ATN Thor 4, Thermal Rifle Scope with Full HD Video rec

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.
