Description
FailZero is the undisputed pioneer of Nickel Boron technology. When failure is not an option, you can depend on Fail Zero.
This Fail Zero BCG is fully assembled and drop-in ready for most Mil-Spec upper receivers. All critical parts are coated with EXO Nickel Boron technology providing permanent dry lubricity, extreme durability and increased wear and corrosion resistance. This patented Nickel Boron coating will reduce friction and improve the overall performance of your rifle.
Nickel Boron is an extremely durable finish with self-lubricating properties so your AR15 cycles smoother and requires less lubrication. Fail Zero BCGs are plated by UCT Coatings of Palm City FL, the same company that does it for Toolcraft.
Called EXO Technology, this is a patented process that applies a Nickel Boron finish so durable that it is specified on Army 81mm and 60mm mortar tubes, Blackhawk helicopter hoists, and for hard use applications on some Navy ships! IMO, this may be the ultimate upgrade to the All-American AR-15. And it looks good too!
