Yes, the type 81 sling and the SKS sling are interchangeable. There are so many sling options out there and sources. The cheap Chinese slings are not bad in my opinion, very light, the type 81 and Russian slings are much wider and heavier, I have many but not really my thing. Last I paid was $25 for 2 of those slings with oil bottles and crap shipped on the EE. I sold one to a friend for $20. That's what he wanted to pay, lol.
