Description
This product group features an AR-15 Nickel Boron Bolt Carrier Group ( 5.56/.223/300AAC ) combined with an ambidextrous charging handle. The bolt carrier group (BCG) is without a doubt the hardest working component inside an AR15. It is responsible for guiding the firing pin to the primer, extracting and ejecting the fired case, feeding the new cartridge into the chamber, and locking properly into the barrel extension. All of these tasks require an uncompromising need for minimal friction. This Nickel Boron BCG has an advanced metal finish that offers high resistance to wear and corrosion as well as having an ultra-low co-efficient of friction, resulting in smoother cycling and less required lubrication. Due to this technologically advanced surface finish, clean up is easier and faster than with standard bolt carrier groups.

Nickel Boron Bolt Carrier Group
This Bolt Carrier Group (BCG) comes fully assembled and ready to drop into most mil-spec M16, M4, & AR15 upper receivers. All critical parts are coated with Nickel Boron that provides permanent dry lubricity, extreme durability and increases both wear and corrosion resistance. The Nickel Boron coating has a Rockwell hardness between 52-56. This bolt carrier group is constructed from 9310 Vac-Arc steel making it far superior than BCG’s constructed with the standard Carpenter 158 spec.
Ambidextrous Charging Handle (CHH)
A central component of your AR-15, the charging handle not only assists in chambering a round but is your main tool to clear a round that won?t eject cleanly. The 7075-T6 aluminum design results in a rugged and capable charging handle for your AR-15. Large textured unlocking latches on either side allow you to conveniently and quickly charge your AR15. The latches are designed so that you can use the palm of your hand or your thumb for quick weapon manipulations.

The BCG is awesome. But I’ve tried 2 different instances of the ambidextrous charging handle, and neither seem to be in spec to slide freely in my upper. CBC was very gracious in swapping them out, but I think these are just manufactured incorrectly. I’ll just keep the BCG and continue using my old charging handle.
