  • MODULAR SCOPE MOUNTING SYSTEM WITH SERRATED INTERFACES FOR MOUNTING COMPONENTS
    Publication number: 20240093967
    Abstract: Firearms and accessories are disclosed herein. The firearm can carry a scope mounting assembly configured to couple to a firearm and includes serrated interfaces configured to engage a complementary serrated interface of a component such that the component is rotationally and translationally fixed to the scope mounting assembly. The interlocked serrated interface maintains positional relationships between the component and another component, such as a scope, and/or the firearm.

  • FIREARM BARREL PRE-LOADING DEVICES, CONNECTION ASSEMBLIES, AND FIREARMS
    Publication number: 20210341249
    Abstract: A firearm barrel preloading device can preload threaded connections. The preloading device can include an outwardly facing barrel-contact surface, an outwardly facing receiver-contact surface, non-planar surfaces between the barrel-contact surface and the receiver-contact surface. The non-planar surfaces can include mated pairs of axisymmetric surfaces that cooperate to spread apart the barrel-contact surface and the receiver-contact surface when the preloading device is moved toward an expanded configuration.

  • Bolt mechanisms and firearms containing the same
    Patent number: 10458733
    Abstract: A firearm includes a bolt mechanism with a bolt configured to receive a firing pin assembly and a bolt head assembly. The bolt head assembly includes a pivoting bolt head and an extractor. The extractor is positioned relative to the bolt such that substantially all forces applied by the extractor to the bolt mechanism are reacted within the bolt head assembly. A biasing member or element can urge a claw portion of extractor towards a distal end of the bolt head.

  • Multi-caliber firearms, bolt mechanisms, bolt lugs, and methods of using the same
    Patent number: 10082356
    Abstract: Firearms with bolt mechanisms, ambidextrous functionality, and/or isolated receivers are disclosed herein. A multi-caliber ambidextrous firearm can have a receiver and a bolt mechanism with a bolt that seats against one or more load bearing surfaces of the receiver. The load bearing surfaces can be configured to maintain proper contact before, during, and/or after a firing event. A bolt head of the bolt mechanism can be replaced to use the bolt mechanism with different cartridges.
