Patent number: 11927407Abstract: A safety selector for a firearm, including a first lever including an integrally formed safety shaft and a first handle located outside the lower receiver for actuation, as well as a bearing portion, a selector portion and a connecting portion. To facilitate disassembly and interchangeability, the first lever is configured for spring-biased coupling to a securing element and has, on the connecting portion, a positioning protrusion projecting toward the opposite side of the weapon. In a longitudinal direction, the positioning protrusion has a shape-complementary bore for receiving a connecting assembly which includes a connecting element, a spring and a spring lock.Type: GrantFiled: December 14, 2021Date of Patent: March 12, 2024Assignee: GLOCK TECHNOLOGY GMBHInventors: Mario Kastrun, Patrick Nolte, Karl Markut

Patent number: 11796267Abstract: Rifles having a weapon median plane, with a barrel with a barrel bore axis, a gas drive, a sliding block, a closing spring unit, and a charging handle assembly arranged in front of the sliding block, where the charging handle has two operating handles pivotally mounted about pivot pins on a slider body, said operating handles being pushed about the pivot pins into their rest position by at least one handle spring. For facilitating the use and especially the forward shift of the charging handle, the slider body is mounted on a carriage which is arranged axially in front of the sliding block and movable in the axial direction.Type: GrantFiled: September 29, 2020Date of Patent: October 24, 2023Assignee: GLOCK TECHNOLOGY GMBHInventors: Mario Kastrun, Elmar Bilgeri

Patent number: 11761720Abstract: A rifle having a central weapon plane, comprising a barrel that has a barrel bore axis, a gas drive, a bolt carrier, a recoil spring unit and a charging handle unit arranged in front of the bolt carrier, wherein the charging handle unit comprises at least one handle, which is mounted on a slider element for rotation about pivot pins and is forcibly displaced about a pivot pin into its rest position by at least one handle spring, and the slider element is mounted in a carriage which is arranged axially in front of the bolt carrier and is movable in the axial direction. The rifle is characterized in that the at least one handle comprises an elongate hole for receiving the pivot pins and for the support by said pins.Type: GrantFiled: September 30, 2020Date of Patent: September 19, 2023Assignee: GLOCK TECHNOLOGY GMBHInventor: Mario Kastrun

Patent number: 11662164Abstract: Magazine holders for firearms, including two actuating elements and a spring, where the first actuating element-has a locking extension for the temporary attachment of a magazine and a first actuating extension, the second actuating element has a second actuating extension, and where the two actuating elements are (operatively) connected to one another such that the locking extension releases the fastening of the magazine counter to the tension of the spring during a release movement onto one of the two actuating elements. Each actuating element is designed as one piece, in that the second actuating element has a bearing extension on an end section facing away form the second actuating extension and connected by a connecting section, and the first actuating element has a substantially shape-complementary bearing opening for receiving the bearing extension in an assembling position.Type: GrantFiled: September 25, 2020Date of Patent: May 30, 2023Assignee: GLOCK TECHNOLOGY GMBHInventor: Mario Kastrun

Patent number: 11320221Abstract: Firearms including magazine holders operable from either side of the firearm. The magazine holder includes two interconnected actuating elements, pivotable with respect to one another and separable from one another by longitudinal shifting, and a spring. The magazine holder is configured so that when pressure is applied to a right actuating element, a moment of force is applied to a first actuating element, which it cannot follow, and so both actuating elements, without changing their relative position to one another, are shifted against the force of the spring normal to the weapon median plane, removing a locking extension from the magazine housing. Upon actuation of the left actuating element, a stop on the right actuating element prevents its shift transverse to the weapon median plane, and so the first actuating element pivots against the force of the spring, and the locking extension is again moved from the locking element.Type: GrantFiled: October 2, 2020Date of Patent: May 3, 2022Assignee: GLOCK TECHNOLOGY GMBHInventor: Mario Kastrun
