Introducing HUB-LOK™
The Suppressor-Centric Hard-Mount Interface by Quiet Labs
Patent Pending
Quiet Labs is proud to introduce HUB-LOK™ — a patent-pending, precision-engineered suppressor adapter system designed around a suppressor-first philosophy.
HUB-LOK™ is built to stay with the suppressor.
The adapter (Plan-B & HUB compatible - 1.375x24) and attached accessories remain mounted to the suppressor itself as it moves between firearms. There is no need to remove, re-index, or re-configure accessories when changing hosts. Alignment, fitment, and overall configuration remain consistent regardless of which rifle the suppressor is mounted to.
This design allows the suppressor, adapter, and accessories to function as a single, repeatable, self-contained system.
A Rigid, Repeatable Interface
HUB-LOK™ creates a hard-mount accessory interface that allows suppressor-mounted accessories to attach directly to the adapter via a six-screw mechanical lockup. The result is a stable, repeatable mounting solution designed for consistency and durability.
The HUB-LOK™ interface supports Quiet Labs accessories and licensed third-party accessories specifically designed to interface with the HUB-LOK™ adapter.
Launch Configuration & Compatibility
HUB-LOK™ will launch as a Plan B–compatible suppressor adapter, enabling immediate integration with one of the most widely adopted mounting standards in the industry. Additional mounting standards and adapter configurations are already in development and will follow.
At launch, Quiet Labs will offer SURG-Style shrouds in suppressor-specific lengths, designed to match the most common suppressors on the market. Multiple cage designs are already in development and will follow after launch.
HUB-LOK™ Cage Benefits
The HUB-LOK™ cage shroud is designed to deliver practical protection without compromising alignment or usability.
- Protects the suppressor
- Helps to mitigate contact burns for the user and surrounding gear
- Maintains a rigid, suppressor-mounted interface
- Designed to move with the suppressor between hosts
- Acts as a heat sink, cooling off your suppressor faster
- Additional cage and shroud designs planned following launch
Cages will be available in Black and Flat Dark Earth (FDE).

Precision Is Not Assumed. It’s Proven.
At Quiet Labs, concentricity is not a marketing claim—it is a requirement.
Every HUB-LOK™ adapter undergoes a documented alignment verification process prior to shipment. Each unit is checked for concentricity using:
-
A known-good barrel
-
A known-good muzzle device
-
A known-good suppressor
-
A precision alignment rod
Each adapter ships with a time-stamped photograph showing the exact moment alignment was verified. This ensures every HUB-LOK™ leaving our facility meets the same standards we demand for our own equipment.
No batch assumptions. No sampling. Every unit verified.
The Quiet Labs Standard
HUB-LOK™ reflects what Quiet Labs stands for:
-
Suppressor-centric design
-
Innovation driven by real-world use
-
Precision that is validated, not assumed
-
Quality control that protects the end user’s investment
HUB-LOK™ is engineered to remain with the suppressor, maintain alignment, and deliver consistent performance across platforms.
