Suppressor Mounting Assembly with Locking Nut and Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing muzzle accessory mounting systems, particularly for suppressors, face challenges in securely retaining the accessory on the firearm barrel under high temperatures and recoil forces, leading to loosening issues and difficulty in removal after prolonged use.
Innovation Solution
A mounting assembly comprising a locking nut and locking ring, which engages between the accessory mount and muzzle adapter, providing a secondary retention mechanism that remains effective even under thermal cycling and recoil, allowing for easy removal by loosening the locking nut.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional sealing tapers are used to retain the muzzle accessory, then the accessory can be securely mounted initially, but the retention fails under high temperatures and recoil forces
Solution Approach 1:
The mounting system is divided into separate functional components: a muzzle adapter with external threads, a suppressor mount with internal threads, and a distinct locking mechanism (locking nut and locking ring). This segmentation allows each component to be optimized independently, with the locking mechanism specifically designed to withstand thermal expansion and recoil forces that cause traditional integrated sealing tapers to fail.
Solution Approach 2:
A locking ring is introduced as an intermediary element between the locking nut and the muzzle adapter. This locking ring with tapered outer surface engages with both the locking nut's tapered inner surface and the muzzle adapter's bearing surface, creating a mechanical intermediary that distributes and manages the thermal and mechanical stresses, preventing the direct failure mode of traditional sealing tapers.
2Ease of operation
If traditional sealing tapers are used to retain the muzzle accessory, then the mounting structure remains simple, but removal becomes difficult after prolonged use
Solution Approach 1:
The locking mechanism transitions from a static permanent bond (traditional sealing tapers) to a dynamic reversible connection. The locking nut can be rotated to engage or disengage the locking ring, allowing the suppressor to be securely retained during service but easily removed when needed. This dynamic mechanism maintains simple operation throughout the service duration without the progressive tightening problem of traditional tapers.
3Reliability
If a secure retention mechanism is implemented to withstand recoil and heat, then retention reliability improves, but device complexity increases
Solution Approach 1:
The locking nut serves multiple functions simultaneously: it provides the primary locking action through thread engagement, creates compressive force through its tapered inner surface, and enables easy removal through reversible rotation. The locking ring similarly provides both the mechanical locking function and the alignment function through its tapered outer surface. This multi-functionality reduces the need for additional separate components, maintaining relative simplicity while achieving high reliability.
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 assembly securely retains the muzzle accessory during use and allows for easy removal without additional complexity, overcoming the limitations of traditional sealing tapers that fail under heat and torque.
Implementation Method 1
The locking ring has an inside face configured to engage the bearing surface on the muzzle adapter and has an outside face that includes an outside taper configured to engage the inside taper of the locking nut. When the locking nut is tightened onto the accessory mount, the locking ring becomes bound between the locking nut and the muzzle adapter.

AI summary
An assembly is configured for retaining a muzzle accessory mounted on a firearm barrel or to a muzzle adapter on the barrel, where the muzzle accessory has a mount with female threads on an inside and male threads on an outside of the mount. The outside of the muzzle adapter has male threads and a bearing surface. A locking nut has inner female threads and an inside taper located proximally of the female threads. A locking ring has a tapered outside face configured to engage the inside taper of the locking nut and an inside face configured to engage the bearing surface. When assembled, the mount is threaded onto the muzzle adapter and the locking nut is threaded onto the accessory mount with the locking ring engaging the bearing surface of the muzzle adapter and the inside taper of the locking nut.
