Mounted a 4x16X56 for my brother-in-law's Remington 700 in 7mm Rem. He is blind as a bat. Shot sub MOA and a very nice muley two months later. The scope turrets respond correctly and parallax adjust fine. Milldot reticle is clearly seen, but he has trouble with the focus. He really likes the scope and calls it the "Hubble Telescope".
