A completely assembled, ready to install AR-15 Bolt Carrier Group. Kit includes six critical parts that are treated with EXO Technology, a revolutionary surface technology that provides permanent dry lubricity, radically improves the performance of your AR-15 and eliminates the need to apply oil or grease to treated parts for the life of the weapon. All Fail Zero bolts are MPI tested and live fire tested. They do not do HPT, as they feel live fire is a better test.
