Anyone into the SKS? I have 3, one Yogu and 2 Chinese. My YUGO. 7.62X39, grenade launcher on end of a 20" barrel, grenade launcher flip up sight, night flip up sights. All the numbers match on the receiver, trigger group, bolt & carrier and 10 round fixed mag. this gun was made in 1978 and was never refurbished or re-stocked. It is in very good condition and when I got it, it was covered inside & out with cosomoline.
