Firearm Silencer Mount Using Primary and Backup Lugs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound suppressor attachment methods for firearms are cumbersome, inconvenient, unreliable, fragile, and expensive, and they often prevent the use of other muzzle devices like flash hiders or muzzle brakes.
Innovation Solution
A novel silencer mount system that uses primary and backup lugs to securely attach and detach a silencer from a muzzle device or firearm barrel, allowing for quick and reliable installation and removal, and enabling the use of other muzzle devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If threads are used to attach the sound suppressor to the firearm barrel, then the sound suppressor can be installed and removed, but the attachment process takes excessive time and effort, and the threads can become damaged making installation impossible
Solution Approach 1:
The attachment system is divided into separate components: a muzzle device with external lugs and a sound suppressor with internal lugs. This segmentation allows for a more reliable mechanical connection that is less prone to damage compared to traditional threaded attachments, while still maintaining the ability to install and remove the suppressor quickly without excessive time and effort.
Solution Approach 2:
Instead of using internal threads in the sound suppressor to mate with external threads on the barrel (traditional approach), the patent inverts the design by placing external lugs on the muzzle device that engage with internal lugs in the sound suppressor. This inversion creates a more robust attachment mechanism that prevents thread damage while maintaining ease of operation.
2Object-affected harmful factors
If a sound suppressor is attached to the firearm muzzle, then the audible report is reduced, but it becomes impossible to use other muzzle devices like flash hiders or muzzle brakes
Solution Approach 1:
The muzzle device is designed with a universal attachment system that can accommodate multiple types of muzzle devices. The lug-based mechanism allows the sound suppressor to be attached when needed for noise reduction, while the same interface can also accommodate flash hiders, muzzle brakes, or other muzzle devices, providing versatility and adaptability without compromising audible report reduction when the suppressor is installed.
3Ease of operation
If traditional attachment methods are used, then the sound suppressor can be installed, but it can rattle loose during use and the attachment system is fragile
Solution Approach 1:
The attachment system uses multiple discrete lugs (typically three or more) distributed around the circumference of the muzzle device and sound suppressor interface. This segmented approach distributes the mechanical loads and prevents the sound suppressor from rattling loose, creating a stable attachment that is resistant to vibration and shock while maintaining ease of installation.
Solution Approach 2:
The lugs are designed with curved surfaces that mate together, creating a spherical or rounded interface rather than sharp angular connections. This curvature allows for better load distribution and reduces stress concentration points, preventing the attachment from becoming fragile while maintaining the ability to install and remove the sound suppressor easily.

AI summary
A mount for mounting a firearm sound suppressor or silencer to a firearm muzzle or muzzle device operates by using primary mounting lugs on the suppressor which engage sockets on the muzzle device. The primary lugs prevent the suppressor from axially moving with respect to the muzzle device, thus causing them to be fixed together as a unitary device. Angled bearing faces on the muzzle device and the sound suppressor are pressed against each other by rotating the sound suppressor on threads which drive the angled bearing faces together, thus tightening the primary lugs within their sockets. Backup lugs on the silencer engage an annular groove on the muzzle device to retain the silencer on the firearm to which it is mounted in case of failure of the primary lugs. Rapid attachment and detachment are supported by these structures.
