The AO-36 was a prototype twin-barrel assault rifle of Soviet origin, developed in the 1960s.
Development[edit | edit source]
The AO-36 was designed at TsNII TochMash in 1965 by Sergei Simonov and Peter Tkachev. The twin-barrel design was intended to produce a higher hit probability when the rifle was fired from a standing position. However, the AO-36 proved heavy, difficult to field strip and much more expensive to produce than the AKM. Only a single prototype was produced.
Overview[edit | edit source]
The AO-36 was a twin barrel, gas operated select-fire rifle chambered for an experimental 5.6mm round, the 13MZH (13МЖВ), which was derived from the 7.62×39mm cartridge. The weapon fired both barrels simultaneously: the operation uses one gas piston with a gas block tapped from both barrels, acting on one bolt group using a tilting bolt. The AO-36 is fed from a single box magazine, internally divided into two double-column feeds: the capacity of this magazine is not clear.
