hello all... brand new member here, this is going to be my first post. i ended up with an M60 bolt in a purchase of a gun parts lot from anti-gun ebay of all places. it is unused and in mint condition. found some markings once i got the goopy cosmo off of it, it has mfg date 8/2003 and cage code 3W544 (which looks to be for LMT) along with some other numbers stamped on it. there is an "M" in white paint with what looks like a hardness test dimple above it. i know next to nothing about the M60. can someone tell me around what it is worth? thinking about taking it to the next gun show to trade for something, just wanted to make sure i don't get taken advantage of. thanks.
