Side-Loading Magazine With Sliding Panel And Follower
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firearm laws in states like California and New York require semi-automatic firearms to have fixed, non-removable magazines, posing a challenge for users who need to load ammunition without violating these regulations.
Innovation Solution
A fixed magazine design for firearms, featuring a sliding side panel or rear panel that can be opened for easy loading without disassembly, using a finger-pull mechanism and spring-loaded system to allow access to the magazine body while preventing removal from the firearm, thus complying with legal requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed magazine is used to comply with firearm laws, then legal compliance is achieved, but ammunition loading becomes difficult and complex
Solution Approach 1:
The magazine is divided into separate components: a fixed magazine body that remains attached to the firearm, and a removable follower assembly that can be extracted through the magazine opening. This segmentation allows the magazine to remain fixed for legal compliance while enabling easy follower removal for ammunition loading.
Solution Approach 2:
The follower assembly is designed to be extractable from the magazine body through the magazine opening without removing the entire magazine from the firearm. This extraction mechanism allows users to remove and replace the follower for ammunition reloading while maintaining the fixed magazine configuration required by law.
2Reliability
If a fixed magazine design is implemented, then magazine removal is prevented, but ammunition reloading requires disassembly or tools
Solution Approach 1:
The magazine system is segmented into a permanent magazine body and a removable follower assembly. The follower contains the ammunition and can be independently extracted, separating the reloading function from the magazine attachment/detachment function. This allows simple follower removal through the magazine opening without requiring magazine disassembly or special tools.
Solution Approach 2:
The magazine opening serves dual purposes: it allows the magazine to be inserted into the firearm and also serves as the extraction path for removing the follower during reloading. This self-service design eliminates the need for separate disassembly procedures or specialized tools for reloading.
3Reliability
If the magazine is made permanently attached to the firearm, then compliance with fixed magazine laws is achieved, but user convenience for loading is reduced
Solution Approach 1:
The magazine assembly is segmented into a fixed magazine body that remains permanently attached to the firearm, and a removable follower assembly that can be easily extracted through the magazine opening. This segmentation maintains legal compliance while restoring loading convenience through simple follower removal and replacement.
Solution Approach 2:
The magazine opening is designed to serve multiple functions: it allows magazine insertion into the firearm, provides access for follower extraction during reloading, and maintains the fixed magazine configuration for legal compliance. This multi-functionality enhances user convenience without compromising legal requirements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to load ammunition conveniently and legally into fixed magazines without tools, ensuring compliance with state laws while maintaining the firearm's functionality.
Implementation Method 1
a cartridge follower spring configured to be compressed by the cartridge follower when the at least one finger pull is engaged with the bottom hook, and configured to expand when the at least one finger pull is disengaged from the bottom hook, thereby allowing the cartridge follower to urge the stack of cartridges towards the feeding end of the ammunition magazine

AI summary
An affixable magazine in compliance with new firearms laws that enables citizens to legally own and effectively operate a firearm, such as an AR-15. The affixable magazine allows a user to easily load ammunition through a sliding panel without removing the magazine from the firearm, disassembling the action, or using tools. The affixable magazine includes: a magazine body configured to contain a stack of cartridges, and an attachable blocking tab for blocking removal of the ammunition magazine from the magazine well, the attachable blocking tab being attached after insertion of the ammunition magazine into the magazine well, and before re-engaging the upper receiver with the lower receiver. The affixable magazine also includes a magazine body having an opening, with a sliding panel configured to alternately cover or reveal the opening, the magazine body including: at least one finger-pull slot with a bottom hook for locking the follower.
