The EXO NiB breakthrough technology creates a permanently lubricious surface, harder than the substrate itself, which eliminates the need for grease, oil, or any wet lubrication for the life of the weapon. Unlike films, conventional coatings and applied lubricants, it will never rub off, never flake off, never build up crud. EXO Technology eliminates wet-lubrication failures of critical components, giving you an "active weapon advantage" under all conditions.Note: Upon installation, headspace should be verified by a qualified gunsmith.Features308 Winchester Bolt FaceMachined to Mil-Spec StandardsProperly Staked Gas K...
