The Area 419 Headspace and Ogive Gauge Height Stand is a nice addition to the full body and base kit, sold separately. When building this kit, Area 419 wanted you to have the option to use it like a tool you probably use every day in the shop - a height gauge. This heavy steel base, with rubber bottom, will keep your measuring tool in place, clicking the tool in with magnets, and add to the flow of your reloading QC process. Note: This base is a separate item, and is not included in the kit
