand what sights to use shooting at the Friendship Nationals. Several of the Aggs: C, E, H, M, just to reference a few, specify "open sights" for half the matches in the Aggregate and then "any metallic sight" the other matches. As I understand it, AMS can mean peep sights. Is that correct. Is so how would you shoot that agg? Would you use two rifles? One with peep sights and the other with open sights. Or use one rifle that can be switched from open to peep sights? Guess it's pretty obvious I've never shot at Friendship.
