Rear Sight Assembly With Aligned Flanges for Back-Mounted Optics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rear sights on firearms interfere with the installation of optic mounts at the back of the slide, leading to decreased accuracy and holster compatibility, and existing solutions either require customization or increase bulkiness.
Innovation Solution
A rear sight assembly that allows the optic mount to be positioned further back on the slide by using a notch component with flanges and apertures that align with mounting holes, maintaining distance from the front sight for accuracy and reducing bulk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the optic mount is positioned at the back of the slide for improved holster compatibility, then holster compatibility is improved, but the conventional rear sight prevents installation at this position
Solution Approach 1:
The rear sight assembly is segmented into a rear sight component and a base portion with flanges and apertures. The base portion attaches to the optic mount while the rear sight component provides the sighting function, allowing separate optimization of each component's position and function.
Solution Approach 2:
The base portion with flanges and apertures acts as an intermediary component between the conventional rear sight mounting system and the optic mount. This intermediary enables the rear sight to be positioned at the back of the slide while maintaining compatibility with standard rear sight mounting holes.
2Ease of manufacture
If the rear sight is positioned in front of the optic mount, then installation is possible, but the distance between rear sight and front sight decreases reducing accuracy
Solution Approach 1:
The rear sight assembly extends in the longitudinal dimension of the firearm by positioning the base portion at the rear of the slide with the rear sight component extending forward. This dimensional arrangement maintains adequate distance between the rear sight and front sight while enabling installation at the optimal rear position for holster compatibility.
3Ease of manufacture
If the rotatable rear sight is coupled to the end of the optic mount, then installation is possible, but the rear sight extends off the slide increasing bulkiness
Solution Approach 1:
Instead of extending the rear sight forward from the optic mount end, the base portion is positioned at the rear of the slide with flanges extending toward the front to engage with mounting holes. This inverted arrangement keeps the rear sight within the slide boundaries, reducing bulkiness while maintaining installation capability.
4Adaptability or versatility
If the optic mount is positioned further back on the slide, then holster compatibility and accuracy are improved, but the rear sight must be repositioned
Solution Approach 1:
The base portion with flanges and apertures provides universal compatibility with standard optic mount locations. The flanges can engage with mounting holes at various positions on the slide, allowing the same rear sight assembly to accommodate different optic mount positions while maintaining proper rear sight alignment and function.
Data Source
AI summary
A rear sight and related assembly are disclosed. The rear sight has a notch component coupled to a base portion. The notch component includes a notch forming a channel through the notch component, the channel having a channel direction. The base portion has a first flange having a first aperture and a second flange having a second aperture couple coupling with an optic mount. The assembly of the rear sight includes the rear sight coupled to the optic mount. The apertures of the rear sight are configured to concentrically align with mounting holes of the optic mount. The optic mount is configured to couple to a slide of a firearm.
