2-cm FlaK 381
Mauser was given the task to improve on the 2-cm FlaK 30, which had a tendency to jam, and had a low rate of fire.1
The 2-cm Flak 38 appeared in 1940 and had an improved breech allowed for 420-480 rpm.1
The sight was a Flakvisier 38, which was fragile, complex, and expensive.1 This was replaced in 1941 by the Linealvisier 38 open ring sight.1 In 1944 this was replaced by the Schwebekreisvisier 38.1
