Five markers, locked separately, over a scale that still reads in 0.25 MOA underneath them. The Thrive X 4-16x50mm pairs that turret with a glass-etched PHR 3, built down from the PHR 2 structure to the references you actually reach for. A 50mm objective at the front, a 30mm 6061-T6 aluminum maintube through the middle, IPX7 sealing around all of it. The PHR 3 references are exact at 16x, and the turrets run capped or uncapped at 0.25 MOA per click. A scope set up once, properly, is not the part of the rifle you have to think about afterward. The 4-16x50 is built for that, and it is worth more at distance than anywhere else.
