Many excellent components came in with the Turk importations, apparently they possessed a lot of these desirable spare parts. I use to buy these old Turked G98's and part then out for the best parts (cleaning rods were the big thing. I'd buy a rifle just to get the rod, - a good rod is worth $50!), - some great stuff surfaced, especially bolt components.
None of this harms their value or desirably, these are always the most desirable parts you can find. Especially the FP, - though a real deal BL sure can be handy when you have a DC missing its foreend!
