The myth I hate the most is that bullets have the kinetic energy of a wrecking ball causing people to fly 5 feet in the air after getting hit. Only Chuck Norris' legs have that kind of power.

If the people who made this knew anything about guns it would probably be better.

No, your barrel will not burst into flames.

When I was in the Army, some guys hooked up five belts to a MG with an old worn out barrel that was to be thrown away, just to see what would happen. It shot cleanly all the way to the end of the 1,000 round belt without stopping, jams or misfires. The barrel was just starting to glow a bit by the end.

What happens is you burn out the threads if you fire repetitively for a long time, but actually melting the barrel is pretty much impossible (and metal doesn't burn morons).

Silencer on a shotgun? http://www.youtube.com/watch?v=-cz8uZWtt3Q

Works pretty well, not as quiet as the movie, but not excessively loud.

I'm not going to watch further, because this video is spreading as many lies as it clears up.

I have to agree...they don't seem to know what they're talking about....but
What might happen is the plastic/wood in direct contact with the barrel could burst into flames. I would guess that's why most (all?) true machine guns are all metal construction, but some idiots convert semi-auto guns with wood and plastic parts to full auto...asking for trouble.
And yes, while some 'silencers' don't do much, others drastically reduce both noise and muzzle flash. The mouse fart is overdoing it, but so is the demonstration shown where is seems there's almost no reduction.
What they missed is the idea that you can install a 'silencer' with 3/4 turn in 1/4 of a second. A real 'silencer' that's removable (really called a suppressor, because that's what they do) will have fine machine threads and need 5-10 full turns to be seated. Most movie 'silencers' would fly off with the first shot, silencing nothing and probably damaging the gun.

Not with a 3 lug silencer.

Not without their drawbacks, but they can be installed with a quarter turn.

You can buy one here to mount to your silencer for $150

OK, but it seems you still have to turn your quick connect piece the same 5-10 turns to attach it to the barrel, and the other side on your suppressor also needs 5-10 turns, adding how much extra weight...all to leave you with a gasket less compression fit (to a dirty barrel end/fitting end) rather than being screwed tightly on. I see a lot of drawbacks there for barely any positive.
I'm not sure if I think that counts, and it certainly isn't what I meant by 'movie silencers', since they never have this pre-installed on their gun/suppressor in movies.

@newtboy

Well, you can buy silencers and barrels with the system integrated on them, and while the fit is slightly worse than a well-threaded silencer it is nearly airtight. The same basic system is used for high-pressure gas and water commercially so it must provide an airtight fit, even under pressure.

They tested a 3 lug system on the SOCOM pistol, but in the end they went with threads for the final product, but I understand it was a close decision.

I'm not arguing that it doesn't exist, or even work to an extent. I'm just saying it's not what I meant by 'movie silencers' where a simple tube suppressor is screwed to a simple barrel end with a 3/4 twist.
It's neat, but not what I'm talking about.
That said, 'nearly airtight' leaves leaks that allow pressure waves to escape, defeating the purpose of the suppressor to an extent. Also, high pressure water and gas is not the same as explosive pressure waves, I hope this isn't just a modified hose quick connect, the pressures dealt with are on different levels.
The SOCOM pistol example seems to say that, even with the bonus of much faster field installation/removal it wasn't worth the weight or didn't work properly, or both. There's a reason they went with difficult to keep clean and hard to install machine threads.

The Howitzer Taking a Shit sound of movies like Dirty Harry is pretty silly. I guess the "crack" sound all handguns make, some just louder than others, isn't very sexy.

The video is wrong on a few things. Not digging it.

5 minutes on youtube will tell you that Cracked is full of shit...again. Dude puts shower curtain to prevent blood spatter. Silencers do work in a tactical situation, an are used in them.

Automatic rifles can be shot continously for several minutes, most military grade fully automatic rifles are chain fed, so if you got the time, you got the ability to shoot for a long time..and no the barrel won't explode...accuracy goes to shit, but it will still fire. Full automatics are used for supressive fire techniques so accuracy is not crucial anyway. So their premise that fully automatic shooting only takes place in a matter of 4 seconds is bullshit.

You still need to chamber a round...so yes you need to "rack a round" for both pump actions and semiautomatics. and no the bullet dosen't fly out of the first racked round because it gets placed into the chamber.

Basically this whole video is total bullshit, and I think they did it on purpose so people will comment on the utter and complete ignorance of the guy who produced it.

Because if Cracked Magazine is anything, they're scientific!

"So their premise that fully automatic shooting only takes place in a matter of 4 seconds is bullshit. "
Technically the example they gave (the commando reference) it's a clip fed weapon, not belt fed, thus "4 second" example applies. Also, there's a reason why the 249 and M60, 50 cal etc have replaceable barrels, over time the barrel can bend due to high constant rate of fire.

Jesus, gun fanatics get so uptight..

I love Guns!

I'm not discounting the rest of your post but, since we're correcting misconceptions, yes, metal does burn, just very slowly.

In the case of a gun barrel, I would imagine the only realistic threat from heat would be that it would warp and misfire, but I'm only guessing.

(Note, already burning when video starts but I thought I'd throw it out there.)

It looks like its not so much the barrel but the other materials around it, the plastic for the AR, the wood for the AK. The AR towards the end also gets noticeably worse in its full auto performance until finally failing to fire on automatic most likely due to increased friction

Right, fine, and some metal (phosphorous for example) burn really well.

I misspoke, but a gun barrel does not "burst into flames" under any conditions.

Also no mention of subsonic ammunition which makes silenced guns even more silent.
They dont know the different between a machine gun and an assault rifle either.
But to be fair, an AK47 (not a machine gun) can burst into flames. Well kinda at least. The heat will be so big that the wood will catch fire. But not after only a few shots fired as suggest in this video. That will take several hundred bullets to happen, if not over a thousand.

My favorite myth?

You can save yourself from a full-auto assault weapon by taking cover behind a couch!
