Serial number and features
No, the barrel from a Remington 700 will not work on a Remington 7600. The two rifles have different designs, action types, and mounting systems, making their barrels incompatible. The Remington 700 is a bolt-action rifle, while the Remington 7600 is a pump-action rifle, which further contributes to the differences in barrel configuration.

No mate. 7600's first came out in the early 80's, 1981 I believe. Prior to that was the model 760, which is like the older sister of the 7600 and was first catalogued around 1952 I believe. Remington made pump rifles in different models way back to about the time of WWI.
Remington discontinued the Model 760 rifle at the end of 1982 and introduced the Model 7600, Model 76 (cheaper version) in 1983. Yes, it is still being made.
