Decent ar sight. - OpticsPlanet Exclusive Sightmark 1x Mini Shot A-Spec Reflex Sight

Had gotten the sight originally for my g3c optic ready slide, did not work out. Got it installed on my slide, laser bore sighted it, took to range and ran a few shots thru it. Then I would notice it would shut off constantly, so I replaced the battery having a spare in my range bag, ran more rounds thru it and kept shutting off... not sure what issue is maybe couldn't handle the recoil of the g3c. Sight works mounted on AR pistol and works, stays on and doesn't shut off on ARs or shotguns also tried on my mossberg and worked. Maybe slide cycling of g3c was too much..
