Modular Rifle Bipod Leg Attachment for Stable Quick Release

The support part has a non-circular cross-section (e.g., D-shaped, oval, or polygonal) that corresponds to a non-circular recess in the leg fastening part. This asymmetric geometry prevents rotational movement of the support part within the recess, ensuring that the threaded engagement maintains a fixed orientation and prevents the leg from rotating or becoming loose during use, thereby improving attachment reliability without requiring additional locking mechanisms

The mushroom-shaped support part features a rounded, domed top surface that provides a large bearing area for distributing loads. This curved geometry naturally resists upward forces attempting to disengage the leg, while the threaded stem portion provides precise angular control during assembly. The combination of the curved head and threaded stem creates a self-centering effect that guides proper insertion and engagement, improving reliability while keeping the mechanism simple

The bipod is divided into modular components: a main body, detachable leg parts, and intermediate support parts that can be independently manufactured and assembled. The leg parts can be quickly attached or detached by simply inserting the support part into the leg fastening part and rotating to engage the threaded connection. This segmentation allows users to maintain or replace individual components without affecting the entire bipod system, improving ease of operation while managing complexity through standardization of interfaces

The threaded engagement mechanism is designed to be self-aligning and self-securing. The non-circular cross-section automatically orients the support part correctly as it is inserted into the leg fastening part, eliminating the need for alignment marks or complex positioning procedures. The threading itself provides both the attachment function and the locking function, so no separate locking step is required. Users can attach or detach legs with a simple rotational motion, making the operation intuitive and requiring minimal training

The non-circular cross-section (such as D-shaped, oval, or hexagonal) provides inherent rotational stability because the asymmetric geometry only fits in one orientation within the corresponding recess. This eliminates the need for high-precision machining of flat surfaces or complex locking features. The tolerance requirements are reduced to simple dimensional fits, as the asymmetric shape itself provides the orientation constraint, making manufacturing more forgiving while maintaining stable leg orientation

The mushroom-shaped support part with its rounded head and curved surfaces is easier to manufacture with standard machining or forming processes compared to precise flat surfaces or angular features. The curved geometry naturally guides assembly through a self-centering effect, reducing the need for extremely tight tolerances. The rounding of corners and edges in the non-circular cross-section further simplifies manufacturing by avoiding sharp corners that would require precise tool positioning, while still maintaining sufficient geometric distinction to prevent rotation
