Straight Blowback Systems In Firearms 

If you are wondering what program I use for the creation of this video, please check the description. It should be included on every video in this series, if not let me know.

Me: interested in how guns and bullets work ATF: it’s interesting that your interested

Fantastic video. Loved the explanation of how the pressure causes the brass to stick to the chamber, which would either tear the rim off or cause an explosion if the gun tries to extract too early. For a long time I just thought it was so it didn't eject the brass hard enough to maim or kill anyone standing next to it.

Great video. It's amazing how simple the design is.

Dang that was one awesome, informational and educational video. Thanks for making it!

Damn, just learned about that game, going to download it ASAP

So here is the simplified explanation of how blowback operation works. It makes good use of Newton's third law of motion by using the opposite but equal reaction of the hot gasses pushing the bullet out the barrel to push the bolt back, eject the spent casing, and chamber the next round.

Great video, very educative explanation.

How much does the bolt weight? Can't find info anywhere

can you try the silenced Ruger 22LR

can u do how a PMR30 operates?

Great vid mate. Well done and thanks.

Thank you. I am studying gun design and this was very interesting.

It would be awesome if you could do a similar video on the John Browning A5 with a barrel that is spring loaded to and ejects the spent shell. The classic and world famous flawless humpback’ design

Some extra info regarding why the Tec-9 was so popular with the bad guys: More than the affordability you mentioned, it was the amount of firepower for its small size. It worked well as an intimidator, yes, any gun is scary, but this one could just hose out bullets making your chance to escape way less (even if the person firing it can't aim very well). Fun fact : the AB10 was a neutered version of this gun, and therefore became just a big clumsy handgun.

I am taking a forensic class: Firearms and Toolmarks, and your explanation and X-ray videos have helped immensely!!!

very educative, thank you very much.

Thanks for the video , could you do an explanation of the p90 please ?

Great videos

Bonds ppk was in 32acp was it not?

Finally got it, thanks for your vid!!

i love the tec-9. I think its simplicity is its genius

This is awesome

You should do a vid on the Vector .45

The bolt in such a system is not cloesed at all. It starts opening exactly when the bullet starts to move due to conservation of momentum. The trick is actually to keep the blowback action slow enough that the bullet can go all the way down the barell before the thin part of the empty case looses its support in the chamber.

Did you make these?

Would it be possible to make a straight blow back to assault rifle?

This is probably one of the simplest designs. The only part that would take a bit of skill to make, is the bolt. The rest is fairly doable. With 3D printers, making one of these would be awesome.

Hi their can you animate specter sub machine gun?

Thought the tec 9 is open bolt? Arent most compact smgs open bolt systems?

I wonder if it’s possible for a tank to have a system like this

Gostaria de fazer uma sub metralhadora

The Tech 9 can be considered a form of birth control in the lower income neighborhood .

Would you do a video on a specific firearm? Maybe for a cost?

Jiminez Arms .380 has the spring under the barrel and is out if business because someone didn't follow one of the 4 rules. Anecdotally, awesome gun: more reliable than a new highpoint or an old glock on my last target shoot.

Anybody else notice that it wasn't a dual recoil spring on the second gun. It was the striker or firing pin or whatever you wanna call it

Can SMGs, semi-auto shotguns, semi/full auto rifles & machine guns work same way?

dude thank you so much. you spoke clearly and it was easy to follow

I have cz model z 25 cal it doesn't has an ejector how it ejects the case

Hey now I can make my own blowback zipgun! Good thing it’s legal as long as I don’t sell it!

You had me at Mouse Gunner

Can 12 gauge shotgun can be blowback operated??

I've been really confused about what exactly brings the bolt or slide back in non gas-operated systems. I still don't really get it This is going to sound really stupid, but is it the force of the gas on the casing that blows the casing back at the same time propelling the bullet, and that casing being blown back is what resets the slide/bolt?

The chamber indicator on the PPK needs addressing.

Please make video about how recoiless rifle work

4:20 How/where does the force of the combustion act against the slide to send it rearward? Ian Mccullums video skips over this step too.

is that why 45 hi point is bulky

V e ry good mate. A stronger spring would of been twice as strong t h ough

what program is this?

0:13 hehe pee pee good vid tho

How does a CO2 power blowback work ?

Is straight blowback systems only for pistol calibers

Im designing my own open bolt bullpup smg rn for fun

after viewing the slider mechanism and then seeing the tech, it's hard not to instantly love the tech, It VISUALLY MAKES SENSE, slider way too complicated gross, added complications. You just know when you see something and it works and makes sense!!!!!

at 0.75 speed it sounds like you're a drunk professor

This could have been a beautiful four minute video

those menus look like Runescape

Thousanth like🤘

Ok nice post.

James Bond didn’t have much say in the matter. Q picked it and M made James take the PPK and leave behind his Beretta .25. In Dr No the book, James was actually pretty pissed about it

You can make blowback machine guns in your shed lol

The only thing that I don't like about auto-loaders is they get burnt powder everywhere.

This should have named SlinkySpring

simple, yet still a better mechanism that many modern rifles

I bought a 9mm Hi-point as a personal experiment, many years ago. The direct blow-back action is not good in pistols for anything except 380 and below. The 9mm slide is already too heavy, and noticeably worse to shoot that any other modern handgun I own in the same caliber or higher. In addition, the Hi-point had a ridiculous number of lands-and-grooves (>8). When I shot lead roundnose handloads through it, it just sprayed lead all over the place inside the barrel. It was not possible to clean it out in a reasonable amount of time without damaging the barrel. Hi-points, or any blow back pistols, are good throw-away guns. Shoot it, kill someone, then you also don't feel bad about disposing of the gun in the garbage. Because that's what they are. Garbage. I choose a higher path. I will only shoot and keep good guns, and if I need to shoot garbage, I will expect my high quality firearm back in my possession at the end of the legal inquisition. Now, this discussion of blow-back is only limited to pistol calibers. In rifle calibers, the direct-blowback action is actually pretty common and good. Like HK. Many consider it better than the AR and AK rifle action. That is another discussion...

I can .ake a gun now.

One of Veronica Rodriguez in spiritual says for kidnapping kids in sacrificing them evil with his tarot stuff I'm serious

Animation is great but presentation is useless. I wish there was just some arrows to tell me which direction the narrator is talking about.

This shows how pistol work , but not explaining how the blow back work ?

also...straight blowbacks don't need extractors...
