The couple are set to tie the knot at their French estate Miraval later this year and Pitt, 48, has installed the range and an armoury on site as a gift for his bride-to-be, reported Sun online.
"Brad had a lot to live up with his wedding gift considering Angelina exchanged vials of blood with her ex-husband Billy-Bob Thornton.
"But Ange clearly finds shooting an aphrodisiac. When she and Brad were around weapons on the set of 2005's 'Mr & Mrs Smith' they ended up together. And by letting Angelina de-stress at the range, he's less likely to get earache indoors. There's a lot to be said for that when you have six kids," a source said.
