The AKM is a gas operated, selective fire assault rifle. Gas, selective fire 30-round detachable box magazine 869 mm 4 grooves, rh, 1 turn in 235 mm 710 m/s 400 m Technical description for the AKM assault rifle: 3įore, post, adjustable rear, U- Muzzle notch, tangent velocity: Effective cyclic, 600 rds/min range: Both 8 meters, however, are excessively optimistic for any practical use, since the effective fire is limited roughly to 300-400 meters, if not less. 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. This silencer required special, sub-sonic ammunition with heavier bullets to be used. The compensator could be replaced by the screw-on "PBS-1 noiseless firing device", generally known as a silencer. This spoon-like compensator is screwed onto the muzzle and used the muzzle blast to reduce muzzle climb during the burst fire. Other changes were the redesigned, slightly raised buttstock and the pistol grip, and the addition of the removable muzzle flip compensator. 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). By the 1959 the AK was modified again, this time more extensively, and was consequently adopted (after trials) as the AKM (Avtomat Kalashnikova Modernizirovannyj - Kalashnikov Automatic rifle, Modified). The total number of the AK-type rifles made worldwide during the last 50 years is estimated at 90+ millions. It had been and still is (in more or less modified forms) manufactured in dozens of countries, and used in hundreds of countries and conflicts since its introduction. The Kalashnikov assault rifle, also known as the AK-47 (Avtomat Kalashnikova - 47, Kalashnikov automatic rifle, model of 1947), and its derivatives, also known under the common name of AK, is the most prolific small arm of the 2nd half of the XX century. The folding-stock model can reduce its length from 868 to 699 millimeters. Except for its Tshaped, stamped-metal, folding butt stock, the AKMS is identical to the AKM. The AKM also has a folding-stock version, designated AKMS, intended for use by riflemen in armored infantry combat vehicles such as the BMP. Other improvements include a straighter stock for better control an improved gas cylinder a rate-of-fire control alongside the trigger a rear sight graduated to 1,000 meters rather than 800 meters and a greatly improved, detachable bayonet. The reduced weight results from using thinner, stamped sheet metal parts rather than machined, forged steel laminated wood rather than solid wood in the hand guard, forearm, pistol grip, and butt stock and new lightweight aluminum and plastic magazines. It weighs about one kilogram less than the AK. The improved model, known as the AKM, is easier to produce and operate. The early AKs had no bayonet, but the version with the fixed wooden stock later mounted a detachable knife bayonet. Except for the differences in the stock and the lack of a tool kit with the AKS, the two version were identical. The AK came in two versions: one with a fixed wooden stock, and another, the AKS, with a folding metal stock issued primarily to parachutist and armor troops. Like all 7.62-mm Kalashnikov assault rifles, it fired the Soviet 7.62 x 39mm M1943 round and used a standard 30-round curved box magazine. It was a gas-operated, selectivefire weapon. The original AK was also known as the AK-47. Note that the stamped receiver has small indents above the magazine instead of the machined cuts on the earlier AK models.ĪKM with GP-25 40mm under barrel grenade launcher Note the distinctive machined cuts above and forward of the magazine well.Īutomat Kalashnikova Modernized - AKM assault rifle, with the multipurpose bayonet-knife.
