Detachable Chassis Base for Tactical Rifle Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The maintenance of sniper rifles is inefficient due to the lengthy process of removing the barreled action, which disrupts the established zero of the weapon and optics, causing unnecessary wear and affecting accuracy, and requires re-establishment of zero upon reassembly.
Innovation Solution
A detachable chassis base for tactical rifles that allows selective attachment and removal, providing access to the trigger mechanism and magazine well for maintenance without disturbing the barreled action, featuring a flared magazine well assembly, magazine catch, and trigger guard, and can be completely removable or hingedly attached for modular compatibility with various calibers and magazine types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the barreled action is removed for maintenance, then access to the trigger mechanism is improved, but the established zero of the weapon and optics is disrupted causing accuracy degradation
Solution Approach 1:
The chassis base is segmented as a separate removable component from the barreled action. The chassis base includes the trigger guard, magazine well, and forward handguard, while the barreled action remains attached to the receiver. This segmentation allows the chassis base to be removed for maintenance without disturbing the barreled action and optical zeroing.
Solution Approach 2:
The chassis base is extracted as a distinct removable module that houses the trigger mechanism. By taking out only the necessary components (trigger guard, magazine well) from the overall assembly, maintenance can be performed on the trigger mechanism without removing the barreled action, thus preserving the established zero.
2Ease of repair
If the barreled action is removed for maintenance, then access to the trigger mechanism is improved, but unnecessary wear is caused to the weapon components
Solution Approach 1:
The chassis base is segmented as a separate removable component that contains the trigger mechanism. This segmentation allows maintenance personnel to access and service the trigger mechanism by removing only the lightweight chassis base rather than the entire barreled action, significantly reducing mechanical stress and wear on the weapon's critical components.
3Ease of repair
If the chassis base is made completely removable, then maintenance access is improved, but device complexity increases
Solution Approach 1:
The chassis base is designed as a segmented removable module that can be detached from the receiver via a latch mechanism. This segmentation provides excellent maintenance access while keeping the modular interface simple and intuitive, avoiding excessive complexity.
Solution Approach 2:
The chassis base incorporates a user-friendly latch mechanism that allows field personnel to quickly release and remove the chassis base without requiring tools or complex procedures. The self-service design simplifies the removal process while maintaining secure attachment during normal operation.

AI summary
A detachable chassis base for a tactical rifle is presented. The lower chassis receiver assembly can have a detachable chassis base that substantially selectively attaches to the chassis receiver interface. The detachable chassis base can be completely removable, or it can be hingedly attached to provide access without completely removing the chassis base, or a combination thereof. Multiple combinations of parts included in the detachable chassis base are possible. Several variations and combinations are illustrated herein, although others are contemplated.
