Toolcraft Gray BCG 556

Free Shipping on all Toolcraft Bolt Carrier Groups! 

Other colors: Toolcraft DLC Black BCG, and Toolcraft FDE BCG. 

The Ionbond Diamond Like Carbon (DLC) finish is an incredibly hard (90 Rockwell) self-lubricating finish. This makes it extremely resistant to wear and corrosion.  This also makes it an ideal finish for a critical part like an AR15 bolt carrier group.

Toolcraft uses state-of-the-art machinery, processes and quality control to ensure that every bolt carrier group is capable of the most demanding missions. This has made Toolcraft a first choice of OEMs and the U.S. Military.

This Toolcraft DLC Bolt Carrier Group comes complete with a 9310 grade tool steel bolt. This bolt steel is 7% stronger than commonly used MILSPEC Carpenter 158 steel. This tougher than MILSPEC bolt, when paired with Toolcraft quality and the Ionbond DLC finish is quite likely the ultimate hard use bolt carrier group!

This is a 223/5.56/300 Blackout bolt carrier group.

This BCG will not work with 6.5/6.8/308 etc.

Toolcraft products carry a Lifetime Warranty.
