Firearm Assembly Mount for Buffer Tube Torque Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The difficulty in steadying a firearm during maintenance or assembly, particularly when torquing a castle nut, due to the challenge of securing small components in hard-to-reach places and the need for precise orientation and positioning.
Innovation Solution
A mount comprising a bottom support member, front and back pieces with buffer tube receiving openings, and a space for a rear pistol grip adapter, designed to be secured in a vise, which stabilizes the firearm by providing three secure points of contact during assembly, including the buffer tube, lower receiver, and rear pistol grip adapter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the firearm is held in a conventional manner during assembly, then the firearm can be supported, but the firearm cannot be steadily positioned in the correct orientation for maintenance or assembly operations
Solution Approach 1:
The mount is divided into multiple functional segments: a first support member for supporting the firearm, a second support member for positioning the buffer tube, and a third support member for positioning the pistol grip adapter. Each segment independently performs a specific positioning function, enabling precise orientation without requiring a complex integrated structure.
Solution Approach 2:
The mount introduces intermediary support members between the firearm components and the base structure. These intermediaries (first, second, and third support members) serve as mediators that transfer and distribute the positioning function, allowing the firearm to be steadily held in the correct orientation without direct complex constraints.
2Ease of operation
If the firearm is steadied for torquing the castle nut, then the firearm can be held steady, but the small components in hard-to-reach places remain difficult to access and manipulate
Solution Approach 1:
The mount extends positioning capability into multiple spatial dimensions by providing separate support members for different firearm components (receiver, buffer tube, pistol grip adapter). This multi-dimensional support system allows the firearm to be held steady in three-dimensional space while maintaining access to small components in hard-to-reach places.
3Device complexity
If a simple support structure is used, then the device complexity is reduced, but the firearm cannot be securely held during torquing operations requiring 40-foot pounds of torque
Solution Approach 1:
The support structure is segmented into multiple independent support members, each designed to handle specific loads. The first support member handles the primary firearm support load, while the second and third support members specifically stabilize the buffer tube and pistol grip adapter during torquing operations, distributing the 40-foot pound torque force across multiple contact points.
Solution Approach 2:
Each support member is positioned and dimensioned to provide localized support at critical points on the firearm. The second support member specifically positions the buffer tube with precision to handle torquing forces, while the third support member stabilizes the pistol grip adapter. This localized quality ensures adequate holding strength at each critical location without requiring excessive overall complexity.

AI summary
A mount for a firearm assembly, the mount being configured to be secured in another support mechanism, such as a vise. The mount comprising a bottom support member, a front piece having a front buffer tube receiving portion held by the bottom support member, and a back piece spaced apart from the front piece and having a back buffer tube receiving portion held by the bottom support member. The front piece is at the front end and the back piece is at but spaced apart from the back end. A space between the sides of the bottom support member at the back end is adapted to receive a firearm rear pistol grip adapter.
