Precision Bore Guide Tool Caliber-Specific Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Contemporary bore guides for firearms have a universal fit design that leads to debris accumulation in the rifle's chamber and throat during cleaning, damaging the firearm and reducing accuracy, and can also cause damage to the throat and lands due to movement during use.
Innovation Solution
A precision bore guide tool with a main tube, front stop, movable stop, and spring, or a hollowed-out rifle round design that provides a custom fit per caliber, ensuring the bore guide stays in place and prevents debris from entering the rifle's action, chamber, shoulder, neck, and throat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a universal fit bore guide design is used, then the bore guide can accommodate different calibers, but debris accumulates in the chamber and throat causing damage and reduced accuracy
Solution Approach 1:
The patent applies local quality by creating a bore guide with caliber-specific dimensions rather than a universal fit. Each bore guide is precisely engineered to match the specific caliber's chamber, shoulder, neck, and throat dimensions, ensuring a custom fit that prevents debris accumulation in critical areas while maintaining adaptability through a line of caliber-specific variants.
Solution Approach 2:
The invention segments the bore guide into distinct functional zones with specific dimensions: a front portion matching the chamber dimensions, a middle portion matching the shoulder and neck, and a rear portion matching the throat. This segmentation allows each zone to perform its specific function of preventing debris accumulation in the corresponding area.
2Adaptability or versatility
If a universal fit bore guide design is used, then the bore guide can be used for multiple calibers, but the bore guide moves during cleaning risking damage to the throat and lands
Solution Approach 1:
The patent ensures position stability through local quality by designing the bore guide with caliber-specific dimensions that match the exact geometry of the firearm's chamber, shoulder, neck, and throat. This precise local matching prevents movement during cleaning operations, ensuring the bore guide remains reliably positioned throughout the cleaning process.
3Object-affected harmful factors
If a custom fit per caliber bore guide is used, then debris is prevented from entering critical areas, but the device complexity increases
Solution Approach 1:
The patent manages device complexity through segmentation by dividing the bore guide into standardized functional zones (chamber portion, shoulder portion, neck portion, throat portion), each with specific dimensional requirements. While each caliber requires a custom guide, the segmented structure allows for systematic manufacturing and reduces the complexity of designing and producing each caliber-specific variant.

Function Achieved in This Case
The precision bore guide tool effectively and safely cleans the firearm by preventing debris from entering critical areas, maintaining rifle accuracy and precision, and protecting the throat and lands from damage.
Implementation Method 1
a spring, and the spring is disposed around the outer circumference of the main tube, and the spring is disposed between the front stop and the movable stop
