Enclosed Reflex Sight With Rear Adjustment for Standard Co-Witnessing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing enclosed reflex sights for firearms often require enlarged housings due to elevation adjustment mechanisms, leading to a raised optical center that prevents co-witnessing with standard height iron sights, necessitating the replacement of these sights with taller aftermarket alternatives.
Innovation Solution
The enclosed reflex sight assembly features a rearward bottom portion housing the adjustment assembly, with the lowermost surface closer to the firearm's mounting surface than the upper surface, allowing for a compact design that co-witnesses with standard height iron sights without requiring taller replacements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the housing is enlarged to accommodate the elevation adjustment mechanism, then the adjustment functionality is improved, but the optical center is raised and co-witnessing with standard height iron sights is prevented
Solution Approach 1:
The patent repositions the elevation adjustment mechanism from a vertical arrangement (which raises the optical center) to a horizontal arrangement at the rear of the housing. This dimensional change allows the adjustment mechanism to be accommodated without increasing the housing height, thereby maintaining co-witnessing capability with standard iron sights while preserving elevation adjustment functionality.
Solution Approach 2:
The housing is divided into distinct functional zones: the optical assembly section, the rearward bottom portion containing the adjustment mechanism, and the mounting interface section. This segmentation allows each component to be optimized independently, positioning the adjustment mechanism in a location that does not interfere with the optical center height required for co-witnessing.
2Ease of operation
If the housing is enlarged to accommodate the elevation adjustment mechanism, then the adjustment functionality is improved, but taller aftermarket iron sights are required
Solution Approach 1:
By moving the elevation adjustment mechanism to a horizontal orientation at the rear of the housing rather than a vertical arrangement, the patent eliminates the need for taller aftermarket iron sights. The optical center remains at the correct height for co-witnessing with standard iron sights while the adjustment mechanism is accommodated in the rearward bottom portion of the housing.
3Ease of operation
If the mounting interface is positioned forward of the rear sight, then the reflex sight is properly positioned on the firearm, but the housing must accommodate the adjustment mechanism which raises the optical center
Solution Approach 1:
The housing is segmented into functional portions: the mounting interface section positioned forward of the rear sight, the optical assembly section, and the rearward bottom portion containing the adjustment mechanism. This segmentation allows the mounting interface to be positioned optimally for firearm attachment while the adjustment mechanism is contained in a separate rearward section that does not increase the overall housing height.
Solution Approach 2:
The adjustment mechanism is arranged horizontally in the rearward bottom portion rather than vertically, changing the spatial dimension in which the mechanism operates. This allows the housing to maintain a compact height suitable for co-witnessing while accommodating the adjustment functionality.

AI summary
The disclosure is related to an enclosed reflex sight for one or more firearms. The enclosed reflex sight may be provided as part of an assembly including a mounting interface. The enclosed reflex sight includes a rearward bottom portion that houses an adjustment assembly, wherein the rearward bottom portion includes a lowermost surface of the enclosed reflex sight. The enclosed reflex sight includes an upper bottom surface forward of the rearward bottom portion of the enclosed reflex sight, the upper bottom surface comprising an abutment surface for the mounting interface. When the assembly is secured to an upper mounting surface of a firearm then the lowermost surface of the rearward bottom portion of the enclosed reflex sight is closer to the upper mounting surface of the firearm than the upper bottom surface of the enclosed reflex sight.
