I've only got a little time here, but I wanted to debunk a portion of this show. I've never watched an episode on TV, but was shown a link to this episode as "proof" that the AK-47 is more reliable than the AR-15. The important stuff starts at around 27:45 or so.
Well, there are a few glaring problems that a lot of people have probably already figured out.
Here, we see both rifles with mud on their sides. Note the mud on the top cover of the AK and near the rear sight. Click on the images for a bigger picture.
And here is the AK as we hear shots being fired. The safety is clearly in the "up" position - the weapon cannot be fired that way. If the safety was off, there'd be a void where the mud hadn't stuck to the rifle, as we can see from the video, the safety was on when it was slapped with mud. No spent cases are ejected. The bolt does not move. He is not wearing ear protection.
Here is the weapon actually being fired - note the complete lack of mud on the top cover and rear sight. The weapon is never shown from the right side with cases being ejected.
As the "muj" comes off the firing line, we see that his shirt and face are perfectly clean - as anyone who's fired a muddy weapon with an open reciprocating bolt like an AK-47 or a Garand knows, that mud will come right back at you.
And finally, here we see him wearing orange earplugs, supposedly just as he's finished firing.
Here is the AR as we hear shots ring out. No cases are ejected, the ejection port cover does not swing open, and we don't see any steam from the muzzle, as one would expect if the barrel was wet.
More shots being fired. Ejection port cover still closed. In case you don't know, that means the weapon still hasn't been fired.
And finally, we see the AR-15 after it "jams" - except that the ejection port cover is STILL closed, and the only way to verify a malfunction is to look through that open ejection port cover.
In conclusion, this test was a complete farce, as is, I assume, the rest of the show. I assume that the impacts we see are just squibs being controlled by the guy on the computer.
