Ruger M77 Mark II Complete Specs and Full Gun Specifications

The major changes to the M77 that were made to create the M77 Mark II were to the safety, trigger and bolt. The original two-tang safety has been replaced by a three-position mechanism which allows the chamber to be loaded and unloaded while the bolt can move (as well as locking it in position to prevent it moving all together). The original trigger has also been replaced, with a two-stage trigger designed to remove large amounts of movement and weight in the trigger to make firing easier.
