Range Rods are caliber specific, and available for all bore sizes. They are made of steel, 6" (~152mm) long.
Bushing is sized to standard for the caliber chosen. Other sizes are additional charge please see this link - > Reamer / Barrel Tool Bushings
Like our Premium Chamber Reamers, our Range Rods use removable pilot bushings to perfectly center the tool tip in the bore. Each Range Rod features a tapered section, 3.5" (~89mm) long, so the rod will self-center when fully inserted. The protruding section of the Range Rod provides a precise reference, to establish alignment and center for machining operations on the barrel. Range Rods are typically used with unchambered barrels, prior to chamber reaming.
Note: To assure perfect concentricity and repeatability, apply the best-fitting bushing on a 60 degree center reamer, and very carefully cull .008" (0.2mm) of material from the bore. This will ensure a smooth, flawless edge for the Range Rod to center on.
