Firearm Adapter with Obstruction-Reaching Anchor and Alignment Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current firearm adapters fail to securely and concentrically attach muzzle devices like suppressors to firearms with obstructions or abnormal profiles, making it difficult to fit suppressors on a wide range of barrels without modifying the barrel during manufacturing.
Innovation Solution
A universal adapter with an anchor and outer sheath design that can reach around barrel obstructions, featuring a semicircular cross-section and adjustable gap to securely attach to the barrel, along with a frustoconical alignment guide to ensure axial alignment and a threaded suppressor mount for easy attachment of muzzle devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a universal adapter design is used to fit various firearm barrels, then compatibility with existing firearms is increased, but securing concentric attachment to barrels with obstructions becomes difficult
Solution Approach 1:
The adapter is divided into two main segments: an outer housing that provides the universal interface and an inner anchor that interfaces with the barrel. This segmentation allows the outer housing to maintain a consistent universal design while the inner anchor can be positioned at different locations to accommodate various barrel profiles and obstructions, thereby achieving both versatility and reliable attachment.
Solution Approach 2:
The alignment guide acts as an intermediary component between the outer housing and the inner anchor. It provides a frustoconical surface that guides the barrel into proper alignment with the suppressor bore, ensuring concentric attachment even when the barrel has obstructions. This intermediary element mediates between the universal outer housing and the variable barrel interfaces.
2Adaptability or versatility
If barrel obstructions are present, then firearm functionality is maintained, but adapter attachment becomes problematic
Solution Approach 1:
Instead of trying to make the adapter conform to the barrel obstruction, the design inverts the approach by having the barrel conform to the adapter's alignment guide. The frustoconical alignment guide surface causes the barrel to be funneled into proper alignment, reversing the traditional adaptation approach and simplifying installation despite obstructions.
Solution Approach 2:
The alignment guide performs preliminary alignment action before the final attachment is secured. The frustoconical surface pre-positions the barrel in the correct orientation and alignment as it is inserted into the adapter, ensuring proper concentric attachment before the suppressor is fully installed, thereby easing the overall installation process.
3Reliability
If a custom adapter is made for each barrel profile, then secure attachment is achieved, but manufacturing costs increase
Solution Approach 1:
The outer housing is designed as a universal component that can interface with multiple suppressor types and configurations. This multi-functional design allows a single outer housing design to serve multiple purposes across different firearm applications, reducing the need for custom adapters for each barrel profile while maintaining secure attachment through the standardized inner anchor interface.

AI summary
A flexible fit, easy to attach and align, firearm adapter that allows secure fitment of a muzzle device, such as a suppressor, to a broad range of firearm sizes and shapes, with a single device. These firearms would include difficult to fit barrel profiles that in many cases would go unsuppressed without this improvement over the prior art. An embodiment includes an anchor securable to a smooth section of a firearm barrel and a housing adapted to engage the anchor. The anchor and housing are sized to reach over or around barrel obstructions. An embodiment includes an alignment guide to bring the barrel into axial alignment with the muzzle device.
