Mark 7 PrimerSense

Enhances the compatibility of your Dillon Low Primer Alarm with the Mark 7 Autodrive, ensuring that it effectively halts the reloading process when your primer supply is running low.

The PrimerSense® Low Primer sensor eliminates any guesswork in your reloading setup by providing a mechanical alert when your primer levels are insufficient. The Mark 7® unit already features a programmable stop function for low primers, which can be activated through the included tablet. When your low primer alarm is triggered, it will also bring the Autodrive to a stop. By installing this mechanical unit, you benefit from a dual layer of protection against both primer shortages and the potential mess of spilled powder on your shell plate
