Cost, revenue, availability, demand and market capacity. Easier to sell locally or in Europe, where collectors could enjoy original full auto, converted semi auto, full auto blank firing for reenactors, or decent deactivation when you can take down all parts and it cocks and clicks. For original semi autos European collectors would also pay more. All we get are refurb bolt actions and semis as it's bottom cheap and perfectly fits into our castrated gun privileges. Even with bottom cheap category - how many more Skss could this market swallow? Not much I think. Even I have one SKS and everytime I bump into it I am asking myself why do I need it? Of course it's nonrefurbed all matching scarce letter series rifle, but still I dont need it nad I have it. I think we have more SKSs than the number of PAL holders.
