I’m with Charlie on this one. It seems that this incident proves that 10.5.19 needs to be worded to specifically prohibit looking into an optic at all, not just “sight picture “ if that is what is intended. The “e.g.” is what introduces different “interpretations” of the rule, and I suppose at that point it is up to the RM, but still should be clarified if it is something that happens often and is allowed in 3 Gun. We want to be inclusive, right?
