• 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. 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 total number of the AK-type rifles made worldwide during the last 50 years is estimated at 90+ millions. This is a true legendary weapon, known for its extreme ruggedness, simplicity of operation and maintenance, and unsurpassed reliability even in worst conditions possible. It is used not only as a military weapon, but also as a platform for numerous sporting civilian rifles and shotguns (see Saiga semiautomatic shotguns, for example). The AK is an amalgam of previously known features and solutions, combined in the most effective way. The effectiveness, however, depends on the criteria used to measure it, and the key criteria for any and every Soviet and Russian military arm are: Reliability, Simplicity of operation and maintenance, Suitability for mass production. There never was any significant demand for good ergonomics or superb accuracy, though. In general, the AK can be described as an ideal small arm for the past war (the Second World War). Obviously, it's not a surprise - AK incorporated most lessons learned the hard way during that war.
• The official story of the AK says that the sergeant Mikhail Kalashnikov, being in hospital after the wound, began to develop various small arms during the World War 2. Circa 1944 he was assigned to the Izhevsk Machinebuilding Plant (IZHMASH), where in 1944 he developed a semi-automatic, gas-operated carbine. Starting with this design, during 1945 and 1946 he developed an assault rifle that he submitted for official Soviet Army trials in 1946. During the 1946 and early 1947 he redesigned his initial rifle and submitted it to the second trials, held in 1947. The latter design was found superior to the rivals and was consequently adopted in 1949 as the "7,62mm Automat Kalashnikova, obraztsa 1947 goda" (7.62mm Kalashnikov automatic rifle, model of 1947). After extensive field trials it was slightly modified in 1951, but retained the same name. Along with the basic version, a folding butt version had been developed for paratroop forces, and it was named AKS.
• 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 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. This silencer required a special, sub-sonic ammunition with heavier bullets to be used. 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.
• In the 1974, Soviet Army officially adopted the 5.45mm ammunition and the appropriately chambered AK-74 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. Some Russian special forces troops (mostly police and Internal Affairs Ministry), currently operating in Chechnya, are using the venerable 7.62mm AKM rifles.
• The AK and AKM rifles also were widely exported to the pro-Soviet countries and regimes all around the world. Manufacturing licenses along with all necessary technical data packages were transferred to many Warsaw Pact countries (Bulgaria, East Germany, Hungary, Romania, Yugoslavia) and to some other Communist countries, like China and North Korea. Some non-communist, but friendly countries, like the Egypt, Finland and Iraq, also received these licenses. The AK is the only firearm ever that was depicted on the national flag - the Mozambique flag features a distinctive silhouette of the Kalashnikov rifle.
• At the present time almost all manufacturers of the AK-type weapons ceased the production of the 7.62mm assault rifles for the military use (except probably for the newest AK-103, made in limited numbers by the IZHMASH in Russia). On the other hand, production of the semi-automatic only civilian AK derivatives is continued in many countries, including Russia, Bulgaria, Romania, China and some others.
• Technical description for the AKM assault rifle:
• The AKM is a gas operated, selective fire assault rifle.
• The gas operated action has a massive bolt carrier with a permanently attached long stroke gas piston. The gas chamber is located above the barrel. The bolt carrier rides on the two rails, machined in the receiver, with the significant clearances between the moving and stationary parts, which allows the gun to operate even when its interior is severely fouled with sand or mud. The rotating bolt has two massive lugs that lock into the receiver. Bolt is so designed that on the unlocking rotation it also makes a primary extraction movement to the fired case. This results in very positive and reliable extraction even with dirty chamber and cases. The rotation of the bolt is ensured by the curved cam track, machined in the bolt carrier, and by the appropriate stud on the bolt itself. The return spring and a spring guide are located behind the gas piston and are partially hidden in its hollow rear part when bolt is in battery. The return spring base also serves as a receiver cover lock. The cocking handle is permanently attached to the bolt carrier (in fact, it forms a single machined steel unit with carrier), and does reciprocate when gun is fired.
• The receiver of the AKM is made from the stamped sheet steel, with machined steel inserts riveted into the place where required. Earliest AK-47 receivers were also made from the stamped and machined parts, riveted together, but this soon proved to be unsatisfactory, and most of the AK (pre-1959) rifles were made with completely machined receivers. The receiver cover is a stamped sheet metal part, with stamped strengthening ribs found on the AKM covers.
• The relatively simple trigger/hammer mechanism is loosely based on the 1900's period Browning deigns (much like the most other modern assault rifles), and features a hammer with two sears - one main, mounted on the trigger extension, and one for the semi-automatic fire, that intercepts the hammer in the cocking position after the shot is fired and until the trigger is released. Additional auto sear is used to release the hammer in full auto mode. The AKM trigger unit also featured a hammer release delay device, which is served to delay the hammer release in the full auto fire by few microseconds. This does not affects the cyclic rate of fire, but allows the bolt group to settle in the forwardmost position after returning into the battery. The combined safety - fire selector switch of distinctive shape is located on the right side of the receiver. In the "Safe" position (topmost) it locks the bolt group and the trigger, and also served as a dust cover. The middle position is for automatic fire, and the bottom position is for single shots. The safety / fire selector switch is considered by many as the main drawback of the whole AK design, which is not cured in the most of derivatives until now. It is slow, uncomfortable and sometimes stiff to operate (especially when wearing gloves or mittens), and, when actuated, produces a loud and distinctive click. There's no bolt stop device, and the bolt always goes forward when the last shot from the magazine is fired.
• AKM is fed from the 30 rounds, stamped steel magazines of heavy, but robust design. Early AK magazines were of slab-sided design, but the more common AKM magazines featured additional stamped ribs on the sides. Positive magazine catch is located just ahead of the trigger guard and solidly locks the magazine into the place. Insertion and the removal of the magazine requires slight rotation of the magazine around its front top corner, that has a solid locking lug. If available and required, a 40 round box magazines of similar design, or the 75 rounds drums (both from the RPK light machine gun) can be used. Late in production plastic magazines of the distinctive reddish color were introduced.
• AKM rifles were issued with wooden stocks and pistol handles. Late production AKM rifles had a plastic pistol grip instead of wooden one. The wooden buttstock has a steel buttplate with mousetrap cover, that covers the accessory container in the butt. The AK buttstock are more swept-down than the AKM ones. The folding stock version had been developed for the airborne troops and its had an underfolding steel shoulder stock. These modifications of the AK and AKM were designated the AKS and AKMS, respectively. AK were issued with the detachable knife-bayonets, and the AKM introduced a new pattern of the shorter, multipurpose knife-bayonet, which can be used in conjunction with its sheath to form a wire-cutter. All AK and AKM rifles were issued with the canvas carrying slings.
• The sights of the AKM consist of the hooded front post and the U-notch open rear. Sights are graduated from 100 to 1000 (800 on AK) meters, with an additional "fixed" battle setting that can be used for all ranges up to 300 meters.
• AKM rifles also can be fitted with the 40mm GP-25 grenade launchers, that are mounted under the forend and the barrel. Grenade launchers had its own sights on the left side of the unit.

