The Leupold Mark 5HD 3.6-18x44mm riflescope with the front-focal-plane TMR reticle and M5C3 elevation system (part no. 173296) is built around fast-handling controls for competition shooters who need to change magnification and dial elevation without breaking position. Leupold pairs the TMR reticle with a tactile throw lever for quick power changes, and M5C3 ZeroLock delivers extended adjustment travel with a repeatable return to zero. The Twilight Max HD optical system preserves contrast across varied light, and a 35mm tube supports the elevation range serious matches demand. Among competition-focused gun scopes, this Mark 5HD build is tuned for stage speed as much as precision.
