What spare parts do you guys keep on hand during matches? I shoot a lot of AR15 matches and I always keep a kit with spare lower parts, bolts, firing pins, etc... I've never brought any spare bolt gun parts with me to matches though, and fortunately I've never needed any parts during a match. I figure it might be prudent to keep on hand some simple spare parts. What kind of bolt gun parts do you guys keep on hand for match shooting in case there's a problem? Specifically, I'm interested in Rem 700 parts.
