The Mixed 50 metre rifle three positions event was a shooting sports event held as part of the Shooting at the 1976 Summer Olympics programme.

The competition was held on 21 July 1976 at the shooting ranges in Montreal.

Bassham suggested that two gold medals be given, and after this request was declined, asked Murdock to share the top step with him at the award ceremony.

Women had no separate shooting events at the time and were allowed to compete with men.

Murdock became the first woman to win an Olympic medal in shooting.
