How A Russian PKM Machine Gun Works (World Of Guns)
ฝัง
- เผยแพร่เมื่อ 9 มิ.ย. 2020
- (Wikipedia) The PK (Russian: Пулемёт Калашникова, transliterated as Pulemyot Kalashnikova, or "Kalashnikov's machine gun"),[15] is a 7.62×54mmR general-purpose machine gun designed in the Soviet Union and currently in production in Russia.[16] The original PK machine gun was introduced in 1961 and then the improved PKM in 1969 to replace the SGM and RP-46 machine guns in Soviet service. It remains in use as a front-line infantry and vehicle-mounted weapon with Russia's armed forces. The PK has been exported extensively and produced in several other countries under license.

Sometimes you wake up at 5 am and just have to know what the funny little bolt claw on a PKM actually does.
Предполагаю, что по утрам она блокирует спуск
This really is a unique firearm, huh? Feeds from the right, ejects from the left. Strips the rounds backwards down into the chamber. Ejects and strips a new rounds pretty much at the same time. Open bolt position. Neat af.
Older machine guns like the Maxim had a similar system where they pull the bullet out of the belt.
Most fascinating thing to me is that this is both an open bolt and a long stroke gas piston gun. I cant think of any other open bolt gas operated firearms (though I'm certain there are others)
@@Ezekiel_AlliumM240 and M249. RPD as well.
@@johncarl5505 I wont lie I thought the RPD fired from a closed bolt
It doesn't particularly matter which side the ammunition feeds from, it's usually just about convention depending on the location/experience of the designer. What I find most interesting about the PK/M is that it doesn't use a 2-piece disintegrating link system like the M240/M249 (American/European) designs. Instead, the PK/M design works by plucking the 7.62×54R backwards out from the link (during the extraction step of the previously fired cartridge), holds it in place behind/under the feed tray, then rams it home when the trigger is depressed. Also, you need the operating system to run as an open bolt due to barrel heating from sustained high-cyclic-rate fire possibly cooking off a round (where the heat from the barrel gets the gunpowder in a cartridge hot enough to self-detonate without touching the primer.) There are systems out there that operate with a closed bolt, but they are nearly all designed with more heat dissipation and lower cyclic rates to prevent cook-offs.
The most impressive thing about these guns to me is that they were designed around 63 years ago (from the date of this post) in 1961. And considering the guns are chambered for a round that was designed in 1891 (the 7.62×54R [in which the "R" designates it as a rimmed cartridge rather than the misattributed "Russian"]), it's got a long proven track record with 132 years of service.
Got to appreciate that every power intensive task is done on the back stroke, by gas pressure, rather than on forward stroke by the spring that can be broken.
Stripping the cartridge back from the belt, extraction, ejection. All thats left is to feed the cartridge.
Genius is in the feed pawl design. All western MGs have copied the WW2 German MG42 design of top cover, with its push through belt. The Russians kept their Pull Out belt from the Maxim 1910 and found a much more compact system.
As a result the PKM is smaller/lighter than any western design. The only weapon that comes close is the M60 but that system was abandoned due to reliability concerns.
I love PK but I don't like ejection shell from left side of PK cause when handheld it and shooting the Hot Shell eject from left side of gun will hit arm, I don't know why they don't use base design from RPD that felt belt from left side and ejection shell on right side of gun.
@@captainnutt2995 Because that isn't a concern in any military. 95% of the time you're gonna be shooting prone with it anyway and even if you would shoot standing or kneeling the casings would just hit your arm that is covered with clothing and bounce off.
I do not understand at all why the West began to copy the MG-42 so massively, and to introduce its ideas into its designs? In 1943, the Americans released an educational film in which they criticized this machine gun for its high rate of fire. And then we went this way anyway th-cam.com/video/ary0Pe4zn_o/w-d-xo.html
@@captainnutt2995 I have never experienced any discomfort from the design feature you mentioned
The feed pawl on the PKM (a literal claw which pushes the belt and can be seen at 2:26) is actually Western😂. It was patented by Louis Stange in the 1920s.
Unique firearm of the Soviets ❤️
Beautiful
Perfect and thank you!!
Simple but truly interesting ❤️
What did you studied to design this awesome machine gun
I mean that how to design machine guns from sketching to prototype
It's a game called World of Guns on steam.
@@americangangster1911 ohh!!
I thought it is educational program for real machine guns 😅
It's kind of an educational program and a game but it has many different guns. I heard they have it for mobile devices too, search "World of Guns" on the app store.
@@americangangster1911 ok bro thank you 💙⚡💙
The spring works so fast
Big AK boolet.
Please share with me a book for making fire arms
EPIC
after the shot. the impact of bullet save to make unlimited shot.
Such nice gun, i have asg replica and was curious how real one works
Do all belt feds strip the round from the belt before firing it?
No, because 7.62x54r is rimmed cartridge this pull and loud method allows pkm to use older and simpler belt at the cost of gun being slightly more complicated.
Most machine guns push the round forward through the belt which isn't really possible with the big rim that this round has around the base.
@@someguy4439 Almost all modern detachable tapes (1 link each) based on the 1918/24 Vickers tape. So this is not such a fresh invention
Basically AK but upside down lol
Not even close
look at how it feed round
does AK do that?
What is the name of this application ??
World of Guns, it's a game that you can buy on Steam and it's available on mobile devices.
And mobile
2:00
This machine can fire
Might be one of the best WW2 machine gun lmao
looks so old
