FAILZERO tactical upgrades give law enforcement, security and military professionals the "active weapon advantage" in critical use: no grease to hold grit, no oil to wear off, no gun-jamming crud on key components. FAILZERO tactical rifle upgrades and pistol drop-in kits use patented EXO Technology to provide permanent dry lubricity to metal surfaces. This breakthrough technology, thoroughly proven in SWAT applications, DOD testing and battlefield conditions, creates a greaseless, permanently lubricious surface that's harder than the substrate itself. Unlike films, conventional coatings and applied lubricants, it never rubs off, thins out, spalls off or builds up crud. FAILZERO upgrade parts reduce maintenance and improve the performance of tactical firearms.
