[@connor3288]

@@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!

I would like to see a similar video explaining the difference between the original stoner gun piston design and the AK-47, i know there was a difference that used to make the stoner gun less reliable because of debris in the blow back gas.

[@khanbabu2635]

[@edilbertojrgerna6201]

isn't the blowback and recoil style of self cocking the same?

[@MadMaxTrac]

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.

[@flamingwheel9926]

Well yes, bur actually no

[@YouLookLoneIy]

We don't do that in here

[@baker90338]

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)

[@Beuwen_The_Dragon]

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.

[@Born2Losenot2win]

Can we do recoil electronically these days?

[@lizardlickcrowing4793]

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.

[@Born2Losenot2win]

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?

[@censorduck]

@@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.

[@Born2Losenot2win]

@@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

[@censorduck]

@@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.

[@downey2294]

I'm confused, what is stopping the bolt from going backwards before the bullet has left the barrel 5:55

[@slavachizh9972]

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

[@14goldmedals]

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.

[@downey2294]

@@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?

[@codetech5598]

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

[@namenandern5531]

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.

[@hoppinggnomethe4154]

[@moostasheman3756]

So thats how the top spring on the ak is for.

[@McCaroni_Sup]

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.

[@estefanocancino1759]

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

[@eduardodiaz5762]

Gunpowder exploded gas. Need I say more.

[@tomvanlin2356]

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

[@cheekibreeki904]

It only explains simple blowback, but not delayed blowback. Still a good video, though. Just a bit lacking.

[@Beuwen_The_Dragon]

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.

[@MadMaxTrac]

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.

[@soapman8970]

[@smorrow]

So.. I don't understand how a blowback-operated is ever in battery.

[@arma3koth290]

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

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).
