The model 70 has a small button on the left side of the bolt. The one I had split and fell off. The rifle was inoperable. The Sako I bought in the mid 70s and I used it for several years. About 3300 rounds I was shooting prairie dogs with it and the bolt wouldn't open. I fooled with it for several months, finally sold it to a friend who had it for another 6 months. One morning he picked it up, turned it over and heard a click. The bolt opened. Found a small spring in the action had broken and locked up the action. I am glad both of these happened at the bench or close to home and not on a expensive trip.
