How can FailZero parts operate with no lubrication?
FailZero parts are treated with EXO Technology, a patented process deposits a nickel boron casting 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 fewer intervals then standard wet-lube parts. There is no lube to attract and hold grit, create crud and gunk, or thicken up. Fouling can be brushed away with a steel brush with little effort. A normal cleaning schedule is suggested even with FailZero but alcohol wipes should be all thats necessary. Do NOT use cleaning solvents that react negatively with Nickel.

What firearms will FailZero parts fit?
Currently two FailZero upgrade kits are available: semi-auto and full-auto bolt/carrier groups for AR-15/M4 tactical rifles . All FailZero parts are mil-spec quality, so they will correctly fit AR/M4 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 by tactical 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.
