Based on the Romanian variant of the Russian RPK (the Puşcă Mitralieră model 1964), the AES 10B is a semiautomatic rifle chambered in 7.62x39mm. Regarded as the "big brother" to the standard AK, these rifles are truly robust and durable. These rifles are newly produced in Romania and available in a limited quantity. The AES 10B rifles are true to the original design, with a heavy barrel which will hold accuracy over sustained periods of fire, an RPK-style adjustable bipod, and an RPK-style clubfoot stock.
