New First Focal Plane Nightforce 3.5-15x50mm F1 Scope

Nightforce Optics has just released a new first focal plane (FFP) scope, the 3.5-15x50mm F1. This scope, developed with input from the U.S. Military, should be ideal for tactical applications. The scope is available with Zero-Stop windage and elevation knobs calibrated in 0.10 Mil-Radian increments. When combined with Mildot or MLR reticles in the first focal plane, the Milrad knobs permit easy and precise ranging and holdovers. (Turrets with 1/4-MOA clicks are also available.)

The big news is the first focal plane engineering — something new for Nightforce. The advantage of the first focal plane design (also called “front focal plane”) is that the reticle size remains constant relative to the target’s dimensions at ALL magnifications. With a first-focal-plane reticle, the ranging marks, such as mildots, stay in synch with the target image at any zoom level. This allows the shooter to range targets and judge hold-offs at any magnification. As Zak Smith explains: “In variable power scopes, a first focal plane (FFP) reticle configuration means that the angular measure of the reticle features stays constant. No matter what magnification [the scope] is set at, 1 MOA will be 1 MOA and 1 MIL will demarcate 1 MIL.”

This scope is made in the USA. It is in short supply right now but Mike at CSGunworks.com has two units in stock, priced at $2290.00 including MLR reticle, Milrad turrets, and Nightforce UltraLite Rings. Those two scopes will sell quickly but Mike should have more inventory before Christmas. Call Mike at (916) 670-1103 for availability (price subject to change).

Ken from Nightforce Optics has announced that supplies of the new 3.5-15×50 F1 will be very limited for the next 4 to 6 months because Nightforce is fulfilling U.S. Army contracts. Ken notes that: “this new model riflescope, in the Mil-Spec version, is currently in use by several U.S. Army Special Forces groups.” Ken provided these details about the new Nightforce F1:

Product Information for the NXS 3.5-15x50mm F1

Manufacturer’s Suggested Retail Price is $2,410.00
Standard Features Include:
1) ZeroStop
2) Illuminated reticle
3) Side parallax adjustment
4) Set of Nightforce Ultralite 30mm medium rings, (limited time only)

Reticle Options:
1) Two mil-radian reticles are currently available: The Mil-Dot and MLR
a. Thin-line subtended measurement equals .250 MOA
2) Proprietary MOA type reticles will be available in the future. (Within the next four to six months)

Adjustment Options:
1) .250 MOA elevation and windage adjustments, ZeroStop
2) 1.0 MOA elevation and 1/2 MOA windage adjustments, ZeroStop
3) .10 Mil-Radian elevation and windage adjustments, ZeroStop

Ken adds: “Considering the fact that we will only offer the Mil-Dot and MLR reticle options in the short term, we believe the Mil-Radian adjustment option will be the most popular of the models listed above for the short term.”

First Focal Plane vs. Second Focal Plane Optics
If first focal plane design is better for ranging, one might ask “why aren’t all scopes made this way?” Well, there are tradeoffs. When shooting at known distances, if you’re trying to aim with extreme precision on a tiny X-Ring, you don’t want the cross-hairs to appear thicker as you turn up the magnification. With first focal plane reticle configuration, the reticle increases in thickness, as viewed by the shooter, as magnification increases. This means that, at higher powers, the reticle lines and mildots/hashmarks may obscure very small targets at long range.
