The 1.375x24 HUB suppressor thread refers to a specific type of thread pattern used for attaching a suppressor to a firearm, with the measurements being:

• 1.375 inches in diameter (the outer diameter of the threaded portion)
• 24 threads per inch (the number of threads that fit into one inch of length)

Key Points about the 1.375x24 HUB Thread:

1. Thread Size and Compatibility:

   • The 1.375x24 thread is relatively large and is most often found on suppressors for rifles or larger-caliber firearms. The 24 threads per inch ensures a fine, secure thread fit.
   • Compatibility: To use this thread, both the suppressor and the muzzle device (like a muzzle brake or flash hider) need to have the same thread pattern. For instance, if the suppressor uses the 1.375x24 thread, you will need a muzzle device designed to match that thread size and pitch.
   • The 1.375x24 thread is commonly used in high-end suppressors that prioritize fast attachment and removal, along with a strong, reliable fit.
   • Modularity: The system allows for multiple suppressors to be used across different firearms as long as they have the corresponding 1.375x24 threaded muzzle device.
   • Stability and Safety: The threads ensure a solid and stable connection, preventing issues like suppressor looseness or misalignment during firing.
