Rotatable Firearm Stock with Toothed Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firearm grip stocks often cause the weapon to cant when fired, leading to misalignment of sights, which diminishes performance, especially in competitive shooting, due to the user's natural hand position.
Innovation Solution
A rotatable firearm stock system with interconnected grip and butt stock portions that allow angular adjustments via toothed interfaces, enabling the grip portion to be oriented between -20 to 20 degrees relative to both the grip and butt stock in 4-degree increments to compensate for cant.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the grip stock is vertically aligned with the receiver and butt stock, then the structural connection is simple, but the user's natural hand position causes the firearm to cant when fired
Solution Approach 1:
The grip stock is made rotatable relative to the receiver and butt stock through a connection interface with multiple engagement positions. This allows the grip stock to be dynamically adjusted to different angular orientations (including vertical and angled positions) to compensate for the user's natural hand position and prevent canting, while maintaining simple structural connection through the toothed interface mechanism
2Reliability
If the grip stock is made rotatable with multiple angular orientations, then the sight alignment can be maintained, but the connection interface becomes more complex
Solution Approach 1:
The connection interface is segmented into discrete engagement positions with specific angular orientations (e.g., 0°, 15°, 30°, 45°). Each position provides a distinct angular relationship between the grip stock and receiver, allowing precise control over the grip angle while maintaining a relatively simple overall structure through standardized toothed interfaces
3Adaptability or versatility
If the grip stock allows angular adjustment, then the canting issue can be compensated, but the manufacturing precision requirements increase
Solution Approach 1:
The connection interface is designed with discrete engagement positions that provide predetermined angular orientations. This dynamic adjustment capability allows the grip stock to be positioned at specific angles (e.g., 0°, 15°, 30°, 45°) to compensate for canting, while the discrete nature of the engagement positions simplifies manufacturing precision requirements compared to continuous adjustment mechanisms

AI summary
Apparatus, systems, and methods for a rotatable firearm stock. The stock includes a first grip portion configured to be attached to a firearm receiver. The stock includes a second grip portion having a first axis of rotation. The stock includes a first connection interface between the first grip portion and the second grip portion. The first connection interface enables the second grip portion to be connected to the first grip portion in more than one angular orientation about the first axis of rotation. The second grip portion includes a second axis of rotation. The stock includes a butt stock positioned adjacent to the second grip portion. The stock includes a second connection interface between the second grip portion and the butt stock. The second connection interface enables the second grip portion to be connected to the butt stock in more than one angular orientation about the second axis of rotation.
