Product Description: The Nightforce NX8 2.5-20x50mm F1 MIL Riflescope C631 is a top-of-the-line optical solution for avid rifle enthusiasts. This compact yet powerful scope builds on the unparalleled reputation of the NXS family. Offering an extensive 8x zoom range allows quick target acquisition at close proximity, in addition to precise, long-range shot placement. The sophisticated first focal plane design keeps the reticle size consistent with zoom level, bolstering shot accuracy across the scope's magnification spectrum.

Crafted with the legendary strength associated with Nightforce products, the NX8 Riflescope promises bomb-proof durability. Its robust one-piece 30mm tube is hewn from 6061-T6 aircraft-grade aluminum, ensuring integrity through the harshest conditions. Swift elevation adjustments are made effortless thanks to the patented ZeroStop technology, which allows for a speedy return to zero. An adjustable parallax setting starting at just 11 yards and the inclusion of the Power Throw Lever (PTL) enhance the overall versatility and ease-of-use. This riflescope is a game-changer in any shooting discipline, whether on the range or in the field.

Nightforce doesn't compromise on optical finesse; the NX8 2.5-20x50mm incorporates multi-coated ED glass for crystal-clear visuals, vibrant colors, and optimal light transmission. The TReMoR3 reticle, positioned in the first focal plane, and the Digillum reticle illumination extend your shooting capabilities to varying light conditions. Every component within this riflescope is meticulously polished and aligned, making the NX8 2.5-20x50mm F1 MIL the epitome of precision engineering and functionality.

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.
