The Leupold Mark 4HD 2.5-10×42 riflescope with the illuminated TMR reticle (part no. 183738) brings first-focal-plane precision to a compact 30mm package built for competition and precision field use. Leupold keeps the TMR reticle scaling accurately across the 2.5-10x zoom, and M5C3 elevation gives multi-revolution capability for long-range dialing in fine 0.1 MIL increments. A 42mm objective balances light gathering with a manageable scope profile. Among compact gun scopes for precision and competition stages, this Mark 4HD is built for shooters who don’t need maximum magnification to shoot maximum precision.

Frequently Asked Questions

Why choose 2.5-10x over a higher-magnification Mark 4HD? It suits competition stages and precision field work at closer to mid-range distances, where a lower minimum magnification and compact size are an advantage.

What does M5C3 elevation offer? Multi-revolution capability for long-range dialing, letting the turret cover more total distance than a single-revolution design.
