Diligent Defense Zilch Titanium QD HUB Mount

The Diligent Defense Zilch titanium QD HUB mount is the titanium-construction quick-detach mount for the Zilch series of suppressors, built on the industry-standard HUB (Hybrid Universal Back) mounting interface. If you run Dead Air, SilencerCo, Q, or other HUB-compatible cans, this mount extends Zilch compatibility across your entire inventory.

Machined from grade-5 titanium — substantially lighter than stainless steel with no sacrifice in strength or thermal performance. The HUB threaded interface (1.375x24) is the same industry-standard adopter fitting used across the majority of modern rifle suppressors, meaning one can with this mount covers multiple hosts. The QD engagement is positive, repeatable, and indexes to the timing shoulder without slop.

Rated for full-auto and magnum rifle calibers within the Zilch suppressor envelope. Installation is straightforward: thread onto the suppressor body, torque to spec, mount to any HUB-compatible muzzle device or direct-thread adapter on the host rifle. Ideal for shooters running a single Zilch across multiple builds — an M4A1, a bolt gun, and a precision .308 gas gun with one can.
