Nigel Murray, Dan Bentley, David Smith and Zoe Robinson lost 18-1 to Thailand on Monday but they bounced back to beat Portugal 7-5, despite needing the judge’s measuring tape on several occasions.
They took two points in the second end after two balls were judged to be marginally closer to the jack and built a 5-1 by the half-way mark in similar fashion.
Portugal got four points back in the fifth by throwing the jack to the back of the court and watching GB fail to make the distance but the home quartet held their nerve to complete victory.
“It was great to bounce back from a heavy defeat. The Thailand guys took us apart in the semis and even if we were at our best, they would have probably still beaten us,” said Smith, who lives in Swansea.
“We had a slight squeaky-bum moment at the end of the fifth set when we left it a bit open. We would usually nail them, which was a bit strange, but I’m happy we saw it out.”
The Games will be captain Nigel Murray’s last and Bentley said: “He has gone out on a high. I wanted a medal for myself but partly to send him off on a high note.”
The Chelmsford player added: “The team were excellent. We have done it many times before but to do it today was excellent.”
Scotland’s McGuire brothers, Peter and Stephen, missed out on a podium place in the BC4 Pairs after their second loss of the tournament to Canada, this time 8-2.
Peter was hospitalised with a chest infection on Sunday evening and was only back in the Paralympic Village for an hour before leaving to take part in Monday’s semi-final defeat to favourites Brazil.
“To be honest, with what has happened over the last 36 hours we are just glad to be here,” said Stephen. “It may have affected our performance but we are not making any excuses.”
Peter added: “I’m aching all over but I’m just glad to be back playing. I’ve got the Individual event to go for now and that’s what I’ve got to focus on.”
All six of the GB players who played in bronze-medal matches return to action on Wednesday when the Individual tournaments get underway.