Cyma Cm031 Full Review from Airsoft Forum, member "tyler {332nd} ham"

Cyma Cm031 Full Review,
Lets start off with the body:

Metal parts include:
Muzzle flash
front sight assembly
"cleaning rod"
outer barrel
Outer "Gas tube"
rear sight assembly
upper reciever
selector switch
trigger
trigger guard
mag release
front and rear sling rings

This is a very hefty gun. Very solid also. The body is very detailed. CYMA definatly outdid themselves here. Blows my UTG warhawk out of the water IMO.

The gearbox is a Version 3. Now, I didnt rip this gun apart, since I don't want to have to deal with putting it back together...I usually send my guns in to have work done to them.

This gun comes with the gun, cleaning rod, sling, BBs, mag, 8.4 1200 mAh battery (SMALL size adapter fyi...), charger, and manual.


When I opened the box up, I put the battery on the charger for the amount of time it takes for a full charge (4 hours, 25 minutes) and went out back. This gun shoots about 325-345fps stock, and the ROF is between 750-825. Stick an 8.4 3300 mAh, and watch all that go up. I blew an unopened can of coke in half on full auto...pretty cool.

Accuracy is very good for a CYMA, somewhat better than a warhawk, but wont beat a CA or ICS by any means. Then again, I'm shooting 2nd rate BBs, so that probably has something to do with it. From about 75 feet I got nice 6x6 inch groupings on full auto.

The stock mag is ABS plastic, and is nothing special. However, it destroys the UTG mags in quality. Its just a typical 350-400 round ABS plastic mag. Wind it every 100 shots or so. However, it has the flip up cover instead of that stupid little trap door the UTG mags have, I like that a whole lot more.

Over all, I'm gonna give this gun a solid 9/10, only because the stock came a little loose in the box. Definatly gives TM a run for their money, and is coming up on a CA or ICS. The perfect model for a gun bridging the gap between an MPEG and an AEG.

As for upgrades I'd get, maybe a M110 spring (Any more and you will need to get metal bushings and possibly upgrade pistons), some extra Mags, and probably a 8.4 3300 mAh battery.

You can probably get away with using a 9.6v, but I don't want to try it...Someone else want to try and see what happens?
