Dirty or bad pot on iris control UMP G1

PostThu Feb 01, 2024 1:34 am

The little adjustment wheel for iris makes the aperture jump around moving up and down sporadically. I’m afraid to spray tuner cleaner in it as close as it is to the sensor and optics. Not end of the world stuff but shoulder mounted I anticipate problems. Maybe I’ll try spraying it with compressed air?
