Fundamentals of Small Arms Weapons (part 2 of 3) Types of Operation 

Very good way of putting it. I knew the names of the parts of firearms and what they do but I've never actually had it demonstrated and explained in a coherent manner that's not just throwing around jargon expecting you to be able to piece it all together..

Except for car engineers they dont account for shit. "Oh you want to change that oil filter too bad you have to remove the engine to get to it"

@@Sabi1234567890Asdf i know you are exaggerating obviously. I have never worked on a car with a what i would call difficult to service oil filter. Yes some are inconvenient, like tacoma/tundra cartridge filters, ford f150 filters due to the cleanup, ram v8s same reason, many nissans same, honda v6 same. This is working at a shop with a lift mind you. There are much more brutal "battles" in auto repair. Btw im in the northeast, toyota alignments involve an oxy ace torch 75% of the time. Many cars over 5 yrs, some newer, cant be properly aligned due to adjustment seizure from rust. I would argue the oil fill cap alone is much worse engineered on many cars, like the newer vag ones that wont take a funnel, or gm v8s that are at an angle making a funnel need to be held so it wont fall off. You should see whats involved in simply changing a headlight bulb in some newer cars. A coworker did headlights on a bmw once, had to replace both complete units, was thousands for the customer, dont buy bmws folks!

Your just hearing propper pronunciation and clear speaking. Mostly because they had to borderline shout into the very first microphones. That's why old westerns sound that way. It just seems serene or foreign to you because we got idiots that eat tide pods setting trends. Instead of young men wanting to be stoic grown men.

Hmmm, it depends. Gas operated weapons tend to be more reliable for larger weapons, like rifles and high calibre pistols. Blowback tends to be reliable in low calibre weapons like pistols and submachine guns

Yeah, AKs are gas operated. The barrel is a bit lower in relation to the sights because Kalashnikov decided to put the gas port on top of the barrel rather than under it, just like the STG-44 built mere years earlier and unlike the M1 Garand. This is due to better heat management necessary for full auto fire since the gas tube won't have to contact the handguard, another reason being so as to not get in the way of a magazine. AR style rifles also have their gas tube on the top, though it is not exposed as it is on the Kalashnikov, but concealed in the handguard.

Blowback usually refers to the cycling that doesn't have a chamber locking mechanism, but any inertial or recoiling type, including blow back can re-cock the firearm.

Well yes, bur actually no

We don't do that in here

edilberto jr gerna recoil style has a locking mechanism (look at the M1911) while blowback is more locked by the mass and spring pressure of the action (see a similar weapon to the M1911, the m1903 hammerless)

Blowback has no locking mechanism, as it relies only on the weight of the bolt and pressure of the return spring, and is intended for low pressure cartridges only. Recoil has a locking mechanism, similar to a gas system. Only instead of using gas to push a piston, the recoil itself pushes the barrel, extension and bolt back into the receiver together, (keeping the high pressure cartridge inside the chambre), till it reaches the point of unlocking the bolt from the barrel. Basically, gas/piston and recoil/locking are the two different approaches handling both low and high pressure cartridges, while blowback can only handle low pressure cartridges.

Lol nice

Amir Some do, yes! Some larger more complicated weapons use electricity for cycle of operations, some tanks and aircraft weapons in fact use electric motors to drive cycle of operations. They would use a motor because typically you cannot have to direct contact to some weapons while on certain platforms, so you need a way to cycle the weapon automatically (Heavier Ordinance has a slightly different cycle of operation than this video). Typically, man portable weapons (Rifles, pistols, machine guns ect) do not use electric motors for operation due to weight and reliability.

LizardLick Crowing So even the reliability is lessened? Hmm, and if we would’ve resolved those two factors, do you think it would worth the cause? Would it be worth the extra cash? Because trying to use the throttle energy of a bullet for recoil seems inefficient, performance wise, like how snipers need manual recoil for a better performance, so I was wondering if any big company out there would think of making them in the future or they would stick to the old ways Edit: I did a search and came across a couple of these companies but do you think this new field of technology would spread out to other suppliers and markets?

