AK-47 Underwater at 27,450 fps

[Feuer Frei!]

Now this is cool, the video is 10 minutes long, well worth watching imo.

Destin uses an AK-47 to teach you the Physics of cavitation

I approve of this science.:up: That's wicked cool.

That's exactly how a depth charge causes its damage. It's not the explosion, it's the implosion that pulls at the hull of the boat, flexing and straining the metal, and that's really what causes the damage. Excellent video! I love science experiments :rock:

You can see how some of the gases pass through the ports on the gas tube.That is actually the most important part of an AK if that tube where to get dented deep enough to effect the piston you pretty much have a 30 round bolt action.

Of course it also shows why the AK-47 is so reliable plenty of tolerance so it get get pretty darn dirty and still produce enough force to move the bolt.

I saw some place a laboratory grade slow motion video of an AK-47 and an M-16A1 firing it was very interesting to see the difference between the two.The rifles where places in a rig so that only the weapons movement would show and you could see the entire rifle.

The AK move a lot but this makes sense because it was designed to be as reliable as possible so it has loose tolerances which of course means that dirt and grime can build up at not foul the operation as easily.The M-16 on the other hand had very little movement which again makes sense as the M16 was designed to much closer tolerances which generally increases accuracy.


I found fairly decent clip of an AK-47
https://www.youtube.com/watch?v=55Rt3l5CZKI

And an AR15 this company is promoting the smoothness of its triggers so they do not show the barrel but the barrel on any gun will flex to some extent upon the projectile travel with an AR15 or any sibling it will flex much less than the AK47 barrel flexes.Keep in mind also that is this clip the rifle appears to be braced and the AK47 is not also single round being fired vs multiple for the AK.They did not use a larger magazine in this clip(looks like they simple chambered a round as even a 5 rounder is not fully flush which is a slight bit unfair as you'll see more movement due to the cycling so in all honesty this video is a bit sneaky.

Which one? That one does not attract everyone though a bit niche it only attracts people who are a bit more knowledgeable and actually own firearms.


Anyway here is a protip.If you have never fired an AK before do not hold the thing by the magazine while firing chances are that you did not seat the magazine well and it will pull up a round and send the magazine and your hand flying downwards with pretty good force.Seen a few people do this(not with my property) which is why for a layman I choose to load an AK myself and tell the person not to hold it by the magazine lest they wish to discover the capital of Thailand.I think much of that has to do with cheapo AK clones and cheapo magazines though by design holding an AK by the magazine while firing should not be a problem so it is either a crap gun or a crap magazine in most cases or a very timid loader.

If the magazine is properly seated in the well it should not come undone. Have you seen the mag release on that thing? It's a huge steel tab with a fat spring behind it. You know when she cracks home that she's locked in. The AK is like a Biker chick, you gotta slap her around a little to get her to perform.

The M16 on the other hand is like a snooty redheaded prom queen, you look at her funny and she'll jam up on you and leave you hangin, but if you care for her she'll do the job cleaner and better than the biker chick. :03:

Sure I own two but the cheapo magazines barely fit correctly(I do not use them personally).A friend of mine got a couple of mags from his dad for an AK74 (Romanian I believe) and they fit like crap even with the magazine catch latching he tired one dry just see how it looked loaded with rounds and felt that they where unsafe and would fly out.

Another friend had a Misr and used a traditional metal 30 rounder it clicked and all but after he fired maybe 4 or 5 rounds the magazine just popped right out it had to have been something with the magazine as far as I am aware the rifle itself was just fine.

I have seen people at public ranges have mags fly so I always assumed that they did not seat them correctly only way they could come out unless either the magazine was really bad or the rifle had a jacked up well or catch. In these cases I only observed and did not know the experience level nor quality of the firearm.

All that is why with my own firearms if a lay person wants to shoot one I load it my self I'll show them how to do it if they want to try the entire process.

