In the year 1959 the AK47 was modified and was consequently adopted (after trials) as the AKM (Avtomat Kalashnikova Modernizirovannyj - Kalashnikov Automatic rifle, Modified). The key changes were the introduction of the stamped receiver instead of the milled one, and improved trigger/hammer unit, that introduced a hammer release delay device (often incorrectly referred as a rate reducer). Other changes were the redesigned, slightly raised buttstock and the pistol grip, and the addition of the removable muzzle flip compensator. This spoon-like compensator is screwed onto the muzzle and used the muzzle blast to reduce muzzle climb during the burst fire. The compensator could be replaced by the screw-on "PBS-1 noiseless firing device", generally known as a silencer. Another change from AK to AKM was a slightly improved rear sight, with settings from 100 to 1000 (instead of the 800 on AK) meters. Both 800 and 1000 meters, however, are way too optimistic for any practical use, since the effective fire is limited roughly to 300-400 meters, if not less.

AKM with silencer
  In 1974 the Soviet Army officially adopted the 5.45mm ammunition and the appropriately chambered AK74 assault rifle as its new standard shoulder arm. The AKM, however, was never officially removed from service, and is still in Russian army stocks. many non-infantry units of the Russian Army are still armed with 1960s vintage AKM assault rifles. There's also an increasing interest in the 7.62mm weapons since many troops were disappointed by the effectiveness of the 5.45mm ammo during the local conflicts in the 1990s. Soldier reported that although an enemy was hit he still was able to fight. Some Russian special forces troops (mostly police and Internal Affairs Ministry) are using the venerable 7.62mm AKM rifles.
