US Army sergeant Vincent Hancock on Tuesday retained his Olympic title in the men's skeet.
The 23-year-old from Columbus, Georgia, added the gold medal at London 2012 to the one he won four years ago at Beijing, becoming the first skeet shooter to win back-to-back titles.
Hancock also broke his own Olympic record, missing just two shots and firing a perfect 25 in the final, to register 148 points in the discipline which sees competitors fire at clay targets from seven different positions on the range.
Hancock finished two points ahead of Denmark's Anders Golding, who took silver.
Nasser Al-Attiya of Qatar won the bronze after a shoot-off with Russia's Valeriy Shomin, who had to be content with fourth on his 41st birthday.
