Adjustable Firearm Stock With Rotating Butt Pad
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Soldiers face challenges when shooting with bulky garments or body armor, as existing firearm stock designs fail to stabilize the weapon effectively in various shooting positions and do not allow for personal adjustment of the butt pad contour.
Innovation Solution
A modular firearm stock assembly with an adjustable butt pad and locking mechanism that engages with the receiver extension tube, allowing for axial positioning and accommodating external accessories, enabling stable operation in different shooting positions and personal preference adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional firearm stock designs are used, then the structure is simple, but the stock cannot stabilize the weapon effectively in various shooting positions when wearing bulky gear
Solution Approach 1:
The stock assembly incorporates adjustable components including a movable rear butt member that can be repositioned along the stock body, and an adjustable butt pad with contoured regions that can be rotated to different orientations. These dynamic adjustment capabilities allow the stock to adapt to various shooting positions and bulky gear configurations, resolving the contradiction between stability and structural simplicity.
Solution Approach 2:
The stock assembly is divided into separable components including the stock body, rear butt member, and butt pad, each with independent adjustment mechanisms. The rear butt member can be independently positioned, and the butt pad can be independently oriented, allowing targeted stabilization without requiring complete redesign of the entire stock structure.
2Adaptability or versatility
If fixed butt pad design is used, then the manufacturing is simple, but the user cannot adjust the contour angle according to personal preference
Solution Approach 1:
The butt pad is designed with rotational capability relative to the stock body, allowing users to adjust the contour angle to their personal preference. The butt pad includes contoured regions that can be rotated to different orientations, providing adaptability for different body types and gear configurations without requiring complex adjustment mechanisms.
Solution Approach 2:
The butt pad incorporates specific contoured regions with different shapes and orientations that can be selectively positioned against the user's body. This local quality variation allows tailored fit and comfort for different users while maintaining a relatively simple overall structure.
3Adaptability or versatility
If the stock assembly is made adjustable for axial positioning, then the adaptability to different positions is improved, but the locking mechanism complexity increases
Solution Approach 1:
The stock assembly includes adjustable axial positioning capabilities through movable components that can be repositioned along the stock body. The locking mechanism uses simple latching features that engage at predetermined positions, providing positioning flexibility without requiring complex adjustment systems.
Solution Approach 2:
The locking mechanism is designed with predetermined latching positions that are pre-configured at specific axial locations. This preliminary positioning allows users to quickly adjust to different positions without complex adjustment procedures, reducing the perceived complexity while maintaining flexibility.

AI summary
A stock assembly for use with a firearm includes a stock assembly body having a forward end, an opposing rear end, and a bottom portion defined between the forward end and rear end. A locking mechanism may be disposed on the stock assembly body. A rear butt member may be adjustably positionable on the rear end of the stock assembly body and include a housing defining an end surface forming a base region and a protruding region extending from the base region. The rear butt member may be adjustably positionable relative to the stock assembly body to position the rear butt member base region on a surface extending forward of a user and the protruding region proximate the user for operation of the firearm by the user.
