What is the HUB mounting standard for suppressors?

The HUB mounting standard, also known as Plan B, refers to a universal thread pitch of 1.375x24 inches (TPI). This standard allows for interchangeability between various suppressor brands and muzzle device adapters, offering significant flexibility.

Can I convert my old suppressor to the HUB mount?

Yes, it is possible to convert many legacy suppressors to the HUB (1.375x24) standard through professional gunsmithing. This process involves machining the suppressor core, integrating a new HUB adapter, welding, and precise thread chasing.

What are the benefits of converting to a HUB mount?

Converting to a HUB mount offers increased compatibility with a wide array of muzzle brakes and direct-thread adapters from different manufacturers. It can also lead to weight savings compared to older, proprietary mounting systems.

Who performs HUB suppressor conversions?

Specialized NFA gunsmiths and machine shops, such as Scott's Silencer Service featured in the video, perform these conversions. They possess the necessary precision machining equipment and expertise for NFA item modifications.
