175079 is a second focal plane scope and that's what I see on our listing.
The linear FOV at 100yds is 11.2 feet. The angular FOV at 100 yards is 2.1 feet.
Butler Creek really doesn't have any covers that are going to fit the VX-Freedom 4-12x40 eyepiece or objective lens housings very well. I would recommend the Leupold Alumina lens covers for a perfect fit.
