Dual Reflector Sight System for Quick-Change Barrel Firearms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The accuracy of firearms with quick-change barrel capabilities is compromised due to different barrel configurations producing distinct grouping patterns, leading to inconsistent aim points when switching between barrels or ammunition types, which is time-consuming to adjust and requires shooting range testing.
Innovation Solution
A dual-reflector sight system mounted on a adjustable sight mount that allows for alignment and calibration of two reticles, enabling accurate shooting across different barrel setups or ammunition types by compensating for varying shooting distances and ballistic properties, with a tubular seal to protect the optics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single reflector sight is used on a firearm with quick-change barrel capability, then the device complexity is low, but the accuracy deteriorates when switching between different barrels or ammunition types due to different grouping patterns
Solution Approach 1:
The sight system is segmented into multiple independent reflector sights (first reflector sight and second reflector sight), each calibrated for different barrel configurations or ammunition types. This allows the shooter to select the appropriate sight segment for the current configuration, maintaining accuracy without requiring a complete sight adjustment process.
Solution Approach 2:
The sight mount is designed to accommodate multiple reflector sights with different reticle calibrations, making the sight system universal for different barrel setups and ammunition types. The same mount can hold various sights calibrated for different ballistic characteristics, eliminating the need for multiple separate sight systems.
2Measurement precision
If the shooter resets the sights after each barrel change to maintain accuracy, then the shooting accuracy is maintained, but the time consumption increases due to test shooting and adjustment requirements
Solution Approach 1:
Multiple reflector sights are pre-calibrated during manufacturing or initial setup for different barrel configurations and ammunition types. This preliminary calibration eliminates the need for time-consuming field adjustments when changing barrels, as the shooter can simply switch to the pre-configured sight corresponding to the current setup.
Solution Approach 2:
The sight selection mechanism is merged with the barrel change process. The sight system is integrated into the firearm platform such that changing between different reflector sights can be done quickly alongside barrel changes, combining two operations that were previously separate and time-consuming.
3Adaptability or versatility
If multiple reflector sights are mounted on the sight mount to compensate for different barrel setups, then the adaptability improves for different configurations, but the device complexity increases
Solution Approach 1:
A single universal sight mount is designed to accommodate multiple types of reflector sights with different reticle calibrations. This universal interface allows the system to adapt to different barrel configurations and ammunition types while maintaining a relatively simple and unified mounting structure, rather than requiring separate mounting systems for each sight type.

AI summary
A sight system (10) for a firearm (12) is proposed. The sight system comprises: a sight mount (14) configured to be attached to the firearm (12), a first reflector sight (16) mounted on the sight mount (14) and producing a first aim point/image, and a second reflector sight (18) mounted on the sight mount (14) and producing a second aim point/image. The second reflector sight (18) is positioned in front of and aligned with the first reflector sight (16), and the first aim point/image and the second aim point/image are visible through the first reflector sight (16). The firearm (12) has a first mode of operation and a second mode of operation, and: the first reflector sight (16) is calibrated with respect to the first mode of operation, and the second reflector sight (18) is calibrated with respect to the second mode of operation.
