This review details the failure of the Osight XR red dot sight after 11,000 rounds, primarily due to overheating during high-volume shooting in warm conditions. The optic displayed slow response times and eventually shut off, displaying an undocumented seven-blink red light error code before becoming completely unresponsive. The reviewer highlights the optic's limited operating temperature range (32-113°F) as a critical design flaw for duty or high-volume training applications, contrasting it with more robust optics like the Aimpoint T2.
