I bought my Zastava M85 in 2016. At that time there were plenty M85s in Canada. I don't quite buy that argument with military contracts. Serbia is not involved in any way with supplying arms to Ukraine.
Regarding a Sabatti, I bought a Sabatti Rover 600 in 2019 from Marstar. They were on sale for a very good price. Nowadays, the Sabattis are completely gone from the Canadian market. Similarly to the Zastavas. There are some other reasons for this happening.
This way or the other, since I don't hunt anymore, I donated both the M85 and Rover 600 to my son-in-law. He is now a hunter for the entire family.
