Firearm Magazine Follower Grooves and Wings for Debris Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Detachable firearm magazines suffer from debris accumulation, which inhibits the movement of the follower and can lead to jamming due to their reusable nature, causing inefficiencies in reloading.
Innovation Solution
A follower design with elongate body grooves and wings that scrape and clean the magazine walls, featuring a dovetail or angled configuration to remove debris, and a beveled wing structure to enhance stability and prevent jamming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple follower and spring mechanism is used in detachable magazines, then the device complexity is reduced and ease of manufacture is improved, but debris accumulates on the magazine walls and coats the inner surfaces, causing the follower to jam or malfunction
Solution Approach 1:
The follower is divided into functional segments: the body portion that engages with the magazine wall, the grooves that channel debris, and the spring mechanism that provides upward force. This segmentation allows each part to perform its specific function while working together to solve the debris accumulation problem.
Solution Approach 2:
The grooves act as intermediaries between the follower and the debris on the magazine walls. These grooves channel and remove debris, preventing it from coating the inner surfaces and causing the follower to jam. The grooves mediate the interaction between the simple follower mechanism and the harmful debris.
2Reliability
If the follower is made with grooves and wings to scrape magazine walls, then debris removal capability is improved and follower stability is enhanced, but the device complexity increases
Solution Approach 1:
The grooves and wings are merged into a single integrated follower body structure. This merging allows the follower to simultaneously engage with the magazine wall, scrape debris, and maintain stability without requiring separate components for each function, thus limiting the increase in overall device complexity.
Solution Approach 2:
The follower body serves multiple functions: it engages with the magazine wall to provide stability, the grooves channel and remove debris, and the wings scrape the magazine walls. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity while achieving enhanced reliability.

AI summary
A follower for use in a firearm magazine includes an elongate body defining a first plane extending between a first end portion and a second, opposite end portion. The first and second end portions define grooves therein that are disposed on respective planes oriented parallel to the elongate body.
