How Semi-Auto and Full Auto Rifles Work

An old film showing slow motion cut aways of semi and full auto fcg's while in use.

[@ScoobieDoobieDoob]

The thing about old informative/educational videos is that they assume you know absolutely nothing. So, they always teach you from the ground up with basic terminology, and explain any bizarre vocabulary.

[@robertmartin8907]

This is from the 1950's, people back then literally didn't know anything.

[@ambi_cc8464]

@@robertmartin8907 it’s not that they knew nothing, it’s just that they didn’t have quick access to lots of knowledge like we do now so they just made it to where no matter what part of it you knew, you could understand it anyway

It's like 75 years old actually lol

[@Yora21]

That's a really nice model they made for the demonstration. Even in black and white it's much easier to see what's going on than with fancy 3D computer models you see today, which show way too much other stuff in an actual gun that isn't part of the mechanism.

Dk Kevorkian I love the way they showed it with a model ...

[@potc420]

I know right!? I love these old vids. This one kinda reminds me of that "how a differential" works video I've seen floating around on Facebook a few times

[@Peagaporto]

anyone got a full collection of these mechanical videos?

[@klendathusfinest4126]

I literally found this trying to find out why full auto Nerf guns need batteries and real full auto guns don't. Was not disappointed.

[@turboshaft1959]

Lesensketch in a real gun, the energy required to accelerate the projectile is stored in each shell. a little bit of that energy is used to cycle and load a new round. however, nerf "shells" are only "bullets" with no energy stored. so you need to add another form of energy, in this case electricity, to cycle a new round. The electric energy is also used to accelerate the dart. In semi automatic nerfs, you add the cycling and firing energy by hand. it gets stored in a spring and released when you pull the trigger.

[@klendathusfinest4126]

Thanks for explaining it in more detail. Thanks to the video I was able to understand that real guns use the energy from the shell's explosion to move the mechanism, so it no longer requires manual action or electricity

[@Skyfighter64]

The funny thing is that, say in late 90's Nerf full auto designs, they were still fully air powered. Not anything as neat as the new belt-fed NERF guns, but interesting in their own right.

[@qoph1988]

@@klendathusfinest4126 Yeah. Nerf darts don't contain chemical potential energy. Well, maybe just a little bit if you set them on fire but I'm guessing they mostly melt. A gatling gun or more modern minigun does need a motor (or a conscript with a hand-crank) to make it work, though.

[@SpaceMarine113]

@@qoph1988 the motor is needed for a faster rate of fire to rotate the drum, but it's not required for the firearm to function. It's just that you won't be able to achieve such a high rate of fire on a normal full auto rifle.

[@bryanstephens3562]

Leave it to the Army to explain things so even a 19 yr old guy can learn it.

[@spoilersincominghoide9582]

Bryan Stephens These videos are so informative that even 8 year olds can understand and learn it.

[@donjuan6118]

A 19 year old in the US is already sexualy active, can buy cigarettes, and has hundreads of hours behind the car. What I'm trying to say is that a 19 year old in the US may already have and STD/STI, has probably started a long road of addiction to a death by cancer, and probably knows the best place to drive the car you gave him/her through a crowd. But they shouldn't know how mechanics work? And as if an 8 year old will carry out a semi automatic to automaic conversion. There are too many helicopter parents now to prevent that from happening.

[@moncorp1]

Donald Lanoux ~ I didn't see where anyone said a 19 year old shouldn't know these things. What are you questioning?

[@donjuan6118]

[@blakewooley2500]

Very educational. It's funny how so many people use firearms, yet they don't even know how they work.

[@bearly1727]

For years I was one of those people until a friend asked me to help him with a malfunctioning firearm. It opened my eyes and after watching countless videos on KZbin I am helping others and myself fix minor issues simply because I now understand how they function. I am NOT in business but I help for free. If replacement parts are needed they pay for the part and nothing else. Some I have looked at were just filthy and hadn't been near an oil bottle in 50 years so I try to get them to clean their firearm at least once in awhile. Not surprisingly, many don't know how.

[@hritikvaishnav603]

I have to say. This old video is much much better in explaining the mechanism than modern 3d videos. Agree?

[@Captain_Vitorio_Muscovy]

The problem with some modern 3D mechanism explanation videos is that some are more focused on weird camera angles and look unfinished or rushed, whoever produced them doesn't really seem to care if people understand it or not. I saw a Cat® video about differential steering and the video quality was 240p on their official KZbin channel, the mechanism could not be visualized well (the explanation was ok) and only through intense research on other websites I found a detailed diagram to understand the mechanism (I am addicted to studying and working on machines). Have a great Day/Night

[@whomagoose6897]

@@Only_God_Is_Allah_SWT: Slavery in America was on it's way out due to inventions of agricultural machinery. Starting with Eli Whitney's cotton gin. That one machine did the work of at least 120 people. Next was steam powered tractors that pulled plows far wider than a team of horses could ever do. Further reducing the need for labor. Every horse team needed at least one driver. One modern tractor & plow can turn over the soil in an 60 foot row. One modern tractor & plow can do more work in one day than a guy guiding a plow could do in two weeks with a team of horses. Just look at the mechanisation used to make automobiles. With the current highways transportation of products is cheaper, faster and way more efficient. Cotton is still marketable product. No longer hundreds of slaves needed. Cotton combines can harvest about 800 tons of cotton every day. My grandparents harvested their cotton by hand. A good day was 75 pounds of cotton per day by one person. Slavery was only a form of cheap labor. Just like today cheap labor is needed. As the cost of labor increases and machines can replace humans. Humans labor is replaced, perminently. Remember this when you hear demands of $15 per hour minimum wage. With machinery the fast food industry has eliminated ⅓ of it's labor requirements. Just by putting those kiosks in the McDonald's restaurants you hardly see more than one person at the order counter anymore. Civil War or not slavery was on it's way out.

[@lrodriguez6691]

@@Only_God_Is_Allah_SWT for your information , slavery happened worldwide, involving all races ...yes whites were slaves too..and it was a normal and accepted .tendency through history ...the result of the "way of conquer " where tribes first and nations later fought for power. The American Revolution created the path to destroy slavery for the first time on history declaring that all men were created equal and creating a way of government to organize society and allow law and order, creating a constitution to limit the government's power to control the People....meaning giving the people freedom. Today people like you undermine that constitution and give more power to the government, allowing slavery to come back , but this time the Government are the masters and all the people the slaves...like in Fascism and communism. ...
