This 6mm barrel blank is intended for shooters building a custom rifle around a 29-inch light varmint profile and a 1-13.5" twist rate. It is a Bartlein product made with single point cut rifling, with pre-lapping and honing before rifling and finish lapping afterward. The listed 243/6mm land and groove diameter is .237/.243, and it may require a live pilot with the appropriate sized pilot, as a solid pilot may not fit. Best suited to a serious custom build where barrel selection and chambering details are being matched carefully.
