| 20100071242 | MAGAZINE PLUG - A magazine plug is configured to be positioned in a magazine of a shotgun to reduce the shotshell capacity of the shotgun. In one embodiment, the magazine plug has an elongated cross-sectional shape. The magazine plug is configured to rotate between a first orientation where the magazine plug can move longitudinally into and out of the magazine and a second orientation where the magazine plug is prevented from moving longitudinally out of the magazine. | 03-25-2010 |
| 20110214326 | MAGAZINE SAFETY DEVICE - Devices and methods for converting a magazine capable of holding live rounds to being capable of only holding blanks at the bottom of the magazine. A magazine safety device includes a spacer and a follower in one embodiment. The spacer can be sized and shaped so as to be placed generally between the front and rear walls of a magazine, with a portion of the spacer being disposed adjacent to a round loading opening of the magazine. Embodiments of the magazine safety device can allow a user to quickly and efficiently inspect the magazine to confirm the magazine is not loaded with live rounds. In one embodiment, the magazine safety device includes a highly visible spacer that can allow a user to confirm the magazine is loaded with blanks. Additionally, embodiments of the magazine safety device can prevent the magazine from being loaded with a plurality of live rounds. | 09-08-2011 |
| 20120227300 | MAGAZINE ADAPTOR SYSTEM - A modified elongate ammunition magazine, the magazine being modified by modifying an elongate, single plane magazine by removing its end cap so as to provide an elongate modified magazine having an upper end for attaching to said magazine well of a firearm, a lower end, and a through passageway therebetween, and a clip leg base attached thereto and also attachable to a high capacity ammunition magazine housing, the clip leg base configured such that when it is attached to said modified magazine to construct a feed clip assembly, and when the clip leg base is also attached to a high capacity magazine, and when the upper end of the modified magazine is installed into a firearm, an ammunition passageway is defined from an ammunition outlet of a high capacity ammunition magazine housing, through the modified magazine, and to a firearm. Also provided is a last linked assembly including a loose or spreadable link. | 09-13-2012 |
| 20120246988 | Systems and Methods for Limiting Capacity of Firearm Magazines - The present invention relates to systems and methods for reliably limiting the cartridge loading capacity of firearm magazines. In one embodiment, a magazine capacity limiting assembly includes a limiter body and a limiter base. The magazine capacity limiter body reliably operates with a cartridge follower of a firearm magazine. The limiter body is installed substantially within coils of the magazine's spring, thereby limiting the travel of the follower within the magazine body to limit the magazine's cartridge capacity. The limiter base is coupled to both the limiter body and the magazine's floor plate. | 10-04-2012 |
| 20130086834 | FIREARMS MAGAZINE FOR RIFLE LENGTH CARTRIDGES - A firearms magazine has compound tapered side walls and feed lips having substantially parallel end portions for maintaining contact with the cartridge as it is loaded. Removable inserts reduce the interior length and width to hold cartridges of different sizes. The insert has a channel along its height to protect the cartridge noses, and is held by a reinforcing member. A movable cartridge follower feeds the cartridges out of the magazine and has projections slideable in channels of the insert. | 04-11-2013 |

| 20150068088 | DEVICES FOR LOCKING AND REDUCING THE CAPACITY OF MAGAZINE-LOADED FIREARMS - Apparatuses for converting magazine-loaded weapons into low capacity weapons and apparatuses for locking magazine-loaded weapons are disclosed. The apparatuses may be loaded into the magazine well of a magazine-loaded weapon and may be reversible secured in place. Removal of the apparatuses requires a tool to disengage the apparatuses from the magazine well. The apparatuses may each include a body configured to be inserted into the magazine well of the firearm having a cross-sectional shape that corresponds to the interior cross-sectional shape of the magazine well, a securing mechanism in the body for securing the body within the magazine well, and a tool disjoined from the apparatus and the firearm and operable to engage the securing mechanism. The conversion apparatuses may include a seat in a fixed position on an upper portion of the body for receiving and positioning at least one cartridge of the firearm. | 03-12-2015 |
| 20150101228 | LIVE-ROUND PREVENTION WITH MAGAZINE MODIFICATION - The present invention is a modified magazine adapted to prevent live ammunition from being loaded therein and subsequently chambered into and discharged from a firearm. The magazine includes a restriction plate positioned within a cavity of the magazine and securely coupled to an interior surface of a front wall of the magazine. The restriction plate has a thickness sufficient to reduce the size of the opening of the magazine and prevent the loading of a live round into the magazine. The length of the modified opening, as reduced by the thickness of the restriction plate, is less than the length of the live round of ammunition, thereby preventing loading and/or feeding of a live round of ammunition into the magazine and further preventing discharge of a live round from the firearm. The reduced size of the opening is sufficient to receive only blank rounds of ammunition. | 04-16-2015 |
| 20150316340 | UNIVERSAL SYSTEMS AND METHODS FOR ADJUSTABLY LIMITING CAPACITY OF FIREARM MAGAZINES - The present invention relates to systems and methods for reliably limiting the cartridge loading capacity of firearm magazines. In one embodiment, a magazine capacity limiting assembly includes a limiter body and a limiter base. The magazine capacity limiter body reliably operates with a cartridge follower of a firearm magazine. The limiter body is installed substantially within coils of the magazine's spring, thereby limiting the travel of the follower within the magazine body to limit the magazine's cartridge capacity. The limiter base is coupled to both the limiter body and the magazine's floor plate. | 11-05-2015 |
| 20160061546 | FIREARM MAGAZINE CAPACITY LIMITER - The firearm magazine capacity limiter selectively limits the capacity of the magazine to comply with applicable laws or regulations. The capacity limiter has a rod including a follower contact end and an opposite attachment end that secures removably in a passage provided through a closure plate at one end of the magazine. The rod may have any length desired to limit the maximum capacity of the magazine as desired. Various attachment configurations are provided, including threaded attachment, quarter turn attachment, and sliding attachment via a capture flange on the attachment end of the rod. The capacity limiter may be used with detachable box-type magazines where the closure plate is the floor plate of the magazine, or with tubular magazines where the closure plate is the forward plug at the end of the magazine. | 03-03-2016 |
