Last Round Link Feed System for Firearm Magazine Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm magazine systems are limited in their ability to convert a single high capacity magazine for use with multiple firearms of the same caliber, requiring separate magazine configurations and modifications for each firearm.
Innovation Solution
A clip leg base system that facilitates the conversion of a firearm magazine into a feed tube subcomponent, allowing a single high capacity magazine to be used with multiple firearms by creating a feed clip assembly with a defined ammunition passageway, utilizing a modified magazine with a through passageway and clip legs for attachment to a double drum housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single high capacity magazine is used for multiple firearms, then ammunition storage capacity and versatility are improved, but compatibility and feeding reliability across different firearm models deteriorate
Solution Approach 1:
The magazine system is divided into two functional segments: a universal high-capacity double drum housing that provides ammunition storage, and firearm-specific feed clip assemblies that ensure proper feeding geometry. This segmentation allows the housing to be shared across multiple firearms while maintaining feeding reliability through model-specific feed clips.
Solution Approach 2:
A feed clip assembly serves as an intermediary component between the universal double drum housing and the firearm-specific magazine well. The feed clip adapts the ammunition output from the housing into the specific feeding requirements of each firearm model, ensuring compatibility and reliability.
2Reliability
If separate magazine configurations are created for each firearm, then ammunition feeding reliability for each firearm is improved, but device complexity and the number of required magazines deteriorate
Solution Approach 1:
The double drum housing is designed as a universal component that can serve multiple firearm models simultaneously. By making the housing multi-functional and pairing it with firearm-specific feed clips, the system reduces the total number of magazine units needed while maintaining feeding reliability for each firearm type.
Solution Approach 2:
The magazine system is divided into two functional segments: a universal high-capacity double drum housing that provides ammunition storage, and firearm-specific feed clip assemblies that ensure proper feeding geometry. This segmentation allows the housing to be shared across multiple firearms while maintaining feeding reliability through model-specific feed clips.
3Productivity
If a modified magazine with through passageway is used, then ammunition flow efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The through passageway is pre-formed as an integral part of the feed clip assembly during manufacturing. This preliminary incorporation of the passageway structure simplifies the overall manufacturing process compared to creating complex internal channels in the housing, while still achieving efficient ammunition flow.

AI summary
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.
