The FailZero AR-15 Semi-Auto Bolt Carrier Group (BCG) (no hammer) comes fully assembled and ready to drop into most mil spec M16, M4 or AR15 upper receivers. All of the critical parts are coated with FailZero's EXO Nickel Boron which provides permanent dry lubricity, extreme durability, corrosion resistance and will reduce friction and improve the overall performance of your AR-15 based rifle.

Wet lubrication is never needed. The EXO Technology dissipates heat so efficiently that the rifle will run cooler and cleaner since wet lubrication isn't needed.

All FailZero parts are mil-spec quality.

Nickel Boron treated parts include:
  • Bolt & Extractor (5.56/.223 compatible)
  • Bolt Carrier
  • Extractor
  • Cam Pin
  • Carrier Key
  • Firing Pin

Absolutely the best BCG for the money!
Absolutely the best BCG for the money. I run several of these now, and love them. They ooze quality. Super easy to clean, carbon wipes right of. Of the three that I've installed, head space was dead on.
