5.45x39mm Ammo

5.45x39mm Ammo For Sale- Top Ammo Retailers Available

The 5.45×39mm cartridge is a rimless bottlenecked intermediate cartridge. It was introduced into service in 1974 by the Soviet Union for use with the new AK-74.

The 5.45×39mm gradually supplemented, then largely replaced the 7.62×39mm cartridge in Soviet and Warsaw Pact service as their primary military service rifle cartridge. 5.45x39 is popular today, both in the United States and across the world.

The 5.45×39mm cartridge was developed in the early 1970s by a group of Soviet designers and engineers under the direction of M. Sabelnikov. The 5.45×39mm is an example of an international tendency towards relatively small-sized, lightweight, high-velocity military service cartridges.
