Abstract: A device comprised of bubble level inserted into and secured within a cavity located above the rifle grip and behind the barrel to facilitate the measurement and compensation of the rifle's cant while lining up the rifle's sights. The device is precision machined to allow the bubble to be aligned with the axis of the barrel to produce a true “zero-cant” condition. Graduation markings are placed on either left or right of the bubble level to allow the user to better judge the relative degree of cant. A light source is placed adjacent to the bubble level to illuminate cant for a shooter in a dark environment. Methods of using the embedded cant indicator for precision shooting are presented.

Abstract: To reduce the mass of a sabot having a pull and a push function, it is proposed that the sabot comprise mutually separate sabot parts, wherein at least one sabot part is configured such that it performs the pull function and at least one sabot part is configured such that it performs the push function. The sabot parts are nested. This can be implemented in the form of cylindrical nesting or in the form of tangential nesting. In the case of the cylindrical nesting, the outer sabot part encloses the inner sabot part along an interface. In the case of the tangential nesting, the sabot parts are divided into sabot subsegments. The latter are nested in alternating fashion in the tangential direction such that a pull-sabot subsegment and a push-sabot subsegment are nested in alternating fashion in the circumferential direction. To provide sufficient sealing, the sabot subsegments overlap one another.

Abstract: A turret display device is used for rapidly zeroing a riflescope. The turrets on an improved riflescope provide a turret position signal. A display of the turret display device comprises turret display cross hairs displayed relative to a target icon. When the turret display device receives a turret position signal, turret display cross hairs move to show the relative movement as indicated by the received turret position signal. When a distance is processed by the turret display device, the turret display cross hairs move to show an aiming point relative to a target icon based on the current zero of the riflescope. The user zeroes the riflescope to any distance by turning the turrets until the turret display cross hairs are centered for the desired distance. In some embodiments the turret display device is integrated into a hand held rangefinder, smart phone, or riflescope. A riflescope having turrets which each provide a turret position signal.
