Universal systems and methods for adjustably limiting capacity of firearm magazines

Abstract

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 body includes at least one removable and stackable component configured to enable a corresponding plurality of cartridge capacities for the firearms magazine. The limiter may also include a cupped top configured to be securely coupled the cartridge follower of a corresponding type of firearm.

What is claimed is: 
     
         1 . A universal adjustable magazine capacity limiting assembly kit configured to limit a cartridge capacity of a firearm magazine having a magazine body, a magazine spring, a cartridge follower and a magazine floor plate, the universal magazine capacity limiting assembly comprising:
 a configurable magazine capacity limiter body having a top edge configured to securely operate with a cartridge follower of a firearm magazine, the cartridge follower configured to be operatively coupled to a top of a magazine spring of the firearm magazine, wherein the limiter body is configured to be installed substantially within coils of the magazine spring, and wherein the limiter body is further configured to limit the travel of the magazine follower within the magazine body thereby limiting a cartridge capacity of the firearm magazine; and   wherein the limiter body includes at least one removable and stackable component configured to be thereby enabling a corresponding plurality of cartridge capacities for the firearms magazine.   
     
     
         2 . The universal magazine capacity limiting assembly of  claim 1  wherein the top edge of the limiter body includes a cupped section configured to be securely coupled the cartridge follower, and wherein the cartridge follower is configured for a type of magazine corresponding to a type of firearm. 
     
     
         3 . The universal magazine capacity limiting assembly of  claim 1  wherein the at least one stackable component includes a mating interface with a latch and a mating notch. 
     
     
         4 . A firearms magazine having a universal capacity limiting assembly configured to limit a cartridge capacity of the firearm magazine, the firearms magazine comprising:
 a magazine body;   a cartridge follower;   a magazine spring;   a magazine floor plate;   a configurable magazine capacity limiter body having a top edge configured to securely operate with a cartridge follower of a firearm magazine, the cartridge follower configured to be operatively coupled to a top of a magazine spring of the firearm magazine, wherein the limiter body is configured to be installed substantially within coils of the magazine spring, and wherein the limiter body is further configured to limit the travel of the magazine follower within the magazine body thereby limiting a cartridge capacity of the firearm magazine, and   wherein the limiter body includes at least one removable and stackable component configured to be thereby enabling a corresponding plurality of cartridge capacities for the firearms magazine.   
     
     
         5 . The firearms magazine of  claim 4  wherein the top edge of the limiter body includes a cupped section configured to be securely coupled the cartridge follower, and wherein the cartridge follower is configured for a type of magazine corresponding to a type of firearm. 
     
     
         6 . The firearms magazine of  claim 4  wherein the at least one stackable component includes a mating interface with a latch and a mating notch.
