The Nightforce NXS 3.5-15x56 Zero Stop Riflescope (HV Reticle, .250 MOA Turrets) with larger 56mm objective lens augments the brightness of the scope. Designed to benefit law enforcement organizations but equally as effective at long-range hunting situations, this NightForce rifle scope performs extremely well in low light and twilight situations due to its larger objective lens size. A wide exit pupil diameter of 14.5mm at 3x certainly helps the NightForce NXS 3.5-15x56 .250 MOA Scope's low light capability and target acquisition is simple with the rifle scope's near 28 foot field of view (at 3x magnification).
The body and weight of this riflescope are only slightly larger than that of the NightForce NXS 3.5-15x50 Scope, but you get much better range and light transmission with the larger NXS 3.5-15x56. The NightForce NXS 3.5-15x56 ZeroStop RifleScope also features NightForce's unique high speed Zero Stop functionality. Once you've sighted in your rifle scope, ZeroStop lets you return to that sighted setting instantly, even in total darkness. You don't even have to count clicks using Zero Stop.
