I have a dd5 in 6.5cm and I have it topped with a nightforce 4-16-42 with the tremor 3. I use the rifle for hunting (mostly predators), and target shooting to 1200 yards. I feel I could use a little more top end magnification, Other than that I love the optic. That being said looking for advice on compare able optic with more top end magnification. Must have locking turrets and a tremor 3 reticle.
