Larry Godfrey, Simon Terry, Amy Oliver and Naomi Folkard all impressed on the final day of Team GB's extensive selection process at Lilleshall.
The names of the six archers who will represent Britain in London will be confirmed at Lord's on May 9, with Alan Wills and five-time Olympian Alison Williamson expected to be in the mix for the men's and women's team.
After three intense weekends of head-to-head competition, which started with 17 hopefuls vying for six spots, two-time Olympian Godfrey topped the men's standings with a score of 6518.40.
Terry, who took double bronze in the Barcelona Games as an 18-year-old, took second place with 6485.40.
Wills was the man to take third place ahead of a spirited Michael Peart.
Rotherham archer Oliver confirmed herself as the top medal prospect in the women's ranks, heading the scores with 6167.60, while Folkard shot consistently to spring something of a surprise by edging Williamson for second with 6130.67.
It would nevertheless be a huge surprise if Williamson, who was Britain's highest-ranked female archer at the end of 2011, did not win a place ahead of fellow hopeful Charlotte Burgess.
"We've had three days of outstanding archery from eight very talented archers, and they can all be very proud of themselves," said performance director Sara Symington.
