Nightforce NX8
Nightforce, established in 1992, is committed to delivering high-performance optics and mounting systems tested in the toughest environments. With nearly three decades of experience, Nightforce ensures optical clarity, consistent tracking, and rugged durability for military operations, competitive shooters, and outdoor enthusiasts alike. The NX8 Scope Series, a progression of the acclaimed NXS series, features an impressive 8x magnification range in a compact design, utilizing ED glass for enhanced clarity. Built to endure extreme conditions, the NX8 scopes are resistant to heat, cold, dust, and water. The ZeroStop elevation adjustment allows for rapid returns to zero, while the 50mm objective optimizes light transmission. The MOAR-CF2 reticle provides intuitive subtensions for fast target acquisition, making the NX8 ideal for versatile shooting scenarios.
Sightmark Citadel
The Sightmark Citadel is built for precision, offering a first focal plane reticle that adjusts with magnification to maintain consistent subtensions for accurate ranging at any level. This feature is ideal for long-range shooting, making range estimation simple and reliable. One of the key advantages of the Citadel is its red illuminated reticle, which enhances target visibility in low light, ensuring you don’t miss your shot in challenging conditions. I found the exposed, low-profile locking turrets to be incredibly user-friendly, providing quick adjustments when needed while the locking mechanism ensures accuracy even under stress. The 30mm single-piece tube, made from aircraft-grade aluminum, gives the scope exceptional durability, withstanding recoil and ensuring precise alignment over time. Finally, the fully multi-coated optics provide superb image quality, maximizing light transmission and delivering bright, accurate visuals.
