Russian AN-94 self-loading rifle | The Hoplite
The Nikonov rifle features a variable rate of fire, with a two-round burst mode operating at 1800 rpm, and a conventional automatic mode at 600 rpm. To achieve this, a combined gas and recoil-operated system was coupled with a unique feed system. Simply put, two cycles of the gas system are completed for every one of the recoil system. Thus two rounds are fired before the recoiling firing unit strikes the rear buffer, although only a few millimetres before, as the high speed footage reveals.
