Extended Gas Key for Rifle Gas Leakage Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearms often experience combustion gases during triggering events, which can cause combustion gases to be forced into the upper receiver and also into the shooter's face, causing potential for combustion gases to be forced into the upper receiver and also into the shooter's face.
Innovation Solution
The incorporation of a novel gas tube key with an extension that reduces the time duration and distance of the gap between the gas tube key and the gas tube, thereby minimizing the release of combustion gases and debris into the upper receiver and shooter's face.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the gas tube key is separated from the gas tube after 0.75 inches of bolt carrier travel, then the bolt carrier can complete its backward movement, but combustion gases are forced into the upper receiver and shooter's face
Solution Approach 1:
The gas tube key extension is designed to maintain connection with the gas tube during the initial phase of bolt carrier travel. The extension protrudes into the gas tube to ensure that combustion gases are directed into the bolt carrier before the key separates, preventing gas leakage into the upper receiver and shooter's face
Solution Approach 2:
The gas tube key extension acts as an intermediary component between the gas tube and the bolt carrier. It extends into the gas tube to create a sealed pathway that directs combustion gases properly during the separation phase, mediating the transition from connected to separated state without allowing gas escape
2Reliability
If the gas tube key maintains connection with the gas tube throughout the entire cycle, then combustion gases are contained, but the key interferes with bolt carrier movement
Solution Approach 1:
The gas tube key is designed with a dynamic separation capability where the key body remains connected to the bolt carrier while the extension portion can separate from the gas tube at the appropriate moment. This dynamic design allows the system to transition from a connected state (for gas containment) to a separated state (for unrestricted bolt carrier movement)
Solution Approach 2:
The gas tube key is segmented into two functional portions: the key body that remains attached to the bolt carrier and the extension that protrudes into and can separate from the gas tube. This segmentation allows different parts of the key to perform different functions at different times during the cycling process
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 novel gas tube key effectively reduces the duration and distance of the gap, minimizing the release of combustion gases and debris, enhancing safety and reliability by maintaining a secure connection during the firearm's cycling process.
Implementation Method 1
Cycling of a semi-automatic or automatic firearm can use the combustion gases produced during a triggering event of the firearm

AI summary
A novel gas tube key reduces the time duration that a gap exists between the gas tube key and the gas tube of a rifle, thereby reducing the time duration and the amount of combustion gas that is released into the upper receiver and into the shooter's face during cycling of the rifle's action. The novel gas tube key comprises a key body and a key extension component.
