NXS 3.5-15 x 50 F1
Created at the request of the U.S. military, who needed a scope that is extremely fast, applicable to a wide range of targets at various distances, and offering a choice of elevation/windage click values, reticles, ballistic turrets and Nightforce's patented ZeroStop technology. The reticle is located in the first focal plane, meaning its size remains in the same ratio to the target across the entire magnfication range. This has distinct advantages in high-stress situations, and when the user can expect to encounter targets from close-in to hundreds of yards away.

 

 

BallisticCaps

In addition to the standard turret cap marked with an MOA scale, two optional engraved ballistic turret caps are offered:

1) A-191 (.300 Win. Mag/190 gr. Sierra Match King), available with the 1.0 MOA elevation/.5 MOA windage version.

2) M118LR (.308/175 gr. Sierra Match King), marked in meters. The user can have a third party custom engrave the standard cap to match virtually any caliber, once that caliber’s ballistics are established.

      Three different windage/elevation adjustments are offered: .250 MOA, .1 Mil Radian, or 1.0 MOA elevation/.5 MOA windage. Two optional engraved ballistic caps are also available, one for the 1.0/.5 MOA marked for the A-191 (.300 Win Mag/190 gr. Sierra Match King), or for the M118LR (.308/175 gr. Sierra Match King) marked in meters. The standard cap comes with a .250 MOA scale, which the user can have custom engraved (by a third party) to match any caliber's ballistics.

      ZeroStop technology is standard, and a variety of reticles is offered. The F1 ships with a set of Nightforce's superb Ultralight titanium rings.

About first and second focal plane reticles.

Most American shooters are accustomed to reticles located in the second focal plane of a scope.

In this configuration, the viewed reticle size remains unchanged at all magnifications. For most applications this is preferred, and indeed most Nightforce scopes utilize the second focal plane location. For some applications, however, a first focal plane location is preferred. In this instance, the reticle appears to grow in size as magnification increases. 

In actuality, the reticle is remaining in the exact same proportion to the target at all magnifications.  This has advantages when using certain ballistic and rangefinding reticles, and under rapidly changing field conditions. The preferred reticle location for you depends upon how you use your scope and the conditions you will encounter.
