Firearm Vise Block with Adjustable Magwell Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm vise blocks often have an imprecise fit between the block and the ammunition magazine well, leading to insecure support during maintenance tasks.
Innovation Solution
A firearm vise block with an adjustable second side that can move between an insertion state and an expanded state, secured via an adjustment mechanism including a wedge, threaded post, and adjustment handle, allowing for secure fitting within the magwell by expanding contacting portions to engage with the magwell surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing vise blocks are used with a fixed fit design, then the device structure is simple, but the fit between block and magwell is imprecise leading to insecure support
Solution Approach 1:
The vise block employs a dynamic adjustment mechanism where the second side can move between insertion and expansion states. The contacting portions are made resilient and can be selectively positioned to expand outwardly, transforming a static structure into a dynamic one that adapts to different magwell dimensions, thereby achieving precise fit and secure support
Solution Approach 2:
The invention changes the physical state and position parameters of the contacting portions through the adjustment mechanism. By moving the second side between insertion and expansion states, and by expanding the contacting portions outwardly, the block adapts its dimensional parameters to match varying magwell specifications, resolving the fit precision issue
2Manufacturing precision
If the second side is made adjustable between insertion and expanded states, then the fit precision is improved, but the device complexity increases
Solution Approach 1:
The vise block is segmented into distinct functional components: a block body, a movable second side with contacting portions, and an adjustment mechanism. This segmentation allows each component to be optimized independently - the contacting portions can be made resilient for precision fit, while the adjustment mechanism provides controlled movement, achieving high fit precision without excessive overall complexity
3Reliability
If contacting portions are expanded to engage magwell surfaces, then secure attachment is achieved, but the operation becomes more complex
Solution Approach 1:
The adjustment mechanism is designed to enable the operator to manually expand the contacting portions to the required state, after which the mechanism maintains the expanded position through its mechanical design (resilient contacting portions pressing against magwell surfaces). This self-locking characteristic allows hands-free operation during maintenance tasks, as the block remains securely attached without continuous manual intervention
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Provides a secure and stable support for firearms during maintenance, eliminating free play and ensuring the vise block remains attached, even when the magazine lock is engaged, allowing for hands-free operation and improved precision.
Implementation Method 1
The adjustment mechanism can include a wedge structured and configured to move the second side between the insertion state and the expanded state
Implementation Method 2
The adjustment mechanism can include a threaded post and an adjustment handle coupled to the threaded post
Implementation Method 3
The block body can be formed from a resilient material

AI summary
A firearm vise block can include a block body and an adjustment mechanism. The block body can include a first side structured and configured to be clamped between jaws of a bench vise, and a second side can be structured and configured to fit within an ammunition magazine well of a firearm. The second side can be adjustable between at least an insertion state and an expanded state. The adjustment mechanism can be structured and configured to selectively and reversibly move the second side between the insertion state and the expanded state.
