Check the listing for details. Parallax Throw Lever Vortex Strike Eagle 5-25 FFP. Condition: New. Listed at 10.00 USD. Throw lever for the parallax / focus adjustment on your Vortex Strike Eagle 5-25 FFP scope! Enhance your ability to adjust the scope quickly without changing your postion! New version - designed with input from DST Precision, the new version features two ears for easier manipulation and is slightly larger for easier installation and improved cold weather durability (designed and tested in cold Minnesota winters). Snug friction fit - no hardware required. Installation will require a soft faced punch and gently tapping the throw lever over the parallax dial. A 1-1/4" 12pt socket works great as well. It is recommended to install it with one ear inline with the 15 yard mark, which places the ears vertical when the parallax is set to 50 yards. I designed this just after the scope was released and have been testing it ever since - I wanted to make sure it met my standards before releasing it to the public.
