The present invention is an adjustable-length stock for a shoulder fired weapon, which preferably includes an extendible shoulder piece installed on a shortened gun stock. The extendible shoulder piece preferably includes a butt plate for placement against the shoulder of a user, and a telescoping connection between the butt plate and the shortened gun stock. The connection may have at least one support rod and preferably two support rods telescopically sliding within their respective support tubes. After adjustment, the stock is locked at the selected length, thereby fixedly holding a desired length. The preferred two connections between the butt plate and the gun stock are vertically-distanced as much as possible, in order to stabilize the butt plate. The system preferably also uses a bipod for forward support of the weapon while being used by the adolescent. This system may be used to teach adolescents how to fire such a weapon.

The dry shaving apparatus as claimed in claim 4, wherein the inner surface (36, 37) of the housing part is formed on an end wall (13, 14). 6. The dry shaving apparatus as claimed in claim 1, wherein the position-force component (FS) is directed in a single direction parallel a direction of oscillation of the cutter element. 7. The dry shaving apparatus as claimed in claim 1, wherein the holding-force component (FU) acts in opposition to a direction of withdrawal of the removable fire from the housing part. 8. The dry shaving apparatus as claimed in claim 1, wherein two seating surfaces (20, 21) are provided on each longitudinal side wall (53, 54) of the removable frame. 9. The dry shaving apparatus as claimed in claim 1, wherein, relative a common origin of mutually orthogonal x-, y-, and z-axes, each of the seating surfaces of the frame extends at an inclination to the x-axis and at an inclination to the y-axis as projected onto a vertical plane and at an inclination to the z-axis projected out of said vertical plane. 10. The dry shaving apparatus as claimed in claim 1, further comprising a stop surface formed on an inner surface of the housing part, and wherein the seating surfaces (20, 21) of the removable frame are provided on longitudinal side walls (53, 54) of the removable frame, and the seating surfaces of the removable frame are constructed to ascend in the coordinate axes x and y as well as x- and z-axes relative to a common x-, y-, z-axes origin towards the stop surface. 11. The dry shaving apparatus as claimed in claim 1, wherein two said detent seating surfaces (80, 90) are provided on each said detent element (18, 19). 12. The dry shaving apparatus as claimed in claim 1, wherein an alignment of the detent seating surfaces (80, 90) on the detent elements (18, 19) is adapted to an alignment of the seating surfaces (20, 21) on the removable frame. 13. The dry shaving apparatus as claimed in claim 12, wherein the detent seating surfaces (80, 90) of the detent elements (18, 19) engage the seating surfaces (20, 21) of the removable frame (WR) along an approximate contact line (100). 14. The dry shaving apparatus as claimed in claim 12, wherein an engagement of the detent seating surfaces (80, 90) of the detent elements (18, 19) with the seating surfaces (20, 21) of the removable frame is approximately point-type contact. 15. The dry shaving apparatus as claimed in claim 1, wherein the detent elements (18, 19) arranged in the housing part are adapted to be acted upon by a coil spring element (52). 16. The dry shaving apparatus as claimed in claim 1, wherein a spring element (52) biases two said detent elements (18, 19) in opposite di
