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.

2020年6月24日 · Both weapons use the long-stroke gas piston operation, where gas is tapped from the barrel to drive a piston that actuates the action. On the AK, the gas tube that houses this piston is above the...

2007年10月18日 · The PK series is a belt fed Kalashnikov design in 7.62x54mmR, and is more a General Purpose Machine Gun (GPMG) vs. a Squad Automatic Weapon (SAW), which is what the RPD was designed for.

当1969年推出改进的PKM时，就配用了一种由利昂尼特·斯特柏洛夫（Leonid Stepanov）设计的重量更轻的新型三脚架。 斯特柏洛夫的轻型三脚架大部分由构件由钢冲压而成，重量只有4.5kg，这种柔性枪架上没有任何缓冲装置，枪架直接与横向/竖向机构相连。

2012年12月14日 · Mechanically, the PK is basically an AK action flipped upside down, to allow for a belt feed on the top of the receiver instead of a box magazine on the bottom. Like the AK, the PK makes clever and effective use of design elements from several other guns.

2023年4月8日 · 比较明显的区别就是PK机枪带有纵向凹槽的枪管，变成更加容易生产的外表光滑的枪管。 安装在TKB-056三脚架上的TKB-015机枪。 顺便说一句，尼基京吸取了竞标失败的教训，在他已经被苏军装备的NSV“悬崖”重机枪的闭锁结构基础上，研制出一款重量更轻的TKB-015机枪，重量略超过6千克。 但这样彻底轻量化的设计让机枪缺乏必要的可靠性，此外，在发射7.62×54mm这样的中口径全威力弹药时，仍需要一些必要的重量以提高射击的稳定性。 FN …

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 ...

2024年11月4日 · There are plenty of articles about the history of AK - from actual research to schizophrenic fantasies. However, there is almost nothing when it comes to another, arguably better gun developed by Kalashnikov - PK GPMG. I gathered years of research about PKM history and am currently writing a series of articles about it.

2023年2月18日 · When a reenactor or a collector grows to the point when he is ready to purchase a GPMG for his Soviet-Afghan collection, an important question comes to mind. Which machine gun fits best - old PK or his modernized younger brother? The answer is not exactly obvious.

2007年7月13日 · would a PK kit be buildable on the VLTOR receiver?? what is the difference between the two?? what parts can interchange?? barrel?? The PKM has a lighter barrel, otherwise, it should work just fine. Receiver is different too, compare them in terms of rivets etc.. The dimensions of the receiver and internal parts look the same.
