RIGHT. I bought one new in 1970, and have owned several since.

Not sure which year they changed, but think it was 1984 (that is when the manual changed), they changed the triggers slightly. The early production M77 had a fairly easy to adjust trigger, and a small access hole was in the trigger guard so you could get to the trigger pressure set screw. Up until 1984, the owners manual had a picture of the trigger assembly, and the correct Allen key came in the box.

After the change the hole was gone, the post 1984 manuals don't have the picture of the trigger assembly. And a tighter set screw for the trigger travel was installed at the factory. You can tell if a M77 has the changed set screw by looking on the action under the bolt handle those with the stiffer screw have a T stamped under the bolt handle. If you have a rifle with out the stamping Ruger will send you a new one, with installation and adjustment instructions.

I believe these rifles have a 771- prefix in their serial numbers.
