Revolving Sling Mount with Rotation Stop for Firearm Charging Handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sling attachments for rifles often hinder easy switching between right-hand and left-hand operation and can become entangled or obstruct the rearward motion of the charging handle assembly during use.
Innovation Solution
A revolving sling mount system with a fixed plate and a rotatable sling-attachment plate, featuring a rotation stop to constrain the rotation to less than a full revolution, allowing seamless switching between right- and left-handed operations without entanglement and ensuring unobstructed charging handle movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional fixed sling attachment is used, then the sling is securely attached to the rifle, but the sling becomes entangled or obstructs the charging handle assembly during operation
Solution Approach 1:
The sling attachment plate is made rotatable relative to the fixed attachment plate, allowing it to dynamically adjust its position. This rotational freedom enables the sling to move away from the charging handle assembly during operation, preventing entanglement and obstruction while maintaining secure attachment.
2Device complexity
If a conventional fixed sling attachment is used, then the structure is simple, but switching between right-hand and left-hand operation is hindered
Solution Approach 1:
The rotatable attachment plate provides dynamic repositioning capability that enables easy switching between right-hand and left-hand operations. The user can simply rotate the plate to the appropriate position without complex disassembly or reconfiguration, maintaining structural simplicity while dramatically improving operational flexibility.
3Adaptability or versatility
If the revolving plate can rotate freely more than 360 degrees, then the sling has maximum flexibility, but it may obstruct the charging handle assembly
Solution Approach 1:
Rotation stops are positioned to prevent the revolving plate from rotating beyond a certain angle that would cause obstruction. This preliminary constraint stops the harmful action (obstruction) before it can occur, while still allowing sufficient rotation range for flexible sling positioning and hand switching.

AI summary
In some embodiments, a revolving sling mount for a rifle (e.g. AR-15/M4/M16) includes a stack comprising a fixed plate configured to be secured to the rifle in a fixed position, a revolving sling-attachment plate rotatably attached to the fixed plate, and fixed ring securing the revolving sling-attachment plate between the fixed plate and stop ring. Each of the fixed plate, sling-attachment plate and stop ring defines an inner aperture sized to slide over a buttstock tube of the rifle. The revolving plate rotates relative to the fixed plate about an axis perpendicular to a major plane of the fixed plate. The revolving plate includes a sling-attachment loop for attaching a sling. One or more rotation stops constrain a rotation of the sling-attachment plate so that the sling-attachment loop does not obstruct the rearward motion of a charging handle assembly of the rifle.
