Helpful Positive Review Pretty good so far by Trent, Verified Owner, May 12, 2024

Helpful Positive Review Seems to be a good value by Kirk Mayne, Verified Owner, June 17, 2024

Helpful Positive Review Greats scope for the money by Maximus, January 3, 2023
Have been running one of these on my precision .308 bolt action for about 3 years now. I can stack headshots on steel out at 700yd with it and see targets beyond that. I like that they are made in the phillipines and not china. There is a good amount...
