EXO Bolt/Carrier Groups - Simply the best!

Upgrade your AR15 and M16/4 rifles with FailZero EXO technology parts, and you eradicate failures caused by wet-lubrication: worn-off lube, gun-jamming gunk, dry gritty parts. Nickel Boron coated parts never need grease or oil, eliminate gunk and crud, and dramatically reduce downtime.  EXO ensures optimum performance for your weapon under rugged real-world conditions. That's good to know when the pressure is on.

All FailZero parts are mil-spec quality and will properly fit AR/M4 rifles.  Coated parts have been tested in BushMaster, Rock River Arms, Springfield Armory, DPMS, Double Star, Stag Arms, Colt, Kimber and other platforms.

If you are a law enforcement professional, serious shooting enthusiast, firearms refurbisher or gunsmith, you can count on FailZero upgrades to deliver a serious advantage.
