Ambidextrous Bolt Stop Actuation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing bolt stop mechanisms in firearms, such as the M16/AR15 platform, are not ambidextrous, making them inconvenient for left-handed operators and those who may need to switch shooting styles based on combat conditions, as the bolt stop release button is typically positioned on the left side.
Innovation Solution
Incorporating a right side bolt stop release button that works in conjunction with the left side release button to provide ambidextrous functionality, allowing the bolt stop to be actuated from either side, enhancing usability for all operators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bolt stop release button is positioned on the left side for right-handed operators, then ease of operation is improved for right-handed users, but ease of operation deteriorates for left-handed operators and those who need to switch shooting styles
Solution Approach 1:
The bolt stop mechanism is designed with dual release buttons positioned on both the left and right sides of the receiver. This allows the same bolt stop mechanism to be operated from either side, making it universal for both right-handed and left-handed operators, as well as for operators who may need to switch shooting styles based on combat conditions
2Device complexity
If a single left side bolt stop release button is used, then device complexity is reduced, but adaptability deteriorates due to lack of ambidextrous functionality
Solution Approach 1:
The bolt stop release mechanism is segmented into two separate release buttons positioned on opposite sides of the receiver. Each button is independently positioned but both are functionally connected to the same bolt stop mechanism, allowing the system to maintain simplicity while providing ambidextrous operation capability

AI summary
Disclosed is a lower receiver that defines an aperture extending between a bolt stop well and an actuator well, the lower receiver including a bolts stop and a first actuator lever on one side of the lower receiver and a bolt stop actuator that includes a tooth that extends through the aperture, a second bolt release lever on the other side of the lower receiver and a rod connecting the tooth and the second bolt release lever, wherein the tooth engages the bolt stop so that actuation of the second bolt release lever moves the bolt stop and where the first and second release levers move in unison.
