Product Description The RUGGED SUPPRESSOR 3-Lug Mount (OA001) replaces the piston assembly in your Obsidian suppressor, letting you quickly attach an Obsidian 9 or Obsidian 45 to 3-lug compatible fixed-barrel firearms. Designed as an internal mount to help keep overall length as short as possible, it enables fast attach/detach convenience without the need to manage piston-based walk-off on fixed barrels. Note: This is the suppressor (can) mount only; your firearm must have integral 9mm 3 lugs or use a 9mm 3-lug adapter.
