The SKS is a Russian semi-automatic carbine, designed in 1945 by Sergei Gavrilovich Simonov. It is formally known as the Samozaryadnyi Karabin sistemi Simonova ( Russian: Самозарядный карабин системы Симонова), 1945 (Self-loading Carbine, Simonov's system, 1945), or SKS 45. It was originally planned to serve as the new standard issue weapon for the Soviet military forces, alongside Mikhail Kalashnikov's new AK-47 design, to replace the Mosin-Nagant series of bolt-action rifles and carbines that had been in service since 1891. As mass production of AK-pattern rifles increased, the SKS carbine was soon phased out of service. The carbine was quickly replaced by the AK-47, but it remained in second-line service for decades afterwards, and remains a ceremonial arm today. It was widely exported and produced by the former Eastern Bloc nations, as well as China, where it was designated the "Type 56" (and, in modified form, the "Type 68"), East Germany as the "Karabiner S" and in North Korea as the "Type 63" It is today popular on the civilian surplus market in many countries.
The carbine was chambered for the then-new 7.62 x 39 mm M1943 round, an intermediate cartridge which went on to be used in the Kalashnikov-series weapons.
While early Russian models had spring-loaded firing pins, most variants of the SKS have a free floated firing pin within the bolt. Because of this design, care must be taken during cleaning (especially after long storage) to ensure that the firing pin does not stick in the forward position within the bolt. SKS firing pins that are stuck in the forward position have been known to cause accidental "slamfires" (uncontrolled automatic fire that empties the magazine). This behavior is less likely with the hard primer military-spec ammo for which the SKS was designed, but as with any rifle the user should properly maintain their firearm. For collectors, slamfires are more likely when the bolt still has remnants of cosmoline embedded in it.
In most variants (Yugoslav models being the most notable exception), the barrel is chrome lined for increased wear and heat tolerance from sustained fire and to resist corrosion from high sulfur corrosive primed ammunition, as well as to facilitate cleaning. Chrome bore lining is common in military rifles, although it can diminish accuracy. Yugoslav models do not have chrome lined barrels due to the fact that there are no significant deposits of chromium in the country, and even though Yugoslavia was allied communist at one time, had unreliable relations with the USSR. The USSR was one of the largest exporters of chromium.
All military SKSs have a bayonet attached to the underside of the barrel, which is extended and retracted via a spring-loaded hinge (some are removable whereas some are permanent). The SKS is easily field stripped and reassembled with no tools. The rifle has a cleaning kit stored in a trapdoor in the buttstock, with a cleaning rod running under the barrel, in the same style as the AK-47. In common with other Soviet-era designs, the SKS trades accuracy for ruggedness, ease of maintenance, ease of use, and low manufacturing cost. In short, it is a simple design that is highly effective and rugged.
For some shooters, the rear sight on the SKS has too small of a notch for accurate shooting, even in good light. Replacement with an inexpensive peep sight is easy and popular. Another popular, and even less expensive workaround for this issue is to apply a tiny amount of bright colored nail polish to the front sight post (or replace the front sight post altogether with a bright colored secondary market (commercial) post. For other shooters, the original buttstock is too short. However, this can be easily replaced with a better fitting composite buttstock as well.
In 1949, the SKS was officially adopted into the Soviet Army, produced at the Tula Armory until 1955 and the Izhevsk Armory until 1954. Even then, though, its days were numbered. Gradually over the next few years, the AK-47 increased in number until the SKS was primarily used by non-infantry and second-line troops. This continued to be the case even as late as the 1980s and possibly the early 1990s. To this day, the SKS is used by some ceremonial Russian honor guards, and is nearly as ubiquitous as the AK-47 in civilian hands as well as third-world militias and insurgent groups.
During the Cold War, Russia shared the design and manufacturing details with its allies. total, SKSs were manufactured by Russia, China, Yugoslavia, Albania, North Korea, Vietnam, and East Germany (Kar. S) with limited pilot production (Model 56) in Romania and Poland (Wz49.) Physically, all are very similar, although the NATO-specification 22mm grenade launcher of the Yugoslav version, and the more encompassing stock of the Albanian version are visually distinctive. Early versions of the Russian SKS and later Chinese Type 56s (produced 1965-71) used a spike bayonet, whereas the majority use a vertically-aligned blade. Many smaller parts, most notably the sights and charging handles, were unique to different national production runs. A small quantity of SKS carbines manufactured in 1955-56 were produced in China with Russian parts, presumably as part of a technology sharing arrangement. Many Yugoslav M59/66 series rifles were exported to Uruguay and Mozambique; the Mozambique versions having teakwood stocks, the wood supplied by that nation. The vast majority of Yugoslav M59 and M59/66s have elm, walnut and beech stocks. SKS carbines have also made appearances in recent conflicts in Africa, Afghanistan, and Iraq.
Nations that utilized the SKS but did not receive manufacturing rights included Afghanistan, Congo, Indonesia, Iraq, Laos, Lebanon, Mongolia, Morocco, the United Arab Republic (Egypt) and the Yemen People's Democratic Republic.
The SKS has also been featured prominently around the world during times of civil unrest. In the United States, the SKS was used successfully by Korean shopkeepers to fend off looters during the 1992 Los Angeles riots.
NOTE: All SKS variants except for the Yugoslav M59/66 are carbines. This is due to the additional length that the flash hider/grenade launcher attachment gives to the SKS.
Differences from the "baseline" late Russian Tula Armory/Izhevsk Armory SKS:
There is some debate as to the relative quality of each nation's SKS production; Yugoslav types are generally considered to be better made than Chinese, yet the Chinese types typically have chrome lined barrels while the Yugoslav versions do not. East German, Russian and Albanian SKSs bring a higher price than those of other countries, the stock on the Albanian versions being of a slightly different manufacture and being rarer due to low production numbers. There were approximately 18,000 Albanian SKSs manufactured during the late 1960s until 1978, and of those, approximately half were destroyed. Most of the remaining East German SKSs had been sold/transferred to Croatia in the early 1990s.
A sporterized hunting version of the SKS is still manufactured in Yugoslavia, by the Zastava Armory. It is designated the LKP 66, and features a "Monte Carlo" style one-piece stock, receiver mounted scope mount, modified trigger, and flush-fit 7 round magazine. It also has a redesigned front sight with no bayonet mount. This rifle has not yet been imported into the US.
The SKS is popular on the civilian surplus market, especially in the United States, where examples range in price from roughly US $100-$500 depending on type, history, quality, availability, national origin, and location of purchase.
Unlike other military rifles, the SKS has not attracted a significant degree of negative publicity. Its inexpensive price and wide availability make it a popular firearm and the gun is certainly used by criminals. It was widely and incorrectly reported as the murder weapon in the November 2004 shootings of six hunters in the North American state of Wisconsin.*. The actual firearm was a sporterized Kalashnikov variant made by Saiga/Izhmash and chambered in 7.62x39.
