Abstract
A number of embodiments of a firearm are disclosed where the firearm includes a magazine configured to hold the bolt in an open position when the magazine is empty. In one embodiment, the firearm includes a bolt stop mechanism that moves between a first position where it allows the bolt to cycle between an open position and a closed position and a second position where it holds the bolt in the open position. The magazine is configured to actuate the bolt stop mechanism to the first position when the magazine is empty.
Claims16
A rotary magazine comprising:
- a housing having an interior cavity and a feed opening;
- a rotor rotatably positioned in the interior cavity of the housing, the rotor being configured to feed cartridges through the feed opening;
- a tab movable between a retracted position and an extended position relative to the housing by rotation of the rotor;
- wherein the tab is configured to operatively engage a pivot member of a bolt stop mechanism to maintain a bolt of a firearm in an open position by moving the tab into the extended position.
A rotary magazine for a firearm, the firearm including a pivot member operatively coupled to a bolt stop mechanism, the bolt stop mechanism being configured to hold a bolt of the firearm in an open position, the rotary magazine comprising:
- a housing having an interior cavity and a feed opening;
- a rotor rotatably positioned in the interior cavity of the housing, the rotor being configured to feed cartridges through the feed opening;
- a tab movable between a retracted position and an extended position relative to the housing by rotation of the rotor, the tab being configured to contact and rotate the pivot member of the firearm as the tab moves to the extended position;
- wherein rotation of the pivot member actuates the bolt stop mechanism to hold the bolt of the firearm in an open position.
A rotary magazine comprising:
- a housing having an interior cavity and a feed opening;
- a rotor having a protrusion, the rotor rotatably positioned in the interior cavity of the housing, the rotor being configured to feed cartridges through the feed opening;
- a tab having a notch, wherein rotation of the rotor causes the protrusion to push on the notch of the tab to move the tab from a retracted position to an extended position relative to the housing;
- wherein the tab is configured to completely reside within the housing in the retracted position.
