Multi-Caliber Firearm Zeroing Target With Laser Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm zeroing processes are labor-intensive and require extensive live fire adjustments, especially when dealing with multiple weapons of varying calibers, and often lack access to suitable ranges for proper bore-sighting.
Innovation Solution
A zeroing target system comprising a range card insert with zero range and caliber markings, and a range card sleeve with viewing windows, allowing for quick alignment of the point of aim indicator with the point of impact indicator using a laser boresight, facilitating rapid and accurate bore-sighting across multiple calibers and ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional zeroing methods are used with multiple firearms of varying calibers, then each firearm requires separate bore-sighting equipment and targets, but this increases device complexity and time consumption
Solution Approach 1:
The range card sleeve is designed to accommodate multiple range card inserts for different calibers (5.56mm, 7.62mm, .308, .50 cal) within a single device. The universal sleeve structure with standardized viewing windows and laser alignment features allows one bore-sighting system to serve multiple firearm calibers, eliminating the need for separate equipment for each caliber.
Solution Approach 2:
Multiple range card inserts are nested within a single range card sleeve. Each insert contains caliber-specific markings and data, while the sleeve provides the common structural framework, viewing windows, and laser alignment features. This nesting approach consolidates multiple caliber-specific targets into one integrated device.
2Measurement precision
If traditional zeroing processes are used for multiple firearms, then extensive live fire adjustments are required for each weapon, but this increases loss of time and live ammunition consumption
Solution Approach 1:
The range card inserts contain pre-calculated zeroing data and markings for various ranges and calibers. Users can perform preliminary bore-sighting with a laser boresight aligned through the viewing windows, establishing an initial zero without firing any rounds. This preliminary alignment eliminates the need for extensive live fire adjustments, saving time and ammunition.
Solution Approach 2:
The system replaces the traditional mechanical trial-and-error zeroing process (firing rounds and adjusting sights) with an optical alignment system. The laser boresight projects a visible point through the range card sleeve, allowing users to visually align the sight picture with the point of impact indicator before firing, thereby substituting optical precision for mechanical adjustment iterations.
3Ease of operation
If conventional bore-sighting targets are used, then users lack clear visual indicators for alignment, but this worsens measurement precision and increases difficulty of detecting and measuring
Solution Approach 1:
The range card inserts feature distinct colored markings including a red point of impact indicator and green point of aim indicator. These color-coded visual elements provide immediate, intuitive feedback for alignment status, making it easy for users to identify whether the sight picture is correctly aligned with the intended point of impact.
Solution Approach 2:
The range card sleeve acts as an intermediary optical device between the laser boresight and the firearm sights. It provides a standardized interface with viewing windows that allow the laser point to be visually correlated with printed indicators, mediating the alignment process between the boresight tool and the firearm's sighting system.

AI summary
Provided is a zeroing target for a firearm sighting system that includes a range card insert and a range card sleeve. The range card insert includes zero range increment markings, caliber markings, and a point of aim indicator. The range card sleeve includes a zero range viewing window, a caliber viewing window, a point of aim viewing window, and a point of impact indicator. The range card insert fits within the range card sleeve and can be moved upwards or downwards within the sleeve for selecting a desired zero range increment marking and caliber marking. A laser boresight is aimed at the point of impact indicator and a sighting system on the weapon is adjusted until the sighting system is pointing at the point of aim indicator. When the two values align, the weapon is properly bore-sighted for the desired caliber and range, which can then be confirmed by live fire.
