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.
Beneath the superior Diamond Like finish resides all the quality and attention to detail and materials that Toolcraft is famous for.
Toolcraft uses a type of 8620 steel in their carriers that is not used by anyone else in the industry. It's a proprietary blend of steel that is superior to the 8620 steel used by other manufacturers.
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.
Our Toolcraft DLC Bolt Carrier Groups are paired with MIL-SPEC Carpenter 158 bolts. 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 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.
