The AKM’s receiver, compared to the AK-47, has a stamped sheet metal housing to which a rear stock trunnion and forward barrel trunnion are fastened using rivets. The receiver housing also features a rigid tubular cross-section support that adds structural strength. Guide rails that assist the bolt carrier’s movement which also includes the ejector are installed inside the receiver through spot welding.
The forward barrel trunnion has a non-threaded socket where the barrel is embedded and a hole for a pin that secures the barrel in place. On some models the rear trunnion has two extended mounting arms on both sides that support the buttstock, other fixed models use a stepped shaped trunnion that covers the full width of the inside of the receiver.
The stamped dust cover contains both longitudinal and latitudinal reinforcing ribs for increased durability and decrease weight because of the use of thinner sheet metal
The AKM’s barrel is installed in the forward trunnion and pinned (as opposed to the AK-47, which has a one piece receiver with trunnions that are not removable and a barrel that is screwed-in). Additionally the barrel has horizontal guide slots that help align and secure the handguards in place. To increase the weapon’s accuracy during rapid fire, the AKM was fitted with a slant cut muzzle brake that helps redirect expanding propellant gases upward and to the right during firing. The muzzle brake is threaded on to the end of the barrel. The AKM's slant brake can also be used on the AK-47.
The AKM also has a modified trigger assembly, equipped with a hammer-release delaying device (installed on the same axis pin together with the trigger and disconnector). This device reduces "trigger slap" or "trigger bounce" and the weapon’s rate of fire, which also reduces the dispersion of bullets when firing in fully-automatic mode. The hammer was also changed and equipped with a protrusion that engages the rate reducer and the trigger has only one notched hammer release arm (compared to two parallel arms in the AK-47).
A Moroccan soldier trains with a PM md. 63 alongside U.S. Marines.
The gas block in the AKM does not have a cleaning rod capture or sling loop but is instead fitted with an integrated bayonet support collar that has a cleaning rod guide hole. The forward sling loop was relocated to the front handguard retainer cap, the handguard retainer also has notches that determine the position of the handguards on the barrel. The AKM’s laminated wood handguards have lateral grooves that help securely grip the rifle.
Gas relief ports that alleviate gas pressure in the piston cylinder (placed horizontally in a row on the gas cylinder in the AK-47) were moved forward to the gas block and placed in a radial arrangement.
The AKM’s bolt carrier is slightly lighter in weight and despite some minor differences in its shape – it can be used interchangeably with the AK-47’s bolt carrier and bolt.
The wooden stock used in the AKM is further hollowed in order to reduce weight and is different in shape to a small degree.
The AKM uses a modified return spring mechanism, which replaces the single recoil spring guide rod with a dual “U”-shaped wire guide.
The AKM’s rear sight consists of a ramp with a range scale marked from 100 to 1,000 m (graduated every 100m), as compared to that of the original AK-47, which was graduated to 800meters. The rear sight leaf’s position teeth that secure the sliding adjustable notch were transferred over from the right to the left edge of the ramp. The front sight post also has a slightly different shape and its bottom portion is more narrow.
The AKM comes supplied with a different accessory kit that contains a M1959 6H4 or 6H3-type bayonet (that forms a wire-cutting device when coupled with its scabbard) and comes with synthetic or alloy magazines. The kit also comes with a punch used to drive out various pins and a device that aids in assembling the rate retarding mechanism.
The AKM uses the same ammunition as the AK-47: the 7.62x39mm M43 intermediate rifle cartridge. The arrangement of mechanisms and parts in the AKM and their interaction during loading and firing is practically identical to AK-47, the only difference being the trigger assembly (during the return stage of the bolt carrier on fully automatic mode) as a result of incorporating the rate reducer device.
