Upgrade every gun in your safe with a rugged Mark 4HD riflescope. Leupold took the legendary performance of their Mark 5HD and gave it a slimmer maintube that’s been packed full of professional-grade features. Whether you’re a dedicated enthusiast or a uniformed professional, the Mark 4HD’s optical clarity and lightweight design will get the job done at the range or in the field. The Mark 4HD series features four magnification ranges, giving you an accurate and reliable option for close-quarter engagements, long-range dominance, and everything in between. They’re available with a three-turn elevation dial for unmatched confidence at extreme distances, a precise ZeroLock windage adjustment that won’t budge when knocked around, and a side focus that’ll give you tack-sharp images down to 25 yards. And like all Leupold riflescopes, they’re waterproof, fog proof, and backed by their lifetime guarantee.
