It is basically an economy Model 700. So anything that will fit a 700 will fit the Sportsman 78.
If you want to get rid of it let me know.

I have owned one for 30 years and it is a tack-driver!!! I put a lone wolf stock on it and have a Ziess 2.5x-10X52MM Scope on it. It is light, accurate and all the gun I need for anything in NA.
