Firearm Stock Assembly with Recoil Suppression Spring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stock assemblies for shoulder-fired firearms, such as shotguns and rifles, often break or detach at the connector tube to pistol grip interface and fail to reduce recoil, leading to discomfort and reduced accuracy during firing.
Innovation Solution
A stock assembly with a connector tube and attachment member that includes a compression spring to absorb recoil, enhancing the connection strength and reducing the impact of recoil on the user, while allowing for adjustable length and secure attachment to the firearm receiver or pistol grip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional stock assembly is used, then the structure is simple and easy to manufacture, but the connection breaks or detaches at the connector tube to pistol grip interface and recoil is not reduced
Solution Approach 1:
The stock assembly is divided into separate functional components: a pistol grip, a connector tube, and a recoil suppression mechanism with movable attachment members. This segmentation allows each component to be optimized independently while improving overall reliability through modular construction that prevents catastrophic failure at connection points.
Solution Approach 2:
A recoil suppression mechanism is built into the connector tube assembly that compresses upon rearward movement during firing. This beforehand cushioning absorbs recoil energy through spring compression, preventing the full impact from transferring to the pistol grip connection points and reducing stress on the assembly.
2Object-affected harmful factors
If a recoil suppression mechanism is added, then recoil impact is reduced, but the device complexity increases
Solution Approach 1:
The recoil suppression mechanism is nested within the connector tube assembly. Movable attachment members slide within the connector tube, and springs are housed within the same cylindrical space. This nesting approach consolidates multiple functions into a compact integrated unit, minimizing the increase in overall device complexity while achieving recoil suppression.
Solution Approach 2:
The attachment members are designed to move dynamically within the connector tube during firing, allowing the assembly to adapt to recoil forces. The movable components enable the system to absorb and dissipate energy through controlled motion rather than rigid resistance, reducing harmful recoil impact while maintaining structural integrity.

Function Achieved in This Case
The stock assembly effectively reduces recoil impact, enhances connection durability, and improves handling by compressing the spring to absorb the force of the firearm's rearward movement, thereby enhancing user comfort and accuracy.

AI summary
A stock assembly for attachment to a firearm assembly is described. The stock assembly includes a buttstock having a longitudinal conduit and a locking member; a connector tube with, front and back ends slidable within the buttstock conduit between a fully inserted position and a fully extended position, the tube having a longitudinal conduit; an attachment member slidable within the tube conduit between a forward position and a rearward position, the attachment member having a front end attachable to the firearm assembly and a rear end; a spring within the connector tube engaging the rear end of the attachment member, the spring urging the attachment member toward its forward position; and locking means preventing rotation of the attachment member relative to the connector tube, while allowing the attachment member to move within the tube between its forward and rearward positions.
