Abstract: A bullet trap is provided comprising a succession of metal sheets slanted alternately forwardly and rearwardly and forming a succession of dihedrons with an angle at the apex less than 60.degree.. The metal sheets are joined together two by two at their front end and are close to each other two by two at their rear end, while being separated by a space forming a passage for the bullets. The upper metal sheets are extended rearwardly, beyond the passage, by a curved portion forming a deflector deflecting the bullets against the rear face of the lower metal sheets.
