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 is 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 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.
