A portable gun support case having gun support members firmly held in place on the case by retaining members attached to the case. The case has a lower box and an upper box which includes two longitudinal box or cover sections pivotally mounted on the lower box. When the box is open, the support members may be placed in upright positions adjacent walls of the lower box. The retaining members then may be moved into firm holding engagement with the support members. When the support members are removed from their upright positions, the upper box may be pivotally closed above the lower box along a center line formed by the two longitudinal cover sections and in engagement with the lower box. When the upper box engages the lower box, outward projections at opposite ends of the upper box are engaged by the retaining members to hold the case firmly closed.
