The American crossbow performer is one of 45 acts through to the semi-finals and will be one of the first lot to perform this evening.
Back in the auditions, Ben got Simon Cowell involved in his act but this time it will be himself in the firing line.
"It is the most dangerous thing I’ve ever done in my career," he teased. "I am scared because I’ve turned the tables and will go in front of the arrows myself.
“I’m risking my own life. You just have to balls up and do it. I can’t think about it, I just have to do it."
Speaking to the Daily Star on Sunday newspaper, Ben revealed: “I have had a few meetings with BGT over my act.
"They are worried about the level of danger and are of course very concerned.”
If Ben gets through to the final in this evening's public vote - and of course doesn't kill himself - he hopes to get Alesha Dixon on stage for his next performance.
"If I can get through to the final I would love to use a judge in my act again," he said. “I used Simon (Cowell) in my audition, so I wouldn’t want to tempt fate a second time.
"But I would love to do something with Alesha.
"She is gorgeous and would be perfect. She’s definitely got the look of someone I would want to go after. But it could be risky.”
Alongside Ben, acts performing tonight include Alesha Dixon's golden buzzer act 100 Voices of Gospel, singer Kathleen Jenkins and impressionist Darren Altman.
Joining them are singing mum and son Mel & Jamie, gymnasts Spartans Resurrection, dance troupe Total TXS and ballroom performers Ystrad Fawr Dancers.
