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.
Even a great finish like DLC is only the last step in the manufacturing process and there is a lot that goes into every Toolcraft BCG prior to the finish.
To start with, Toolcraft uses a type of 8620 steel in their carriers that is not used by anyone else in the industry.
Beyond the carrier steel, 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.
Above: A smooth finish, free of machine marks is the end result.
This DLC BCG has been paired with a MIL-SPEC Carpenter 158 bolt. This bolt steel has served the U.S. Military well for many decades and when paired with Toolcraft quality and the Ionbond DLC finish, this may be 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.
