How a PKM Machine Gun Works

Wikipedia: The PK (Russian: Пулемёт Калашникова, transliterated as Pulemyot Kalashnikova, or "Kalashnikov's machine gun"),[2] is a belt-fed general-purpose machine gun, chambered for the 7.62×54mmR rimmed cartridge.
Designed in the Soviet Union and currently in production in Russia,[3] the original PK machine gun was introduced in 1961 and the improved PKM variant was introduced in 1969. The PKM was designed to replace the SGM and RP-46 machine guns that were previously in Soviet service.
The weapon remains in use as a front-line infantry and vehicle-mounted weapon with Russia's armed forces and has also been exported extensively and produced in several other countries under license.

One like is not nearly enough for such a tour de force!
Outstanding video!
Truly worthy of the engineering masterpiece that is the PKM!

Thank you

[@useemehere2]

Wow so amazing to see how it works 360 degree view

[@KingOfYourMouth]

Oh wow this is very nicely done.

[@americangangster1911]

Thanks, it's a program/game that you can buy on steam.

Ahh so that what makes a machine gun fire so fast thres two spings at the left and right

[@user-kc4cm3jm4t]

Well done. But what might not be understood from your video, is that most of the parts (other then field stripping) are designed to NOT disassemble. Every pin is effectively a rivet. And once removed, should be replaced with a new one; which is then expanded (like a rivet) so that it cannot drift out under vibration.

please show the ejection ports

Good ❤❤❤

[@TellenJones]

It's gas-driven, different from MG42 or SAW. Interesting.

Да, но у пламегасителя на стволе левая резьба

Bolt handle dont link with bolt so how to pull back the bolt handle bolt move and bolt handle dont move when shoot?

[@americangangster1911]

Yes that's called an non reciprocating charging handle. The charging handle pulls the bolt backwards, and then it moves forward and clicks into place so it's out of the way.
