I picked one up yesterday at the Timonium Md. show, VG Samco for $179.99 OTD. I once owned a Chinese SKS and was familiar with that rifle. Unfortunately had to part with it 9 years ago. The Yugo appears to be a slightly different animal. I see this little knob on the end of the gas tube that can be changed into different positions. Has somehing to do with the grenade launcher, I think, channeling gas or something. Could someone explain this? Also, is there a way to get a date on these? Thanks.
