I have 720 rounds of 5.56 tracer for sale for $100. Purchased it on a whim and decided I don't want it afterall. Boxes are marked Olin Mathieson Chemical Company Lot WCC 6164. Supposedly Lake City. Reviews on it are mixed. Some people are saying that it is great, others are reporting that there are primer issues. Can be picked up in Washington NJ 07882. Call my cell at 908-246-4735 Joel
