At least one gate member (58, 60) is pivotally mounted at an open end of a monoblock (20) and has a first blocking member (58.1, 60.1) to inhibit feeding of an end cartridge from a feed port until the firearm (1) is cocked. The gate member (58, 60) further includes a second blocking member (58.4, 60.4) to prevent multiple cartridges (28) from feeding from the same feed port (20.3, 20.4) during a given cocking cycle. The gate member (58, 60) is operable to displace the first blocking member (58.1, 60.1) out of a cartridge feed path while placing a second blocking member (58.4, 60.4) in the feed path to of the next cartridge (28) to be fed. An interrupter (62) prevents cartridges (28) supplied by a plurality of feed ports (20.3, 20.4) from being fed simultaneously.

Abstract: Various embodiments describe techniques for tracking a firearm and generating an alert when the firearm is outside a designated authorized location. In various embodiments, a location device, such as a Global Positioning System (GPS) receiver coupled to a transmitter, is affixed to and/or associated with a firearm. A location of the firearm is transmitted via the location device to a location service module. The location service module compares the location of the firearm to at least one designated authorized location and, responsive to determining that the location of the firearm is not within the designated authorized location, generates an alert. A firearm that includes a location device is also described.

Abstract: A magazine for a firearm is adjustable for cartridge capacity using a thumb slide to select the quantity of cartridges to be held by the magazine. The thumb slide is operable in a vertical slot and below the carriage pushing up on the bullets. The thumb slide protrudes into the internal chamber through the vertical slot so as to form an obstruction preventing downward movement of the carriage beyond the obstruction. Alternatively, the thumb slide raises a platform on which a segmented spring rests. When the platform is raised, it reduces available storage in the magazine. If a capacity selection requires a smaller spring, then spring segments are removed. A set screw locks the thumb slide in place. An indicator bar shows through holes in the magazine indicating the number of cartridges remaining in the magazine. A bolt and nut is introduced to permanently prevent further adjustment.
