Hey gang, looking for some help and clarification on the rules. I'm considering a 30-40 Krag carbine for BAMM side matches. How can I be sure this thing hasn't had any external mods that would render it unacceptable for use? I'm not really a military bolt rifle historian so I couldn't tell you if this carbine is "as issued" or if it's been cut down. Or am I just reading too much into the rules on this one?
