Introducing the Nightforce NX8 2.5-20x50mm Riflescope C665—a powerhouse of precision engineered into a compact frame ideal for sharpshooters who refuse to compromise on quality. Built on the robust foundations of the legendary NXS series, the NX8 model C665 offers an expansive 8x zoom range without the bulk, allowing for seamless transitions between close-quarter and long-distance targeting. With a versatile magnification range of 2.5x to 20x and a generous 50mm objective lens, this first focal plane scope provides unmatched clarity and performance across a wide array of shooting applications.

Expertly crafted with the highest-grade materials, this Nightforce riflescope promises unparalleled durability and accuracy. The one-piece 30mm tube is precision machined from aircraft-grade aluminum, ensuring it’s hardy enough to withstand the toughest conditions. The advanced ZeroStop elevation adjustment empowers swift and confident returns to zero, while the integrated Power Throw Lever (PTL) allows for rapid magnification changes. Whether mounted on a steadfast bolt-action or a rapid-fire semi-auto precision rifle, the NX8 C665 delivers exceptional reliability and precision.

When it comes to optical integrity, Nightforce has pulled out all the stops. The riflescope features ED glass for a sharp, color-accurate image, and unlike other scopes, its multi-coated lenses are individually matched and aligned through optical indexing to enhance light transmission for the brightest and clearest sight pictures. The Digillum illuminated reticle, combined with low-dispersion glass, ensures targets are clear and easily identified in any light condition. The Nightforce NX8 2.5-20x50mm Riflescope C665 truly redefines the limits of high-performance optics, making it an essential companion for any serious shooter.

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
