Winchester or FN tactical in 7.62x39 never heard anything more about it. This was awhile ago. Its was a CRPF. green stock later style bolt. the round type, NOT Mauserhttp://www.zastava-arms.rs/
also this M85 in 7.62x39 is not really a Mauser controll round feed either. When closing the bolt you can feel the extractor go over the rim. Its the same extractor type on my 1891 Argentine Mauser , design to go up and over the rim of cartridge.
What look like a Mauser extractor is just a guide on this M85.
I need to shoot it and see maybe lapping it will help.
Between this and the Auto Ordance Paratrooper M1 Carbine(jam amatic) I am very dissapointed In my gun buying decisions. I really need to read the forums alot more before buying on looks and impulse
