Gas Regulation Latch with Tactile Feedback for Suppressor Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gas-operated firearms face issues with inconsistent gas pressure when using sound suppressors, leading to potential damage or malfunction due to improper gas system settings, as users often forget to adjust the gas plug, resulting in unreliable performance.
Innovation Solution
A gas regulation element with a latch system that provides audible and tactile feedback when correctly positioned for suppressor use, securing the gas plug against accidental changes and ensuring proper gas flow characteristics, preventing unwanted loosening or misalignment of the suppressor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a suppressor is installed, then sound reduction is achieved, but gas backpressure increases causing over-pressurization of the gas system
Solution Approach 1:
The patent applies parameter changes by providing multiple aperture sizes in the gas plug that can be selected based on whether a suppressor is installed. When a suppressor is installed, a smaller aperture is selected to reduce the amount of gas admitted to the gas system, compensating for the increased backpressure and preventing over-pressurization. This directly addresses the contradiction by changing the gas flow parameter to adapt to the altered pressure conditions caused by the suppressor.
2Stress or pressure
If gas plug aperture is reduced to compensate for suppressor backpressure, then gas system pressure is controlled, but firearm reliability decreases due to user error in setting
Solution Approach 1:
The patent implements feedback through a latch mechanism that provides tactile and audible confirmation when the gas plug is correctly positioned. The latch engages with corresponding features on the suppressor or gas block to indicate proper installation and correct aperture selection. This feedback mechanism ensures users can verify the gas plug setting, preventing reliability issues caused by incorrect adjustment while maintaining the pressure control benefits of the reduced aperture.
Solution Approach 2:
The patent applies preliminary action by providing a latch mechanism that secures the gas plug in the correct position before firing occurs. The latch is designed to engage automatically or be easily set by the user during assembly, ensuring the gas plug is properly positioned and secured before the firearm is used. This preliminary securing action prevents user error during operation, maintaining reliability while using the smaller aperture for suppressor compatibility.
3Adaptability or versatility
If multiple aperture options are provided in the gas plug, then adaptability to different ammunition and suppressors is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the gas plug into distinct sections with different aperture sizes. Each aperture option is clearly separated and can be independently selected by rotating or adjusting the gas plug to the appropriate position. This segmentation allows the single gas plug component to provide multiple aperture options for different ammunition types and suppressor configurations, achieving high adaptability without requiring multiple separate components, thus limiting the increase in device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures safe and reliable operation by providing clear feedback on correct gas plug settings, preventing damage and ensuring consistent performance, even when a sound suppressor is installed, thus enhancing user safety and firearm reliability.
Implementation Method 1
the energy produced in firing a round to cycle a bolt (bolt carrier and bolt) and load the next round. This includes machine guns and semi-automatic rifles of many types. One type of system for transferring energy to the bolt employs the gas pressure developed behind the bullet in the barrel upon discharge
Implementation Method 2
The latch element gives the user audible or tactile feedback upon installation of an accessory device when the gas regulation element is a correct position suited to use of the accessory
Implementation Method 3
The latch may engage a circular array of elements on the rear face of the suppressor, and may have an angled cam face to provide ratcheting engagement for installation, and to resist removal or loosening without deliberate actuation of the latch

AI summary
A gas-operated firearm has a barrel defining a bore with a gas block defining a chamber communicating with the bore via a gas passage. A gas regulation element has a first position and a second position, and serves to provide different gas flow characteristics in the different positions. The latch element gives the user audible or tactile feedback upon installation of an accessory device when the gas regulation element is a correct position suited to use of the accessory, and not when in the other position unsuited to accessory usage. The accessory may be a sound suppressor, and the latch may serve to secure the gas regulation element against position change. The latch may engage a circular array of elements on the rear face of the suppressor, and may have an angled cam face to provide ratcheting engagement for installation, and to resist removal or loosening without deliberate actuation of the latch.
