  • Patent number: 8943866
    Abstract: A magazine lock for a firearm includes a magazine well and a magazine latch. The lock includes a tube nut positioned within a housing. The tube nut is connected to the magazine latch of the firearm. When tightened down, the tube nut prevents the magazine latch from releasing a magazine from the magazine well. A tool is provided to engage the tube nut and rotate the tube nut within the housing permitting the magazine latch to release the magazine. The housing includes a biased engagement feature that selectively prevents the rotation of the tube nut within the housing. The tool is configured to overcome the biased engagement feature and to engage the tube nut so that rotation of the tool rotates the tube nut. A breech block inserted into the top of a magazine inserted into the firearm may also be used to lock the firearm.

  • Publication number: 20150020423
    Abstract: A bolt action firearm that cocks the firing pin upon closing the bolt and includes a cam pin with dual heads for a high velocity rimfire cartridge. In one embodiment, actuating the main spring while closing the bolt, instead of while opening the bolt, more uniformly distributes the physical energy required by the user over the bolt actuation cycle. The dual heads of the cam pin provide symmetric reactive forces with dual cam slots, thereby preventing the cam pin from skewing or canting within the cam slots. A safety system is provided for the trigger mechanism and a robust connecting systems for the stock.

  • Publication number: 20150020425
    Abstract: The present invention teaches about a separable magazine follower situated into a magazine body. The magazine follower includes a magazine follower body and exchangeable magazine follower plate. The upper surface of the plate tooth can engage a slide stop lever tooth after the last round is fired from the magazine, and moves a slide stop lever in position that holds a slide in the rear position. The magazine follower plate can be exchanged by the new one after being depleted. The magazine follower plate is not permanently secured to the magazine follower body, but it is nested into the magazine follower body and secured via a magazine spring. The magazine follower plate is formed from material of lower hardness than the material used for slide stop lever tooth in order to prevent its excessive wearing.

  • Patent number: 8925231
    Abstract: An ammunition magazine base pad retaining plate is provided with a protrusion including a shaft portion, a flange portion having a lager cross sectional diameter than the shaft portion, and a longitudinal slot to allow lateral compression. When attached to a magazine base pad in a magazine assembly, the configuration of the base pad retaining plate eliminates the possibility that the base pad retaining plate will disengage from the base pad resulting in catastrophic disassembly of the ammunition magazine.
