The Leupold Mark 3HD 4-12x40mm (180668), refined with high-definition optics and a robust feature set, stands as an exceptional choice for shooters and hunters alike who demand both precision and durability. This versatile rifle scope provides a generous 4x to 12x magnification range, allowing users to confidently engage targets at close to mid-ranges. Its 40mm objective lens ensures bright and clear views, while the FireDot TMR Illuminated Reticle offers sharp reticle visibility against dark backgrounds or in low-light conditions.

Built to Leupold's rigorous standards, the Mark 3HD features an Elite Optical System designed for optimal light transmission, glare reduction, and superior resolution, so you never miss a detail. The scope’s Custom Dial System (CDS) permits quick, on-the-fly adjustments to compensate for bullet drop and environmental conditions. Furthermore, offering a resilient 30mm maintube, the Mark 3HD is engineered to withstand the toughest field conditions, being entirely waterproof, fog-proof, and shockproof.

The ZeroStop system ensures a rapid and precise return to zero, enabling faster follow-up shots and keeping you on target. The Twilight Max Light Management system elongates your hunting window in the early mornings and late evenings when game is most active. Whether you're on the hunt or at the range, the Leupold Mark 3HD 4-12x40mm (180668) is a reliable companion that promises unparalleled performance and accuracy.

Price Match

We guarantee that we offer the best prices online.

If you come across another online retailer that sells the same item from the above manufacturer at a lower price plus shipping cost within one month of purchase, please let us know, and we'll refund the original payment for the difference in price.

For the guarantee to apply, the total order price of the item which includes shipping cost must be lower than what you paid us. For example, let's say you paid a total of $150 for an item on our site. If you see the same item advertised for $140 on another site but shipping cost is an additional $15, the guarantee DOES NOT apply since the total order price is $155.

On the other hand, if the same item is $140 but the shipping cost is an additional $5, the guarantee DOES apply since the total order price is $145 which is lower than what you paid us. The refund amount would be $5 for the difference. Please note we don't factor sales tax into the total order price when considering the guarantee. 

You can email us a link to the product on our website, as well as the link to that same product on our competitor's site within one month from your order date, to request for the partial refund. 

There are a few limitations on our price guarantee:

  • Items must be purchased from our site before requesting the Price Match guarantee
  • Promotions such as rebates and buy one, get one free offers are not eligible
  • The item must be in stock on the competitors website
  • The competitor must only be an online store and not have a physical retail location
  • The lower price cannot be found on an auction or market site like eBay, Amazon, Overstock, Wayfair, Jet, etc.
  • The competitor must be an Authorized Dealer or Retailer of that product
  • The Guarantee includes the total price of the item, but does not include sales tax
