Operation

edit

The AK53 used the gas-operated principle of operation with the barrel moving forward to operate the cycle. Because a piston is used to move the barrel, this action does not fall under the blow-forward concept. The AK53 was developed during the late 1940s and early 1950s but was rejected. However, it did lead to the SIG SG 510 battle rifle, which was in use for over thirty years.
