This is an EX-MOD optic - these units have seen real-world use in trials for the Sharpshooter II L129A2 platform. The L129A2 “Sharpshooter II” was rolled out across the British Army to various units, and this scope carries that operational pedigree into civilian hands.
The Nightforce ATACR 4–16x42 F1 (.1 Mil-Radian DigIllum PTL TReMor3) is a compact, high-performance precision riflescope engineered for demanding tactical and long-range shooting applications where mechanical reliability and advanced ballistic capability are critical.
Built around a first focal plane (FFP) optical system, the scope ensures that all reticle subtensions remain accurate across the full 4–16x magnification range, allowing the shooter to perform ranging, holdovers, and wind corrections at any power setting without recalibration. The optic utilises premium extra-low dispersion (ED) glass with fully multi-coated lenses, delivering high light transmission, excellent contrast, and minimal chromatic aberration. The 42 mm objective lens provides an effective balance between light-gathering performance and reduced overall size, maintaining usability in varied lighting conditions while preserving a streamlined profile suitable for modern rifle setups.
Central to this configuration is the Horus TReMor3 reticle, a highly sophisticated grid-based design optimized for rapid, hold-based shooting. It incorporates calibrated wind dots and a structured grid pattern that enables precise elevation and windage corrections without reliance on turret adjustments. This allows for fast target engagement and efficient follow-up shots, particularly in dynamic environments where speed and accuracy must coexist.
The elevation turret features Nightforce’s ZeroHold system, providing precise 0.1 milliradian click adjustments with highly repeatable tracking. The mechanism allows the shooter to quickly return to a preset zero while preventing accidental over-rotation below that point. The windage turret is capped to reduce the risk of unintentional adjustments in the field, reinforcing the scope’s operational reliability.
An integrated DigIllum digital illumination system enhances reticle visibility across a wide range of lighting conditions. Multiple brightness settings, including night-vision-compatible levels, allow the shooter to fine-tune illumination intensity without overpowering the sight picture or degrading target clarity.
Constructed from a single piece of high-strength aluminum with a 34 mm main tube, the ATACR is built to withstand severe recoil, environmental stress, and extended operational use. It is fully waterproof, fogproof, and shock-resistant, ensuring consistent performance in adverse conditions. Despite its rugged construction, the scope maintains a relatively compact form factor, making it suitable for rifles requiring additional rail space for accessories such as clip-on night vision or thermal devices.
Overall, this configuration of the ATACR 4–16x42 F1 is designed for users who require a durable, optically advanced, and mechanically precise riflescope capable of supporting both deliberate long-range engagements and fast-paced, real-world shooting scenarios.
