Firearm Sling Fitting with Transitional Crossbar for Rapid Stance Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sling systems, including traditional 2-point and point-type slings, hinder rapid side-to-side transitions and are not optimized for dynamic combat environments, particularly in close-range urban combat scenarios, where soldiers need to change stances quickly while maintaining weapon security and comfort.
Innovation Solution
A sling fitting with a transitional crossbar that allows a point-type sling to move from left to right across a firearm, enabling use in either handed stance without detachment and providing a convertible system for different carry modes with rapid length adjustment, ensuring secure attachment and increased range of motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a traditional 2-point sling is used to secure the weapon, then the weapon can be carried comfortably over long distances, but the weapon becomes stowed in a non-useable orientation and requires manual adjustment for rapid transitions
Solution Approach 1:
The sling system incorporates a quick-release mechanism and movable attachment points that allow the sling configuration to dynamically change from a secure 2-point carry position to a rapid side-to-side transition position, enabling both long-distance comfort and quick operational responses
Solution Approach 2:
The sling is divided into multiple adjustable segments with independent attachment points, allowing each segment to be positioned independently to achieve either a stable 2-point configuration for carrying or a simplified configuration for rapid transitions between shooting stances
2Ease of operation
If a point-type sling is used to allow greater freedom of motion, then the sling has less loose material to become entangled, but the weapon becomes unstable and requires constant hands-on control
Solution Approach 1:
The sling system dynamically adjusts its stability characteristics based on the operational phase: during movement, it provides freedom of motion with reduced entanglement, and during weapon engagement, it automatically stabilizes the weapon through its attachment geometry and tension distribution
Solution Approach 2:
The sling changes its functional parameters by adjusting the attachment point positions and sling tension, transitioning from a loose configuration that allows freedom of motion to a tensioned configuration that stabilizes the weapon during hands-off movement
3Ease of operation
If side-mounted 2-point or 3-point slings are used to improve usage position, then the weapon can be carried on the front of the body in a usable low-ready position, but manual adjustment is required for transitions and strap material interferes with chest-mounted equipment
Solution Approach 1:
The sling incorporates dynamic adjustment mechanisms that automatically reposition attachment points and adjust strap tension when transitioning between different carry positions, eliminating the need for manual adjustment while maintaining the usable low-ready position
Solution Approach 2:
The design extracts and removes excess strap material that would interfere with chest-mounted equipment while maintaining the essential 2-point or 3-point attachment functionality, reducing overall sling bulk and interference potential

AI summary
The present invention is a sling system utilizing a rear sling fitting for a long firearm, such as a rifle. Such fittings typically are positioned between the stock and receiver. It presents a fitting body with an aperture to slide over a rifle receiver tube and a connection bar extending from a reverse of the fitting body. A point-type sling attachment may then be attached to the connection bar and be able to slide left and right across the back of the weapon, allowing for quickly adaptable left or right positioning of the weapon. Registration geometry may be added and positioned to further allow interface with weapon geometry and prevent rotation of the fitting during use. The connection bar may be positioned on another component of the weapon, such as the receiver or the stock, should the weapon not have a receiver extension tube. A convertible sling and forward sling mount are also disclosed for cooperative use with the fitting, completing the system.
