Look at it...it takes duck bill mags, that's not an actual mag well. That stock looks like it would still accept the original built-in magazine...it's an SKS still, of course it's cheaper than a type 81, but drop an SKS in that stock in today's market, and you're out $600+ and you still need to buy mags. You still can't change the mag with one hand, and you still can't insert a mag on a closed bolt without modification...I'll take a type 81, I already have 2 original SKS's...I would mod one of my SKS, only if the trigger could be moved, and had a proper mag release...
