Nightforce ATACR 4-20×50 F1 Scope

 The Nightforce ATACR 4-20×50 F1 is perfect if you are looking for a mid power scope. It was designed to work equally as well on the top of a bolt action or a semi automatic rifle. The scope is small and lighter than the ATACR 5-25×56 F1, but offers a 25% magnification improvement over the ATACR 4-16×42 F1. Features Digillum, ZeroStop turret, power throw lever, ED lenses, and 20x max magnification.


Horus TREMOR3 Reticle – Illuminated

The TREMOR3 reticle is all about faster shooting.  The Accuracy 1st – Speed Shooting Formula is built right into the elevation hold of the reticle making even faster shooting possible.  It’s field proven to make wind calls easier.  The reticle also allows one to accurately mil targets very quickly. Illuminated version.

MOAR F1 Reticle

The Nightforce MOAR reticle is a major advancement in precision shooting. A floating center crosshair two MOA wide and two MOA tall provides a precise aiming point— especially on smaller targets at longer ranges. One MOA elevation and windage spacings provide for more accurate rangefinding and hold offs compared to ordinary reticles with coarser markings.

The MOAR F1 reticle features 1 MOA elevation and windage markings for accurate range finding and hold offs.  A floating center crosshair and bold 3, 6 and 9 o’clock posts make this reticle fast and easy to use in the field.  This MOAR F1 reticle features over 80 MOA of elevation below center and total windage of 40 MOA on most models.
