This 3 Lug Mount replaces the piston assembly in your Obsidian9/45 allowing you to attach the Obsidian9 or Obsidian45 to 3 lug compatible firearms. This mount is designed to be internal so that your overall firearm length is as short as possible. Using a 3 Lug Mount allows you to quickly attach/detach your suppressor to fixed barrel firearms without having to worry about suppressor walk-off.
Note: This is the suppressor mount only. To attach your firearm must have an integral 9mm 3 lug or a 9mm 3 Lug Adapter.
