CASE KNIVES
High quality, extremely collectible handmade knives since the 1800s.
SHOP CASE KNIVESThe Leupold Mark 4HD 2.5-10x42 is a mid-power precision optic built for tactical carbines and hunting rifles where consistent holdovers and zero retention are non-negotiable. Most shooters face a frustrating tradeoff between lightweight hunting glass and heavy tactical scopes that offer reliable tracking. This Mark 4HD solves that dilemma by packing a professional M1C3 ZeroLock turret system and a First Focal Plane reticle into a compact 30mm chassis that won't weigh down your rifle.
The technical advantage here is all about mathematical consistency. In this magnification class, many scopes use a Second Focal Plane reticle, meaning your holdovers are only accurate at 10x. By placing the PR1-MOA grid in the First Focal Plane, the reticle stays proportional to your target at every zoom level. This ensures your ranging and elevation adjustments remain perfectly synced and repeatable from the bench to the field.
The 30mm aircraft-grade aluminum main tube keeps the total weight at just 21 ounces while maintaining rigid structural integrity under heavy recoil. Because the First Focal Plane PR1-MOA reticle scales naturally with the 2.5-10x magnification, your holdovers stay accurate during rapid transitions. Combined with the M1C3 ZeroLock turret, you get tactile multi-turn elevation adjustments with a locking mechanism that prevents accidental dialing while moving through the brush.
