Off-set Cantilever Weapon Sights for Rapid Sight Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Combatants face challenges in engaging targets at varying ranges with rifles, as optical sights are superior at longer ranges but can obstruct iron sights, requiring removal for backup use, and transitions between optical and iron sights can be problematic.
Innovation Solution
The development of off-set weapon sights that mount to the same accessory rail as optical sights, featuring a cantilevered and angular configuration allowing quick transitions between optical and iron sight use by canting the weapon, eliminating field obstruction and enabling effective engagement at both long and short ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an optical sight is mounted on the weapon accessory rail, then long-range targeting capability is improved, but the iron sights are obstructed and cannot be used
Solution Approach 1:
The iron sights are positioned in a lateral dimension offset from the optical sight's optical axis, allowing both sights to coexist on the same accessory rail without obstruction. The offset mounting base extends perpendicular to the rail, placing the iron sight elements in a different spatial plane than the optical sight.
2Measurement precision
If an optical sight is mounted on the weapon accessory rail, then long-range targeting capability is improved, but transitions to iron sights become problematic
Solution Approach 1:
The iron sights are pre-positioned in an offset configuration that allows immediate use by simply canting the weapon, eliminating the need for time-consuming removal or reconfiguration of the optical sight. The backup sight is prepared in advance in a position that requires only a body movement to access.
3Measurement precision
If an optical sight is mounted on the weapon accessory rail, then long-range targeting capability is improved, but a front sight shadow appears on the optical image
Solution Approach 1:
The iron sight front post is extracted from the traditional position directly in the optical path and relocated to an offset position lateral to the optical sight. This removes the source of the shadow problem while preserving the iron sight functionality for close-range engagements.
4Measurement precision
If separate rifle sighting systems are used for varying ranges, then targeting effectiveness at different ranges is improved, but device complexity increases
Solution Approach 1:
The optical sight and iron sights are merged into a single integrated sighting system mounted on one accessory rail. Both sighting systems share the same mounting interface and coexist in close proximity, eliminating the need for separate mounting rails or multiple independent sighting systems.

AI summary
The weapon sights can be used simultaneously in conjunction with another optical sight and can be mounted on the same weapon accessory rail as the other optical sight. The weapon sights include a front sight and a rear sight that detachably mount to the weapon's accessory rail, but are cantilevered and off-set so that they do not interfere with the optical sight mounted to the same accessory rail. The cantilevered configuration and off-set orientation of the rear sight assembly and the front sight post also allow the shooter to transition quickly between the weapon sight of this invention and an optical sight by simply canting the weapon 45 degrees to bring the desired sight on target and into the vertical of the weapon.
