Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rifle sportsmen often need multiple guns to accommodate different types and calibers, which is inconvenient and costly.
Innovation Solution
A bolt action upper receiver assembly that can be coupled with a standard AR lower receiver, allowing conversion of an AR rifle into a bolt action rifle, featuring a unitary bolt body with specific geometries and features for efficient operation and safety mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple guns are purchased to accommodate different types and calibers, then shooting versatility is improved, but cost and equipment complexity increase
Solution Approach 1:
The bolt action upper receiver assembly is designed to be universally compatible with standard AR lower receivers, allowing a single platform to perform multiple functions. The receiver includes standardized features such as a Picatinny rail for various optics, a magazine well accepting different magazine types, and a barrel thread pattern that accommodates multiple calibers, enabling one gun to replace multiple specialized firearms
2Adaptability or versatility
If multiple guns are purchased to accommodate different types and calibers, then shooting versatility is improved, but cost increases
Solution Approach 1:
The bolt action upper receiver assembly serves as a universal platform that can be configured for different calibers and shooting disciplines. By maintaining compatibility with standard AR lower receivers and accessories, the design allows shooters to invest in one upper receiver and interchange barrels and lower receivers as needed, significantly reducing the total cost compared to purchasing multiple dedicated firearms
3Adaptability or versatility
If a bolt action mechanism is integrated into an AR platform, then shooting type flexibility is improved, but device complexity increases
Solution Approach 1:
The firearm is divided into separable modules: a bolt action upper receiver assembly that can be detached from and reattached to different AR lower receivers. This segmentation allows the complex bolt action mechanism to be isolated in the upper receiver, while the lower receiver maintains the familiar AR interface, distributing complexity across manageable components rather than integrating everything into a single complex system

AI summary
A bolt action AR rifle can be prepared using a standard AR lower assembly and coupling it to a bolt action upper assembly. The bolt action upper assembly has a bolt action receiver containing a bolt. The method of forming a bolt action AR rifle can include: providing the bolt action upper receiver assembly; providing the standard AR lower AR receiver assembly having a pivot pin and takedown pin; inserting the pivot pin into the pivot pin receiver hole; pivoting the bolt action upper receiver assembly at the pivot pin until the takedown pin is aligned with the takedown pin receiver hole; and inserting the takedown pin into the takedown pin receiver hole.
