Abstract: A portable bullet trap device for catching bullets fired at the device comprising a box having a bottom, a top, and front, back, and opposing sides. The front has an opening for the passage of bullets fired at the device. A plurality of vertically oriented resilient panels are provided in the box aligned with the opening in the front. The panels are spaced from each other to form spaces between the central portions of the panels through which spent bullets can fall if they cannot penetrate the next successive panel. The panels may be provided as a replaceable cell having spacers between the marginal edges of the panels. Alternatively, the panels may be separately mounted in slots in the opposing sides of the box. A target means is provided to spread shots over the panels.
