GDM® Direct Thread Mount
The GDM® Direct Thread Mount is part of the GDM® modular mounting ecosystem — engineered to provide a simple, secure, and repeatable suppressor interface without the complexity of quick-detach systems.
Designed to thread directly onto the host barrel and interface with all HUB-compatible GDM® suppressors, this mount offers a streamlined solution for shooters who prioritize alignment consistency, minimal added length, and long-term reliability.
Precision Alignment & Accuracy
The firm, direct-thread connection between the suppressor and barrel minimizes tolerance stacking and movement, resulting in improved concentricity and alignment.
This typically translates to enhanced accuracy compared to quick-detach systems, making the GDM® Direct Thread Mount an ideal choice for precision rifle applications.
Modularity & Compatibility
Featuring the industry-standard HUB interface (1.375×24), the GDM® Direct Thread Mount integrates seamlessly with all GDM® HUB suppressors and other HUB-compatible systems.
Multiple thread pitch options allow it to support a wide range of host platforms without locking you into proprietary hardware.
This mount is also well-suited for Form 1 builders and users seeking a lightweight, affordable direct-thread solution for modular suppressor systems.
