Adjustable Tuning Device for Firearm Barrel Vibration Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing barrel tuners require gunsmith modifications, combine with proprietary muzzle devices, and do not support user-selected muzzle devices, limiting their versatility and compatibility.
Innovation Solution
An adjustable tuning device with a mounting member and tuning weight that can be axially positioned to accommodate user-selected muzzle devices, allowing for adjustable weight distribution without modifying the barrel or restricting muzzle device usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a proprietary muzzle brake is combined with the barrel tuner, then the device provides integrated tuning and muzzle brake functions, but the user cannot use their own selected muzzle device
Solution Approach 1:
The device is divided into two independent components: a mounting member that attaches to the barrel and a separate user-selected muzzle device. The mounting member has a forward portion that receives the muzzle device and a rear portion that interfaces with the barrel, allowing the tuning function and muzzle device function to be separated yet work together
Solution Approach 2:
The mounting member is designed with universal compatibility features including a forward portion that can accommodate various user-selected muzzle devices and a rear portion that interfaces with standard barrel threads. This allows a single mounting member to serve multiple functions with different muzzle devices
2Ease of manufacture
If gunsmith modifications are required to add contouring and threads to the barrel, then the barrel tuner can be accommodated, but the modification process becomes complex and time-consuming
Solution Approach 1:
The mounting member is pre-manufactured with the necessary threads and structural features already in place. The barrel does not require any modifications because the mounting member is designed to interface with existing barrel threads, eliminating the need for preliminary gunsmith work
Solution Approach 2:
The mounting member acts as an intermediary component between the barrel and the muzzle device. It provides the necessary threading and structural interface without requiring modification to the barrel itself, simplifying the installation process
3Strength
If the mounting member has a larger external diameter, then it provides better structural support, but it cannot accommodate barrels with larger exterior profiles
Solution Approach 1:
The mounting member has different diameters at different locations: a larger external diameter at the externally threaded portion for structural support and a smaller internal diameter at the forward portion for receiving the muzzle device. This local variation in dimensions allows both strength and compatibility

AI summary
An adjustable tuning device includes an externally threaded mounting member having a base defining an aperture and a tuning weight having internal threads configured to mate with the externally threaded mounting member. The aperture can be configured to receive a forward portion of a gun such that a threaded protrusion extends forward of the base. The mounting member can have a rear surface configured to abut a forward-facing shoulder of the gun. The tuning weight is rotatable about the mounting member to move in a range of axial positions with respect to the mounting member and a barrel axis. The mounting member can have a skirt extending from the base. The mounting member can have an external diameter at an externally threaded portion, and the tuning weight can have a rear portion with an internal diameter less than the external diameter of the mounting member.
