A Complete Guide for Suppressor Owners

A thread adapter for firearms is a critical mounting component that allows a suppressor to securely attach to a firearm barrel when the thread patterns differ or when a specific mounting style is preferred. For shooters running suppressors—whether for hunting, tactical use, or range shooting—a quality thread adapter ensures proper alignment, consistent accuracy, and reliable performance.

Thread adapters are most commonly used with direct thread suppressor mounting systems, where the suppressor threads directly onto the barrel rather than relying on a quick-detach (QD) muzzle device. This approach is favored by many shooters for its simplicity, reduced weight, and improved point-of-impact (POI) consistency.

Our team at Next Level Armament is going to break it down.

Why Use a Direct Thread Adapter?

A direct thread adapter offers several advantages over QD mounting systems:

• Improved POI consistency with fewer moving parts

• Reduced overall weight compared to QD mounts

• Enhanced reliability with less chance of loosening under fire

• Simpler setup and maintenance

• Universal compatibility with standard thread patterns

For shooters who value repeatability, precision, and durability, a direct thread adapter is often the preferred mounting solution.

Understanding HUB Thread Compatibility

Modern suppressor design has largely standardized around the HUB thread pattern, which measures 1 3/8-24 (1.375-24). This industry-standard interface allows suppressor owners to swap mounting solutions without replacing the entire suppressor.

If your suppressor is HUB compatible, you can choose from a wide range of mounting options—including direct thread adapters—while maintaining a secure and concentric connection to your firearm.

Next Level Armament HUB Thread Adapter

The Next Level Armament (NLA) HUB Direct Thread Adapter was developed to provide a rock-solid mounting option for shooters running HUB-compatible suppressors. After designing our Oscar, Eminent, and Predator suppressor lines around the HUB standard, Next Level Armament engineered a direct thread solution that prioritizes precision, strength, and long-term durability.

Each adapter is precision machined in-house to aerospace tolerances from a solid block of 12L-14 steel, ensuring exceptional concentricity and alignment. To further enhance longevity and corrosion resistance, every adapter is finished with a QPQ Nitride coating, delivering a hard, wear-resistant surface built for hard use.

Universal Fit and Suppressor Compatibility

Because the NLS HUB Direct Thread Adapter is manufactured to exact HUB specifications, it works seamlessly with any suppressor threaded 1 3/8-24 (1.375-24). This universal compatibility gives shooters maximum flexibility while maintaining a stable, direct thread connection to the barrel.

By eliminating QD components, this mounting solution helps reduce the risk of:

• Suppressor loosening during firing

• Inconsistent alignment

• POI shifts between shooting sessions

For shooters who demand repeatable accuracy and confidence in their suppressor setup whether at the range or hunting or conducting an operation, this is a major advantage.

Available Barrel Thread Options

To accommodate the most common firearm barrel threads, Next Level Armament offers the NLS HUB Direct Thread Adapter in three configurations:

• NLS HUB DTA1 – 1/2-28 barrel threads

• NLS HUB DTA2 – 5/8-24 barrel threads

• NLS HUB DTA3 – 13.5×1 LH barrel threads (SIG pattern)

This range ensures compatibility with popular AR platforms, precision rifles, and European-threaded barrels.
