FailZero M16/M4 Bolt Carrier Group W/O Hammer - Black Finish

FailZero

This BCG is perfect for shooters looking for a tactical advantage resulting from the non-reflective properties.

The carrier comes with a black topcoat/exterior with FailZero EXO Nickel Boron underneath. We've introduced this carrier to provide non-reflective properties, resulting in a Tactical Advantage. However, PLEASE NOTE that wear areas including ramps, rails, and other contact points such as carrier ends will wear - exposing the Nickel Boron coating beneath.  The critical non-wear areas which are exposed during operation, i.e. the dust cover area will remain black. Typically non-wear areas on outside of the carrier will retain the black overcoat.

This Bolt Carrier Group (BCG) comes fully assembled and ready to drop into most mil spec M16, M4 or AR15 upper receivers.  All critical parts are coated with EXO Nickel Boron technology that provides permanents dry lubricity, extreme durability, increase wear and corrosion resistance.  Our patented Nickel Boron coating will reduce friction and improve the overall performance of your rifle.

Nickel Boron treated parts include:

  • Bolt & Extractor (5.56/.223 compatible)
  • Bolt Carrier
  • Extractor
