Overview

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.

Pros

  • Single-point cut rifling only, with no button rifling or broach cutting.
  • Prelapped and honed before rifling, then finish lapped after rifling.
  • Bartlein states its machines hold uniform twist rates to the 4th decimal point.
  • 6mm barrel blank with 1-13.5" twist and 29" light varmint profile.
  • May accept a live pilot with appropriately sized pilot for fitting.

Considerations & Trade-offs

  • May require a live pilot with the correct pilot size; a solid pilot may not fit, so compatibility needs to be checked before ordering.
  • This is a barrel blank, so it is intended for a separate gunsmithing or fitting process rather than a ready-to-install component.
  • The product is offered in a specific 6mm configuration with a 1-13.5" twist and 29" light varmint profile, so it is not a flexible all-purpose option.
  • The provided specifications focus on land/groove diameters and rifling method, but do not include other fitment details that may matter for a build.
