Regarding the one listed:

Only one year of production-1979. Stock and forearm the same as the 7600 which was yet to be introduced. New style rear sight. Screw hole spacing still the same as the 760.

Only 11,932 were produced.

I have several of these in 35Rem, one rechambered to 358Win and cut to 19".
