Provided is a crossbow riser that may comprise a plurality of cells defined by walls. The walls may consist essentially of a material wherein the yield tensile strength at 0.2% strain is greater than 780 MPa, and either the specific strength is greater than 200 kN·m/kg, or the density is less than 6.0 g/cc. The cells may collectively define a first volume. The walls may collectively define a second volume. The ratio of the first volume to the second volume may be greater than 1.5.
