The Leupold Mark 4HD 2.5-10×42 riflescope with the PR1-MOA reticle (part no. 183741) gives MOA-trained competitors and precision shooters a compact 30mm optic with generous adjustment range. Leupold keeps the PR1-MOA reticle on the first focal plane, so subtensions and holdovers stay accurate at any magnification from 2.5x to 10x, and both elevation and windage carry a full 85 MOA of travel. Fine 1/4 MOA clicks and a sealed, weatherproof build round out a scope tuned for match use. Among MOA-based gun scopes for competition and precision shooting, this Mark 4HD is the compact match-ready option.
