Patent attributes
A firearm butt stock with an adjustable cheek piece comprises an elongate stock base having a top, a bottom, a right side, a left side, a proximal end and a distal end. The stock base has a transverse pivot shaft near the stock base top and a transverse catch shaft spaced from the pivot shaft lengthwise of the stock base near the stock base top. A cheek piece has a proximal end and a distal end and a left and a right sidewall. The cheek piece defines a plurality of lengthwise stacked receptacles opening toward a proximal end of the cheek piece and an elongate hole having a distal and a proximal end spaced lengthwise and distal of the stacked receptacles. The stacked receptacles, the catch shaft, the elongate hole and the pivot shaft are configured so that with the pivot shaft received in the elongate hole and the pivot shaft at the distal end of the elongate hole, the catch shaft is received in one of the stacked receptacles and the cheek piece is prevented from pivoting about the pivot shaft. With the pivot shaft at the proximal end of the elongate hole, the catch shaft clears the opening of the stacked receptacles and the cheek piece can pivot about the pivot shaft. A spring detent is provided in operative association with one of the pivot shaft and the catch shaft. The spring detent prevents relative movement of the pivot shaft and the proximal and distal ends of the elongate hole without application of a lengthwise force to the cheek piece in a desired lengthwise direction of movement sufficient to overcome the spring detent.
