I'm just curious if anyone on this forum has seen one similar to this SKS I just got. It's got no bayonet lug and the barrel is 20 inches or so. Markings: Right side of barrel: SK 7.62 CHINA Left side of barrel: CAI ST ALB VT Receiver has what appears to be a triangle but can't tell 'cause previous owner painted over it .:-( The serial # is 22xxxxx and the magazine, bolt and bolt cover have the same last 5 digits as the serial #. Pics.
