What Is the B&T Rotex HUB 1.375-24 Suppressor Adapter?

The adapter serves as the connection point between a HUB-compatible suppressor and a NATO-spec A2 flash hider. Instead of replacing an existing A2-compatible muzzle device with a proprietary mounting system, users with compatible equipment can utilize this adapter to integrate certain suppressors into their setup.

The 1.375×24 HUB thread specification has become a widely recognized mounting standard across many modern suppressor platforms, allowing manufacturers to develop interchangeable mounting solutions.

Key Features

Some notable characteristics include:

• Standard 1.375×24 HUB compatibility
• Designed for NATO-spec A2 flash hiders
• Stainless steel construction for durability
• Secure gate-lock and ratcheting attachment system
• Quick installation and removal on compatible equipment
• Compatible with both 5.56 NATO and 7.62 NATO platforms when used with appropriate suppressor systems.

HUB Compatibility Explained

The HUB mounting standard (1.375×24 TPI) has become one of the industry’s most common suppressor interfaces. Rather than locking users into one proprietary mount, HUB-compatible suppressors can often accept different mounting adapters depending on the desired muzzle device.

This flexibility makes HUB-equipped suppressors easier to configure across multiple compatible rifle platforms without changing the suppressor itself.

NATO/A2 Compatibility

One of the primary advantages of this adapter is its compatibility with NATO-spec A2 flash hiders.

Many service-style rifles already utilize A2-pattern flash hiders, allowing compatible suppressor owners to use existing muzzle devices instead of installing entirely new mounting systems. Proper compatibility depends on the flash hider meeting NATO/A2 specifications.

Construction and Design

B&T designed the adapter with durability in mind by using stainless steel components and a robust locking mechanism. The gate-lock and ratchet system helps provide repeatable attachment while reducing unwanted movement during use.

The adapter threads directly into HUB-compatible suppressors and may be secured according to the suppressor manufacturer’s installation recommendations.

Common Applications

This adapter is commonly selected for users who:

• Already own HUB-compatible suppressors
• Have rifles equipped with NATO-spec A2 flash hiders
• Prefer maintaining existing muzzle devices
• Need a repeatable suppressor mounting interface
• Want to take advantage of the versatility offered by HUB-thread suppressors

Things to Verify Before Installation

Before choosing any suppressor mounting adapter, it’s important to verify:

• Your suppressor uses the 1.375×24 HUB thread standard.
• Your firearm is equipped with a true NATO-spec A2 flash hider.
• The adapter is compatible with your specific suppressor model.
