FailZero M16/M4 Bolt Carrier Group, EXO Nickel Boron Coated, Matte Finish

From the Founder:

FailZero is a great bang for the buck, and adds some peace of mind for your next build. Their coatings are slick and easy to clean, and the brand has shown itself to be consistent and reliable. I use them on my personal guns and have been quite happy. You can easily spend more on a BCG, but it’s hard to say if what you are getting is actually any better.

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 permanent dry lubricity, extreme durability and increases both wear and corrosion resistance.

Ships in Retail Packaging.

Features:

• Nickel Boron treated
• Extreme durability
