Dial Caliper Body for your Modular Headspace Comparator assembly. Now available with 2 mounting configurations: “Centered” for normal use, “Offset” for use with Hornady COAL Tools. ***Body is required to use Bullet and Headspace Inserts*** This is the body only for the Modular Headspace Comparator tool. You must purchase the body for the Modular Headspace Comparator inserts to work. Available in two configurations. Standard: The longest of the two configurations, works with loaded ammunition up to 338 Lapua Magnum with solid turned bullets. Short: The shortest body of the two configurations. More compact when the customer wants to dedicate a body for measuring fired brass or bullets only. Made from 6061 Aluminum made in the U.S.A. these bodies clamp onto your dial calibers allowing the Headspace and Bullet inserts to be changed quickly with the use of any tools. Both Standard and Short Modular Headspace Comparator Bodies have two clamping configurations when mounting to your dial calipers. Configuration “C”: Centered With the 10/32 Thumb Screw mounted on the bottom side with a “C” means that the Modular Headspace Comparator Body will be centered on the dial calipers. This is standard for all normal uses. Configuration “O”: Offset With the 10/32 Thumb Screw mounted on the bottom side with a “O” means that the Modular Headspace Comparator Body will be offset on the dial calipers. When using the Hornady COAL measuring tools, the Modular Headspace Comparator body must be offset on the dial calipers in order for the Hornady tool to be properly aligned with the Modular Headspace Comparator assembly.
