Firearm Hand Guard Rapid Configuration System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand guard attachment systems for firearms often fail to provide adjustable angle and secure attachment, leading to loosening during use and tactile interference from external fasteners, which detract from the user experience and visual appeal.
Innovation Solution
A rapid configuration system comprising a barrel nut, jam nut, and set screws that allow for adjustable alignment and secure attachment of a hand guard to a firearm, using indexing voids and pins for rotational stability and venting, with set screws that can be tensioned to prevent rotation and removal, while being discreetly concealed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional hand guard attachment systems are used, then the hand guard can be attached to the firearm, but the attachment loosens during use and external fasteners create tactile interference
Solution Approach 1:
The patent removes external fasteners from the attachment system by integrating the securing mechanism into the hand guard itself. The hand guard includes internally threaded bores that receive set screws, eliminating the need for external fastening components that would create tactile interference while maintaining secure attachment during use.
Solution Approach 2:
The set screws are nested within the hand guard structure, with the hand guard's internally threaded bores receiving the set screws. This nesting approach allows the securing mechanism to be concealed within the hand guard's own structure, providing secure attachment without external visible fasteners.
2Manufacturing precision
If adjustable angle attachment is implemented, then alignment precision is improved, but device complexity increases
Solution Approach 1:
The patent implements adjustability by allowing the hand guard to be rotated to different angular positions and secured at each position using the set screws. The hand guard can be dynamically adjusted to various angles relative to the barrel axis and then locked in place, providing alignment precision without requiring a complex multi-component adjustment mechanism.

AI summary
Disclosed is a hand guard attachment system. The system in one form comprising a barrel nut affixed to an upper receiver of the firearm and a jam nut each with a threaded outer surface aligned with and co-axial to a bore of the firearm. The rapid configuration system may include a plurality of indexing pins aligned with, but not coaxial to the bore of the firearm. The hand guard may include an inner threaded surface where the threads cooperate with the threads of the jam nut and barrel nut. A method for attachment of the hand guard to the firearm is also disclosed. The method in one form including the steps of: threading the hand guard onto the jam nut and barrel nut; and tensioning the set screws. The method may include a step where the set screws are adjusted to manipulate the angle of the hand guard relative to the bore.
