The Configurable Field Spotting Scope (CFS) 6-36x50mm F1 was designed with practical field use in mind, with an emphasis on balanced ergonomics, flexible configurations, and refined optical quality, while maintaining the ruggedness Nightforce is known for.

This first focal plane spotting scope features reticles that are adapted from the most popular riflescope reticles. The field-ready nature of the CFS 6-36 is reflected in the streamlined, compact, and straight design, which allows for convenient, snag-free storage and transport in, or on, a pack. The rubber knurling, 120° travel, and central location of the user controls aid in quick adjustments, while minimizing unnecessary movement and maintaining stability.

Designed with configurability in mind, the Spotting Scope Accessory Cage and Spotting Scope Accessory Platform (s-RAP) provide reliable platforms for attaching thermals, night vision, red dots, laser rangefinders, data cards, and other devices, making the CFS 6-36 ideal for the professional user.

Leveraging the highly regarded MIL-XT™ reticle, the MIL-XTs™ has been optimized for spotting scope use.

As a variable power, first focal plane reticle, the MIL-XTs™ has features tailored for use at both low and high magnification settings. This provides the versatility required by today’s precision rifle shooters and spotters.

At low magnification, the 50 Mil-Radian “goal posts” to the left and right of center provide coarse Mil-Radian adjustments, facilitating clear shooter/spotter communication.

At high magnification, the inverted grid of the reticle is offset to maintain a clear view of bullet trace, while providing fine subtensions for precise corrections. Additionally, a section of 0.1 Mil-Radian subtensions is included at the base of the grid for accurate range estimation.
