The PK (Russian: Пулемёт Калашникова, transliterated as Pulemyot Kalashnikova, or "Kalashnikov's machine gun"), [4] is a belt-fed general-purpose machine gun, chambered for the 7.62×54mmR rimmed cartridge. The modernized and most commonly known variant, known as the PKM, features several enhancements over the original PK design.

The Type 80 (Chinese: 80式通用机枪) is a general-purpose machine gun (GPMG) manufactured by Norinco in China, based on the Soviet PKM. The machine gun was certified for design finalisation in 1980 and entered the PLA service in the mid-1980s, specifically in 1983. [5]

PKS／PKMS是配轻型三脚架作重机枪状态的PK／PKM，任何PK或PKM都可以加上三脚架转换为PKS／PKMS。 PKT／PKMT是在坦克上用作并列机枪，没有握把和枪托。 采用PKT的装甲车辆包括T-72和T-80主战坦克及BMP步兵战车。 PKB／PKMB是车载机枪，其实就是以车辆上的武器支架代替PKS的三脚架。 在冷战时期，PK系列机枪广泛分布到世界各地，并在许多地区冲突中使用。 PK系列机枪也被许多苏联/俄罗斯以外的国家生产，如：保加利亚、匈牙利、罗马尼亚、中 …

1960年代誕生的 FN MAG （MAG-58）、 MG3 、 PK／PKM 亦是著名的通用機槍之一，在各國軍隊中最為常見。 由於美國主導西方國家全面接受 7.62×51mm_NATO 規格彈藥，西方國家的通用機槍在冷戰中期以前都是以該規格子彈為主要運用彈種。 美國 對於通用機槍的知識吸收與內化時間較慢，至1950年代後期才研發出 M60通用機槍，至1970年代才汰換 白朗寧M1919中型機槍 血統的車載機槍，全面換用MAG的授權版 M240通用機槍，然而M60技術始終無法讓美軍步兵所肯 …

The PK is a 7.62 mm general-purpose machine gun designed in the Soviet Union and currently in production in Russia. The PK machine gun was introduced in the 1960s and replaced the SGM and RPD machine guns in Soviet service.

2012年12月14日 · Modernized PK machine gun (PKM) In 1969, the design was revised and given the new designation PKM (modernized), along with the PKMS and PKMT. The new version was lightened to 16.5 pounds (down from 19.8), and can be distinguished by a short flash hider, smooth barrel, and ribbed top cover (the original PK has a half fluted barrel, smooth top ...

1998年5月1日 · The PK/PKM series has changed into four configurations: The PK/PKM is a basic LMG version with bipod. The PKS/PKMS (PKS – Pulemyot Kalashnikova Stankoviy) is a tripod mounted PK/PKM. Every PK or PKM can convert to a PKS/PKMS while it is placed on the tripod.

The PKP Pecheneg machine gun is a modernized version of the PKM with a forced-air-cooled, non-changeable barrel that allows for longer periods of fire and greater accuracy. Further improvements include the shifting of the bipod towards the muzzle to improve stability, and the capability to mount optical sights.

The PKMN (ПКМ Ночной: "PKM Night-Vision") is a variant that can mount a night sight for low-visibility operations. The PKMN-1 can thus mount the multi-model NSPU-3 (1PN51) night vision scope while the PKMN-2 can mount the multi-model NSPUM (1PN58) night vision scope.

pkm的优点：重量轻（只有m240的一半），精度高（始终力压m60，尤其是在用弹性枪架的情况下），空间利用合理（供弹拨杆设计非常巧妙，双程供弹比西方一票单程供弹还紧凑），可靠性好（毕竟自动机和ak一样，带动平面双凸榫刚性抛壳挺一个不少），成本低 ...
