Can someone help me ID these pins. I am putting together a polish underfolder together and trying to figure out where each of these pins go. I think the far left one is for the muzzle break and the far right one is for the rear site. I'm thinking the 3 second to longest are the folder pins and the 4 shorter ones are for the gas block and front site. Will the bent one need to be replaced? or will it straighten out when I push it in?
