Firearm Barrel Extension Device with Nested Inner Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm barrel extension devices lack continuity between the barrel and the extension device, causing aesthetic and operational issues during shooting, such as a slit that disrupts the line of sight and can affect shot pattern concentration.
Innovation Solution
A firearm barrel extension device with a main body that includes an inner element perfectly adhering to the barrel's inner wall and an outer element extending outward, featuring a bottleneck portion to concentrate the shot pattern, and a secondary body that replicates the barrel's shape, ensuring seamless integration and alignment without gaps, using a threaded assembly for secure mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a traditional extension device is mounted to the muzzle of a firearm barrel, then the barrel length is extended to increase shot range, but a slit is created between the barrel and extension device that disrupts the line of sight and affects aesthetic appearance
Solution Approach 1:
The extension device incorporates an inner element that is housed inside the barrel, nested within the barrel structure rather than merely attached externally. This nesting arrangement allows the extension device to integrate with the barrel internally, eliminating the external slit and achieving continuity of the line of sight while still extending the effective barrel length.
Solution Approach 2:
The inner element acts as an intermediary component between the barrel and the outer element. It is perfectly adhered to the inner barrel wall, creating a seamless transition and eliminating the slit that would otherwise exist between the barrel and the extension device, thus maintaining the continuity of the line of sight.
2Length of moving object
If an extension device with a slit between the barrel and extension device is used, then the barrel length is extended, but the aesthetic impact and shot pattern concentration are compromised
Solution Approach 1:
The inner element nested inside the barrel creates a seamless internal passage for the shot pattern, eliminating disruptions caused by external slits. This nesting configuration ensures that the shot pattern remains concentrated and undisturbed while the barrel length is extended through the outer element.
Solution Approach 2:
The inner element serves as an intermediary that perfectly adheres to the inner barrel wall, creating a continuous and smooth bore surface. This eliminates turbulence and disruption to the shot pattern, maintaining manufacturing precision and shot concentration while allowing barrel length extension.
3Length of moving object
If a fixed extension device is installed on the firearm, then the line of sight is extended, but the device cannot be quickly adjusted or replaced for different shooting needs
Solution Approach 1:
The extension device is segmented into separable components including the inner element, outer element, and attachment body that can be independently assembled and disassembled. This segmentation allows the device to be quickly adjusted or replaced for different shooting needs while maintaining the extended line of sight when assembled.
Solution Approach 2:
The extension device transitions from a fixed, permanent installation to a dynamic, adjustable configuration through the threaded attachment mechanism. The attachment body can be screwed onto or removed from the main body, allowing the device to adapt between different shooting scenarios while maintaining structural integrity during use.

AI summary
The invention is an extension device (1) of a firearm (500) mountable in an operating configuration, to a muzzle (555) of a barrel (550) of the firearm (500). The extension device (1) comprises a main body (10) which comprises an inner element (11) housable inside the barrel (550) and suitable to firmly engage with an inner barrel wall (550') and an outer element (12) which extends axially adjacent to the inner element (11) and is suitable to be arranged outside the barrel (550) with the inner element (11) housed in the barrel (550). The extension device further comprises a secondary body (20) fitted axially on the main body (10) and an attachment body (30) fitted axially on the outer element (12) and fixable thereto performing an axial thrust action on the secondary body (20) until it closes in a pack on the muzzle (555) of the firearm (500).
