Adjustable Gunstock Comb and Butt Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard gunstocks often fail to accommodate individual shooter physiological changes and variations, leading to inconsistent gun fit and reduced accuracy over time, as they are designed for the average user and do not allow for sufficient adjustment in comb height, butt position, and orientation.
Innovation Solution
An adjustable gunstock with a base and mount system that includes relocation and adjustment members, allowing for lateral, vertical, and angular adjustments of the comb and butt, utilizing screw posts, slider blocks, and rack-and-pinion mechanisms to customize the fit to the shooter's body, enabling precise alignment with the scope and optimal shooting position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard mass-produced gunstocks are used, then manufacturing cost and simplicity are maintained, but adaptability to individual shooters and long-term fit consistency deteriorate
Solution Approach 1:
The gunstock is divided into separate adjustable components: the comb is detachable and adjustable relative to the stock body, and the butt is adjustable along the length of pull. This segmentation allows each component to be independently adjusted to fit individual shooters while maintaining a relatively simple overall structure that can be manufactured cost-effectively.
Solution Approach 2:
The stock incorporates dynamic adjustment mechanisms that allow the comb and butt positions to be changed by the shooter. The comb adjustment mechanism enables vertical and horizontal positioning changes, while the butt mechanism allows adjustment along the length of pull, providing adaptability without requiring a completely complex custom-made stock for each user.
2Manufacturing precision
If custom-made stocks are manufactured for each shooter, then gun fit precision and shooting accuracy are improved, but manufacturing cost and time consumption increase
Solution Approach 1:
The adjustable stock design creates a universal platform that can accommodate multiple shooters with different physiological characteristics. Instead of manufacturing custom stocks for each individual, a single adjustable stock model can serve multiple users through its comb and butt adjustment mechanisms, achieving precise fit for each shooter while maintaining economical mass production of the base stock design.
3Ease of operation
If the gunstock is designed for the average user, then manufacturing simplicity is maintained, but fit consistency for individual shooters deteriorates
Solution Approach 1:
The stock is pre-configured with adjustment mechanisms and features that enable shooters to customize the fit before use. The comb and butt are designed with built-in adjustment capabilities that allow shooters to achieve consistent, reliable fit for their specific physiology without requiring complex external tools or procedures, maintaining ease of operation while ensuring fit consistency.

AI summary
There is proposed an adjustable gunstock for a firearm, comprising, a base, a mount, at least one relocation member and at least one adjustment member. The base is fixedly connectable to a stock body of the firearm and the mount adjustably engageable with the base. The mount, or a part attachable thereto, forms a shooter's body engaging portion. The at least one relocation member is couplable to the base and configured to adjust the mount relative to the base in a first direction. The at least one adjustment member configured to engage the least one relocation member, and is couplable to the mount, to thereby adjust the mount relative to the base in a second direction, wherein the mount is movable both laterally of, and away from or towards, the stock body of the firearm.
