Yeah, but the AK shooter was jerking that trigger, which is hardly conducive to accurate shooting. And, on top of that, the show failed to point out it is easier to adjust for distance with the AK than the AR's A1 sights.
That said, of course nobody would argue that the AK was more accurate than the AR. It most certainly is not. However, the piece had some bias in its demonstration that could have affected the on-paper accuracy (not to mention the AR slow motion video does not show the muzzle's motion, which also has some flip, which exaggerates the AK and minimizes the AR). It would have been better to have the same guy use both rifles, but that could bias towards what he is accustomed shooting. In any case, seeing a guy jerk a trigger like that doesn't make me think he is all that good with an AK.
I also have a problem with the cants of wood, the 4x4's connected together. They called that dense pine, but that is entirely false. Those are cores of the pine, which contains the only portion of juvenile wood in the tree. The juvenile wood is less dense with less structural strength than any other portion of the tree. The center of those cants are not all that dense. This doesn't matter in construction which is why these are core-cut in the first place. Like the human bone, having a soft center in a 4x4 does not make it weak, the less dense center is just fine. You'd rather have the juvenile wood in the center than on an edge. The edges are denser, of course, but that ain't 8 inches of dense pine, it ain't even 8 inches. 4x4's are actually 3 1/2 inches wide, not 4 inches wide. Put them together and you get, yep, 7 inches not 8 inches.