In my experience honestly the M16 is the one people are overly timid with if you do not solidly seat an M16 magazine you'll have problems.I recall back in USAF basic on the range they gave us maybe a 4 or 5 hour course on the operation of course some guys like me where already very familiar.On the range though all the newbies the most common thing was they failed to seat the magazine well enough being too timid.I just hoped that I never had to be in a real hairy situation with this guy here who cant even properly load his weapon.I like the way the Marines think every Marine is a rifleman.

If you're going to get an AK variant, the WASR10 Romanian is about as close as she comes to the real Kalashnikov. Only use cold rolled steel mags (man mags), because you can beat down an attacker with just a fully loaded magazine! The issue lies in people skimping out and getting all these frilly polymer jobs. If you're going to use a polymer mag, then a polymer design AK variant like the Saiga 7.62x39mm would be the best fit. If you want to use polymer in the real deal steel versions, you have to file down the top of the catch tab on the mags in order to get that latch to fully seat.

The main issue is that people try to mix and match, and like the touchy feely society we've become, we're all too worried we're gonna break a nail while man-handling these things. They're combat rifles! Slap that mag in there like you got a pair! You're not gonna hurt its feelings! I used to beat on my WASR10 like the biker chick that it was, and it NEVER malfunctioned, not ever! As soon as you start limp-wristing it, IT will own YOU. You must make IT your <expletive>. You get the point :03:

P.S. I served as Army Infantry for 4 years. The first thing they teach you is "toughen up, otherwise this weapon is going to kick your......"

[Wolferz]

That was more than a ten round clip he had on that weapon.:huh: I'm sure he'll get a visit from the bleeding heart goombahs.:hmmm:

My M-16 in basic was manufactured by the Hydramatic division of General Motors.:up: It was a good weapon that only jammed once, due to crummy blank ammo. Most of the other troopies got Colts and had all manner of problems. Like one idiot who got a cleaning rod stuck in the barrel and just left it there. Then he took it to a range and fired it.:-? Pop no kick and you get dragged out of a foxhole by your helmet. CLEAR THE RANGE!

I have fired a Chinese made AK-47 and I didn't really care for it. Except the fact that it would put a round through a tree. 7.62 baby!

[gi_dan2987]

I hate being a nomenclature Nazi, but I cringe every time I hear the term "clip" when referring to a "magazine." Clips hold a set of rounds for which to load mags. Mags are self-contained, self-feeding ammunition containers that are loaded by clips to load firearms. Sorry, I had to. I just like to clear up confusion is all :D

I stand corrected.:D Clips are those little doodads that hold belt ammo together for crew served weapons like the M-60.:rock:

That video would have been cooler if he used one of those.

Not so. The initial explosion creates a shock wave that causes immense pressure against the hull (the same as a torpedo). It does also create a gas bubble which then collapses, which causes a secondary shock wave that can cause even more damage.

That Evelyn Woodhead sped reedin course have done come in real handy.:O:

Back to the AK-47... BANG switch on. BOOM!

You're correct Steve. It's the pressure wave that causes the damage, along with the reverberating shock waves. If you ever stand close to a lightning strike, you'll get the picture first hand.

I heard they can be good but some can be less so of course they tend to go for less than other AKs.I have two pre-ban (1988 ban) Norinco 56S Chinese made pretty much a semi-auto only type 56 never had any real problems with them but of course I bought them from a very reliable dealer who is friends with my father this guy does the whole lot Class 3 and all he has Lewis guns WWII SMGs but you have to deal with all that paper work and tax stamps plus those things are not cheap.I do not use the polymers myself.I am much more a fan of the Mosin-Nagant M9130 though I have a nice little collection of those and with one of those you can hit something well past both 7.62x39 and 5.56x45 ranges and actually have some effect.

Could have just been a lousy one or perhaps someone built it themselves from parts in which case it could be utter crap or quite nice.Same goes even with the US "made" they are all in fact combinations of foreign and Us made parts and assembled in the US.Sometimes the foreign parts are new other times surplus which most likely explains how most makers will have an occasional lemon.Still in most cases lemon firearms are usually ones built form parts by a private individual who has no gunsmithing skills.
