300 BLK

This is fully processed and ready to load 300 AAC Blackout brass that's made from once-fired military brass.  Due to the nature of processing 300 BLK brass from the 5.56/223 parent case, we only offer this brass in the fully processed configuration.  If you wish to make your own 300 BLK from unprocessed or partially processed cases, we encourage you to view our category containing 5.56/223 brass.  We also want to stress that this brass is guaranteed to have only been fired once in the entirety of its lifetime - we don't sell any range pickup brass or brass from sources where we can't verify the number of times it's been fired.
