  • Patent number: 11105582
    Abstract: An adjustable buttstock has a front part configured to be attached to a firearm, and a rear part forming a prismatic joint with the front part. The prismatic joint has an adjustment axis and allows the rear part to slide relative to the front part along the adjustment axis. The buttstock further has a lock assembly that includes a wedge. The buttstock has a locked state in which the wedge is releasably wedged between the front part and the rear part, preventing a radial play between the front part and the rear part, and an unlocked state in which the wedge is unengaged with respect to the prismatic joint, allowing radial play between the front part and the rear part.

  • Patent number: 9915498
    Abstract: A length adjustable butt pad assembly for a firearm is shown and described. The length adjustable butt pad assembly includes a butt plate having an elongated butt plate shaft and a butt plate base. The butt plate base includes an elongated mounting tube extending in a horizontal direction and receives the butt plate shaft. The elongated butt plate shaft is rotatable in the mounting tube between a first locked position and a second released position. The second released position allows for an axial displacement of the elongated butt plate shaft between at least two fixed locations.

  • Patent number: 8733011
    Abstract: A sight mount for firearms, consisting of a base plate (101), arranged to be fitted onto a firearm. The sight mount is fitted with integrated and split rings and two top ring halves (106, 124) are arranged to attach a riflescope. The sight ring (104, 111) is diagonally split (103) and has planar sides in the vertical and horizontal planes as to make visible the visible the adjustment knobs of the riflescope when in a firing position and to visualize parallel reference lines in the environment, thus providing a sub-conscious perception of the weapons vertical alignment.

  • Patent number: 7730655
    Abstract: A sight mount for fire arms comprises a base part (10) to be mounted on a fire arm, and an upper part (11) to have a sight mounted thereon. The upper part is pivoted relative to the base part for movement about an axis between a first position corresponding to the operative position of the sight, wherein a projection (33) on the, upper part or the base part engages a groove (29) on the other part, and a second position transverse to the first position, wherein the projection is disengaged from the groove to allow the upper part to be separated from the base part. A latch (21) is spring biased to an engaged position preventing pivoting of the upper part, and against the spring bias can be brought into a disengaged position allowing pivoting of the upper part.
