Many of you think the canvas type slings that are for SKS are the same as AK. But it is not. SKS sling is slightly thinner than AK sling and , also front clip is reversed, see picture:
Heavier duty M70 sling is also used on M72, M76 and M84. I just got a package of 100 of these from Serbia. Am thinking of selling some for $25 each but am not shure yet.
