Chicom Type 56 7.62mm Rifles (AK-47)
The Chinese Type 56 rifle is none other than the famous Russian Avtomat Kalashnikova 47 or AK-47. Designed by Mikal T. Kalashnikov and first adopted by the USSR in 1947, over 70 million AKs have been produced throughout the world. It is still in production today.
The Type 56 is a third model AK. That is, it uses a milled steel receiver. Originally a 6 pound block of forged steel, after much machining a 2.75 pound finished receiver emerges. The Russians found this to be a rather wasteful way to make AKs even for them, and so production of the third modelin the USSR only lasted from 1954 through 1959. The AK-47 was superseded in production by the AKM (or moderized AK) in 1960. The AKM uses a stamped receiver with the rear trunnion (which holds the butt stock) and the forward trunnion (which holds the barrel assembly and rear sight) both riveted to the stamping.
Production of the Type 56 began in 1958. The Type 56 may be found in either the standard AK-47 pattern with detachable blade bayonet, a folding stock variant with detachable blade bayonet, a standard AK-47 pattern with folding spike bayonet, and a folding stock variant with folding spike bayonet. The hinese also produced the rifle in an export version. This rifle carried the designation "M22." During the Viet Nam war, the Type 56/M22 became the most common of the AKs encountered by American units. Like is Russian AK-47 counterpart, the Type 56 made the transition from a milled receiver to a stamped receiver. Type 56 rifles in production today are equivalents to the Russian AKM.
The rifle is about 35 inches long, weighs about 10.5 pounds loaded, and shoots the intermediate-sized 7.62x39mm cartridge. It is capable of both full-automatic and semi-automatic fire. The Cyclic rate is 550 to 650 rounds/minute. Russian tactical doctrine specifies that this rifle's settings are SAFE, FULL AUTO, and SEMI AUTO (in that order). These settings are just the reverse of NATO settings which put FULL AUTO last.
The rifle is very simple to operate and very robust under all conditions. The chrome lined chamber, bore, and gas piston assure the AK's operation with even the most corrosive of ammunition. The rifle was designed to survive in the field with no maintenance. All that was required was that it the dirt was brushed off and the rifle was ready to fire. The rifle is not as accurate as the M-16. However, the AK is accurate enough for what it is designed to do within the 200 to 400 yard envelope for infantry combat.
