The BCB 6MM ARC Barrels were created to fill a gap in the newly emerging 6ARC market. The current options available, outside of custom made barrels, tend to be both heavy and heavily gassed. The BCB 6ARC barrels were made with precision in mind to match the potential of the 6ARC cartridge while having a much lighter profile than other commercially available alternatives.  Much of the feedback on current offerings in 6ARC, has been a tendency to be over gassed. Our goal was to offer a barrel focused on optimal performance out of a suppressed platform.
