Where a figure is not published it is left out rather than estimated, which is why some sheets are shorter than others.

What this optic suits
Best for: a rifle where a failed scope is not an option.
Category: long range and precision riflescopes. The honest test for any optic is whether its numbers match your rifle and the distances you actually shoot rather than whether it is a good product in the abstract. Work out what ring height you need, what exit pupil the magnification gives you and how much elevation the distance demands, using the calculators on this site, then check this model against those answers.

A dash means the manufacturer does not publish that figure. We leave it blank rather than estimating it.
How we chose
We did not test these optics in person and we never claim to. Picks are researched from manufacturer specification sheets, published optical and ballistic formulas, and the recurring themes in verified owner reviews. Every pick is matched to a real objective diameter, a real tube size, a real ring height or a real exit pupil rather than to a price bracket, and it is placed in the tier where its capability actually belongs. Where a figure is shooter convention rather than a sourced number we label it, and where a manufacturer does not publish a figure we leave it out instead of estimating it.

Frequently asked questions
How much does the Leupold Mark 4HD 4.5-18x52 cost?
It was listed at $1,499.99 when this page was last compiled. Optics pricing moves frequently and promotional pricing is common, so treat that as a planning figure and confirm the current price before committing to a purchase or budgeting a whole setup around it.
Is the Leupold Mark 4HD 4.5-18x52 right for my rifle?
A rifle where a failed scope is not an option. Beyond that, the honest test is whether it physically fits and whether its numbers match the distances you shoot. Check the ring height its objective needs and the exit pupil its magnification gives before deciding.
Where do these specifications come from?
The manufacturer published figures, taken from the product listing and data sheet. We do not test products in person and we never claim to, so nothing here is a measured result. Where a specification is not published by the manufacturer it is omitted rather than estimated, which is why some sheets are shorter than others.
Will this fit my rifle and my rings?
Check three things in this order. The tube diameter has to match the rings exactly, because a 30 mm ring will not hold a 34 mm tube. The objective bell has to clear the barrel at the ring height you own. And the rail or base pattern on the receiver has to match the mount. Those three account for most returns in this category.
Is it worth buying this rather than the cheaper alternative?
Only if the thing it does better is something you actually need. The alternatives listed above each trade something specific, and on a first setup the money almost always does more good spent on a solid mount, a torque driver and a level than on upgrading the glass by one model.
Researched, not professional advice. This page is compiled from published manufacturer specifications, published optical and ballistic formulas, and owner-review consensus, not hands-on testing. Figures described as a rule of thumb are shooter convention rather than sourced numbers, and they are labelled that way wherever they appear. Ballistic figures come from a point mass model using the ballistic coefficient the maker publishes, so treat them as a starting point and confirm them on paper at a measured distance. Confirm your firearm is unloaded with the action open before you mount, level, torque or bore sight anything. Verify a zero only on a supervised range or a safe, legal backstop, know what lies beyond your target, and follow the law where you hunt and shoot, including rules on land access and permitted cartridges.
