The Mark 7 Bullet Sense Detection Sensor (Mark 7 Reloading part no. 101-1082) is an electronic detection system built for the Mark 7 1050 and RL1100 progressive reloading presses, designed to stop the machine before a missing bullet, a toppled bullet, or an empty case gets fed into a finished round. It works by mounting a laser on a user-adjustable slider, aimed precisely at the bullet tip or the case mouth; if the beam is interrupted on every stroke, the press continues, and if the beam reflects back uninterrupted, the press stops at the top of the stroke. It can also double as a brass-presence sensor, giving reloaders a second layer of protection against costly mistakes on a high-volume press. We stock more from Mark 7 Reloading as well.
