the top one is a RRA bolt I got from a RRA b/c/g and sold the carrier. Now the bolt is for sale. It has only been fired a few times.
the bottom one is a M&A bolt from a carbine kit that has only been test fired from M&A. Both are in like new condition. $55 shipped for each or you can have both for $100 shipped. M.O is best but I can use paymal. Email me at email@example.com of IM me. thanks
