The Leupold Mark 5HD 3.6-18x44mm riflescope with the Tremor 3 reticle (part no. 173299), developed with Horus Vision, is built on a 6061-T6 aircraft-quality aluminum chassis for shooters who want match-grade reticle density without added weight. Leupold keeps the Tremor 3 grid on the first focal plane so holdovers and wind calls stay accurate at any magnification, and M5C3 ZeroLock elevation delivers tactile, audible clicks with secure return-to-zero. A generous eyebox speeds target acquisition, and the parallax adjusts precisely to 50 yards. Among aircraft-aluminum gun scopes with a full holdover grid, this Tremor 3 configuration favors durability alongside precision.
