Mass production of a greatly improved infrared night vision system began in 1950 with the “20,000 volt Set No. 1”. This could be mounted on any M1 or M2 carbine, making it a “M3 Carbine.”  About 20,000 of these scope sets were made in 1950-1951, and they were used during the Korean War and remained in inventory until the mid-1960s. 6park.com
