If you plan on using a lens with your ArmorTech sight, you will need to purchase the lens retainer (sold separately from the lens) to keep the lens from falling out of the scope.
This product is the 1-3/4" diameter, and screws into the back of the scope housing easily for a flat fit to the housing.
If using a lens with the ArmorTech, you will also need to purchase the ArmorTech Lens Frame or Lens Frame Set (sold separately). Another option for the lens retainer is the Hooded Lens Retainer if you wish to bring some shade from the sun to your pins.
