I'm just saying the AK-47's not a bad way to go for a battle rifle. It's the most popular platform in the world for a reason and can easily hold its own with an M4/AR-15 based rifle. As it sounds you know more about it than I do. Just saying...
I would almost agree with you in an urban setting. With very close distances. It is a bigger caliber, and has auto. M4's have 3 round burst, which is really all you need. One you go past that, its rarely accurate. However, once you start adding distance between the two parties firing at each other, the AK sucks. At least the ones the Taliban are using. I have my own, and keep it clean. Its very accurate shooting single shot. Mine is not full auto. I have shot one that is, and there no way you can be even close to accurate in anything but a 3-4 shot burst, and at close range. You cant just hold the trigger down and hope to be accurate.
The AK is an amazing weapon for what it is. You can abuse the crap out of it, and it will still fire. And its cheap. So in that respect its great. But I do not
personally believe it is the best assault rifle.
This is me in Afghan last year with an AK we took;
We played around with them, was fun. On one operation, we were getting shot at a lot. It was my job to clear a hill (combat engineer) from IED's. I kept getting shot at, and so i stopped and waited till they stopped. Went back to clearing, and they shot again. Played that cat and mouse game long enough, and I just kept clearing because they werent that close to hitting me. They were about 300 meters away in a tree line, but we couldnt see them with our 4x optics. Shot back a bit when we saw them shoot, cause you could see them then. But theyd just move. Anyways, as I said they werent that close. A few got within 5 meters or so, but thats it. So I just kept clearing. Then we got our MK-19 and snipers up there, and fun was had.
I guarantee if the tables were turned, we would have picked them off. I was sky-lining my self big time, but they couldnt hit me with that weapon from that distance. Im not trying to come off like a know it all, because I dont know it all. So please dont take it that way. Ive just had some experience with the AK's that the taliban are using. And the A4 that I used. I would much rather have my A4.
