Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current firearm action systems, particularly in AR-15 and AR-10 style firearms, fail to adequately reduce recoil and muzzle rise, impacting shooter accuracy and comfort, especially during rapid-fire sequences, and do not meet regulatory compliance requirements.
Innovation Solution
An action system that integrates a housing, buffer tube, buffer, lever arm, and action spring to manage recoil by converting linear forces into rotational energy, featuring customizable components like modular buffers and adjustable grooves for fine-tuning performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional linear compression spring and buffer are used, then the structure is simple, but recoil and muzzle rise are not adequately reduced
Solution Approach 1:
The patent transitions from traditional linear one-dimensional spring compression to a radial two-dimensional motion system. The lever arm rotates radially within the housing cavity, converting linear recoil force into rotational motion that compresses the spring in multiple dimensions, thereby more effectively mitigating recoil and muzzle rise.
Solution Approach 2:
The lever arm is designed to move radially in a curved path within the housing cavity rather than linearly. This curved radial motion allows for more efficient energy transfer and spring compression, improving recoil reduction while maintaining a compact form factor.
2Productivity
If traditional action system is used, then manufacturing is easier, but performance in rapid-fire sequences is insufficient
Solution Approach 1:
The action system employs a dynamic lever arm that rotates radially in response to recoil forces, allowing the system to adapt its mechanical advantage during the firing cycle. This dynamic response enables better management of recoil during rapid-fire sequences, maintaining accuracy and control.
Solution Approach 2:
The lever arm and spring system are pre-positioned within the housing cavity to engage immediately upon recoil application. The radial motion mechanism is already configured to convert linear force into rotational compression, providing immediate recoil mitigation without delay during rapid-fire operations.
3Object-affected harmful factors
If butt stock is made essential component, then recoil reduction is improved, but regulatory compliance becomes problematic
Solution Approach 1:
The action system integrates multiple functions within a single compact assembly: the lever arm serves as both a structural component and a recoil mitigation mechanism, the radial motion system provides both movement control and spring compression, and the housing cavity accommodates all components while maintaining a compact form. This multi-functionality achieves effective recoil reduction without requiring a traditional butt stock, maintaining regulatory compliance.
Solution Approach 2:
The patent merges the functions of the butt stock, buffer, and action system into a single integrated housing cavity assembly. The lever arm, spring, and buffer tube are combined within one compact structure, achieving the recoil reduction benefits of a butt stock while maintaining a form factor that complies with regulations prohibiting extended stock configurations.

Function Achieved in This Case
Effectively reduces recoil and muzzle rise, enhances shooter accuracy and comfort, and ensures compliance with legal standards by managing recoil forces through a customizable and adaptable mechanism.
Implementation Method 1
the lever arm moves radially when acted upon by a linear force of the buffer
Implementation Method 2
the action spring is configured to compress as the lever arm moves in the direction of the linear force applied thereto by the buffer when the firearm is fired
Data Source
AI summary
An action system for reducing recoil and muzzle rise in firearms is provided. The action system includes an outer housing having an internal cavity, a buffer tube in operable communication with a bolt carrier group of a firearm, and a slidable buffer within the buffer tube. A lever arm, pivotally secured within the outer housing, is operably connected to the buffer and moves radially under the buffer's force. A spring in the cavity engages with the lever arm, compressing as the lever arm is acted upon by the linear force produced by a bolt carrier group until the spring force exceeds the linear force, thus forcing the buffer in a direction opposite the direction of the linear force.
