The FailZero M16 Full 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

Excellent BCG
I've had one of these BCG's in one of my AR's for a few years now. Very easy to clean. I still put lube on it even though they say it doesn't need it. I've had zero problems with it.
