Mark 7 Reloading Optical DecapSense Sensor for 650

The Mark 7 Reloading Optical DecapSense Sensor for 650 is a precision quality-control accessory designed to eliminate primer decapping failures on the Mark 7 650 Autodrive reloading press. This optical sensor detects whether a spent primer has been successfully removed from the case during the decapping station, preventing the catastrophic scenario of a live primer being seated over a failed decap—a condition that renders ammunition unsafe and unshootable.

Reloading operators working high-volume production runs face a critical blind spot: a broken decapping pin or a stubborn spent primer that doesn't fully eject can go undetected until downstream in the swage station, where it gets pushed back into the case. The DecapSense uses optical recognition technology to verify primer removal in real time, stopping the press cycle and alerting the operator before a defective round moves to the next stage. This sensor integrates seamlessly into the 650 Autodrive's automation sequence, adding a layer of quality assurance that manual visual inspection cannot reliably provide during rapid-fire production.

The sensor is essential for serious handloaders, ammunition manufacturers, and high-volume reloading operations where consistency and safety are non-negotiable. Whether you're processing large batches for personal use or small-scale commercial production, the optical DecapSense eliminates the guesswork and reduces scrap rates caused by incomplete decapping. Weighing 0.66 lbs and designed for direct integration with the Mark 7 650 platform, this accessory represents the difference between reliable ammunition and potentially dangerous cartridges that can damage firearms or cause injury.
