How can FailZero parts operate with no lubrication?FailZero parts are treated with EXO Technology, a patented process that transforms a metal surface into a permanently dry-lubricious material that’s harder than the substrate itself. It’s dry-lubricious properties reduce friction so well, no wet lubrication is ever needed. And, EXO Technology dissipates heat so efficiently, operating parts run cleaner and cooler – a great benefit in semi-automatic and automatic weapons.

Do FailZero parts ever need cleaning?FailZero parts do require cleaning, but at far less intervals then standard wet-lube parts. There is no lube to attract and hold grit, create crud and gunk, or thicken up. FailZero parts will operate until too dirty to function. Fouling can be brushed away with a steel brush with little effort. A normal cleaning schedule is suggested even with FailZero.

What firearms will FailZero parts fit?Currently three FailZero upgrade kits are available: basic and full auto kits for AR-15/M4 tactical rifles, and a drop-in kit for 1911 pistols. All FailZero parts are mil-spec quality, so they will correctly fit AR/M4 and 1911 firearms.

Have FailZero parts been proven in real-world use?FailZero parts have been thoroughly tested by the U.S. Department of Defense, by law enforcement departments nationwide, by rigorous internal testing, and bytactical training centers. Much of the test data is proprietary under military secrecy provisions. FailZero parts are currently in use by SWAT teams, security agencies, and by military troops under battlefield conditions. Other EXO treated parts are used in military advanced weapons systems, mortar tubes and components, missile testing systems, and more. And, FailZero parts are guaranteed for life.

What are FailZero’s warranty and return policies?FailZero parts are guaranteed for life. You can return any FailZero part, for any reason, with 30 days.

9/09 Chris Costa now at 11,800 rounds with EXO coated BCG (He does lightly lube the gas rings on his bolt).
EXO coated Knight’s Armament BCG with 3500 rounds unlubricated used by Chris Costa in Vickers Tactical class shootout.
Vickers Tactical put on an invite only class for M4C and invited guests the weekend of March 14, 2009. Chris Costa of Magpul Dynamics walked away with top honors in the match after performing extremely well on the shooting stages. Chris shot very well throughout the class and managed to claim top spot in a lot of drills. Chris was using a Knight’s Armament bolt carrier group coated with EXO technology. He has over 3500 rounds on this BCG and has not lubricated it. Just clean and go. Congratulations Chris, on the great shooting. Keep us informed as you continue with your test firing.