@@Born2Losenot2win Thing is,, having electric systems in an infantry weapons means that the infantryman needs to carry a power supply. It also means a higher degree of complexity that might not necessarily make weapons more reliable or effective. I don't necessarily think that more electronics in rifles would be bad, but I think there are some difficulties to overcome.

@@censorduck ah yes, the power supply, silly old me, he didn’t thought about that, an EMP could also destroy the entire circuit, so we’re not there yet

@@Born2Losenot2win well I'm sure you could make a rifle that is isolated from such attacks. But even if that wasn't an issue, having a seperate power supply would be an issue unto itself. There are also environmental concerns to the reliability of an electronic system.

By this point in the 1940s, delayed blowback wasn’t really a thing yet. The most common delayed blowback design was a product of the Spanish and later German designs of the 1950s, being the ‘roller delayed” blowback. That said, recoil operation could be considered a type of delayed blowback, as the locking mechanism delayed the bolt opening, and the entire mechanism recoils from the blowback. But that’s if we want to play fast and loose with the technicalities.

yes, strange, no one word about it in all 3 films:-/

dutch hi, it's a blow back action. There are no locking lugs just a heavy bolt mass that allows the bullet to be gone and the gas pressure dropped safely but the initial energy starts the bolt back and cycles the action. NOTE: only for low pressure rounds like 9mm or 45 ACP for example.

@@14goldmedals in the video the bolt only blows back once the bullet has left the barrel. it doesn't make sense to me, shouldn't the bolt move back at the same time that the bullet gets fired? or is the bolt weighted to make it move slower then the time it takes for the bullet to leave the barrel?

*Inertia.* The bolt is much more massive than the bullet so it accelerates much slower.

Simple physics: the explosion in the cardridge exerts the same energy backwards and forwards. But the bolt is heavier than the bullet so it moves less fast than the bullet which gives enough time that the pressure in the barrel is on a safe level.

From the cartridge the same case that pushes the round out the weapon

Gunpowder exploded gas. Need I say more.

when the bullets is fired the gunpowder burns and creates gas that gas is enough to push the bolt back.

Fixed, thanks :)

it isn't, the weight of the bolt is enough to keep the case in the chamber while the bullet is fired, the momentum of the bolt then cycles the gun. this is only pistol rounds use blowback, larger bullets would require a super heavy bolt to operate safely

Not unless it violates a patent, most of these old designs have already expired and are copied all over the firearms industry. It is not my intent with these videos to show people how to build a firearm, I don't recommend it to any amateur. If you do want to build your own firearm make sure you follow your local laws, and have a licensed gunsmith check out your firearm before you fire it.

@@MadMaxTrac oh..okay thanks so which mean if I copy all of it will resulting law suit? So which I have to redesign the bolt and entire part? No I didn't intent to build firearm yet,i was intent design one and see if I could get Gorvement interested,I form malaysia so I not permitted to do as well but design,I geuss it can...so anyway thanks for remind and knowledge sharing wish could see more and learn more form your channel..thanks again 🙏🙏🙏

I refuse. Gas operation is the best. There's a reason why the Advanced Combat Rifle uses a gas-piston system rather than direct impingement like "normal" AR-platform firearms. Plus, you don't need to worry about having a tube at the back to store your spring (and I'm better-versed at the fundamentals of gas operation than of direct impingement and other strange firing systems if you couldn't tell).

@@commanderfoxtrot direct impingement is also gas-operaged, though 🤔

@@cheekibreeki904 it uses gas, sure, but not a piston system.

@@commanderfoxtrot that's the definition of gas-operated firearm. Long stroke, short stroke, direct impingement, whatever - if it uses gunpowder gases, it's gas-operated.

@@cheekibreeki904 yeah, but nobody thinks of impingement as gas operation since it’s cursed and less-effective than gas-piston.

Certainly it might sound corny but it is a well paced and clearly delivered, designed to communicate rather than impress with speed and special video/audio effects. Much to learn here for many other would be instructional video makers.
