AR-15 Shotgun Conversion Kit With Split Receiver And Adjustable Gas Block
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm modifications do not allow for seamless conversion of AR-15 rifles to fire shotgun shells while maintaining ease of use and precision, as they lack adaptable gas systems and interchangeable barrels.
Innovation Solution
A shotgun conversion system for AR-15 rifles featuring a longitudinally split receiver, adjustable gas block assembly, and slide-in interchangeable barrels, along with a stock adapter and magazine release mechanism designed for ergonomic operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If AR-15 rifles are modified to fire shotgun shells, then versatility is improved, but device complexity increases
Solution Approach 1:
The receiver is divided into two separate components: a standard AR-15 receiver and a separate shotgun conversion kit. This segmentation allows the rifle to be converted to shotgun configuration without permanently modifying the original receiver, thereby improving versatility while managing complexity through modular design.
Solution Approach 2:
The conversion kit is designed to work with standard AR-15 receivers, making the system universal. The kit includes interchangeable barrels and gas blocks that can be attached to the receiver, allowing the same base platform to function as both a rifle and shotgun depending on the attached components.
2Adaptability or versatility
If interchangeable barrels are implemented, then adaptability is improved, but device complexity increases
Solution Approach 1:
The barrel system is segmented into interchangeable barrels with a standardized mounting interface. Each barrel can be independently attached or detached from the receiver using the same mounting mechanism, enabling easy customization while maintaining a relatively simple overall structure through standardization.
3Adaptability or versatility
If adjustable gas block assembly is added, then adaptability is improved, but device complexity increases
Solution Approach 1:
The gas block assembly is designed to be adjustable rather than fixed, allowing dynamic modification of gas volume and pressure characteristics. This enables optimization for different shotgun shell types and firing conditions while maintaining a manageable complexity level through a straightforward adjustment mechanism.

AI summary
Disclosed herein are modifications to a firearm of the assault (tactical) weapon style which allow those familiar with these sorts of rifles, especially the AR-15, and AR-15 variant rifles, to rapidly gain comfort and precision with a shotgun of the semi-automatic or potentially automatic feed mechanism in that the disclosed shotgun is externally the same and substantially identical externally to the assault weapon to which they are already familiar. In particular, the disclosed shotgun has a receiver, pistol style grip, hand guard, magazine receiver, and stock adapter which is substantially identical to an AR-15 or AAR-15 variant rifle to which they are already accustomed.
