Firearm Hand Guard Free Float Mounting System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hand guards for firearms can impair accuracy due to torque-induced effects and lack suitable support, failing to adequately protect users and mount accessories effectively.
Innovation Solution
A system comprising a hand guard and accessory mounting device that includes a bolt up plate, barrel nut, and rail-shaped components, allowing the hand guard to 'free float' around the barrel, with quick disconnect thumbscrews for accessory mounting, suitable for rifles like M-16, AR-15, and M4 types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional hand guard is used to protect the user from injuries, then user protection is improved, but the torque caused by user grip adversely affects aim and accuracy
Solution Approach 1:
The hand guard is divided into multiple separate hand guard pieces rather than a single continuous structure. These segments are positioned around the barrel and connected through a U-shaped yoke, allowing the hand to grip the firearm without directly contacting the barrel while minimizing torque transmission to the barrel.
Solution Approach 2:
A U-shaped yoke acts as an intermediary structure that connects the hand guard pieces to the barrel nut. The yoke provides a mounting structure that allows the hand guard pieces to be positioned around the barrel while being secured to the firearm's existing barrel nut, thereby protecting the user without compromising accuracy.
2Ease of manufacture
If a U-shaped yoke is used to engage the barrel nut, then assembly is simplified, but the hand guard pieces lack suitable support
Solution Approach 1:
The U-shaped yoke is designed to perform multiple functions: it serves as both the mounting structure for the hand guard pieces and as a connector to the existing barrel nut. By utilizing the existing barrel nut as a mounting point, the yoke provides adequate support for the hand guard pieces while maintaining assembly simplicity.
3Object-affected harmful factors
If conventional hand guard pieces are used, then user protection is provided, but accessory mounting capability is lacking
Solution Approach 1:
The hand guard system is designed to perform multiple functions: it provides protection to the user's hand from heat and injury, maintains firearm accuracy by minimizing torque, and serves as a mounting structure for accessories. The U-shaped yoke and hand guard pieces are configured to accommodate additional components while preserving their primary protective function.

AI summary
A system for providing a hand guard and accessory mounting device for a firearm can include at least one barrel nut, at least one bolt up plate, at least one hand guard, and at least one mounting device. The at least one barrel nut can be adapted to mount to a portion of a barrel associated with a firearm. The at least one bolt up plate can be adapted to mount between the at least one barrel nut and a portion of the firearm. The at least one hand guard can be adapted to mount to a portion of the bolt up plate, substantially concentric with a portion of the barrel. The at least one mounting device can be adapted to mount to the at least one hand guard, the mounting device being further adapted to receive at least one firearm accessory.
