Nightforce ATACR 4-20x50mm F1 Scope – 34mm Tube, Zero Stop MIL-C Reticle, Waterproof

Overview

The Nightforce ATACR 4-20x50mm First Focal Plane scope is built for demanding hunting environments where precision and durability matter. Its rugged aluminum housing sits on a robust 34mm tube, providing a steady platform for reliable mounting and consistent performance across long treks, variable light, and shifting weather. Expect crisp optics, a low-profile finish, and a sight picture you can trust when the moment counts.

Key advantages at a glance

• First Focal Plane design maintains true reticle proportions from 4x to 20x, aiding fast target acquisition.
• Zero Stop MIL-C reticle enables quick, repeatable dialing after dialing in holdovers or range-based adjustments.
• DigIllum PTL Mil-C reticle option provides a precise aiming reference for ranging and holdovers.
• 34mm tube offers solid mounting compatibility and consistent alignment across mounts.
• Durable aluminum construction balances lightweight feel with rugged field performance.
• Waterproof and fogproof seals protect internal optics from moisture, rain, dew, and abrupt temperature changes.

Design details that matter

With a First Focal Plane layout, the ATACR keeps reticle subtensions proportional as you zoom, simplifying holdover calculations in real-time. The zero stop feature helps you quickly return to your known zero, reducing adjust-to-shot time when distances or winds shift. The Mil-C reticle option aligns with MIL-based aiming references, supporting precise aiming across a range of shooting scenarios. The aluminum body is engineered to withstand the bumps and scrapes of field use, while the seal design protects against rain, fog, and humidity so the sight picture remains consistent when you need it most.

Field readiness and use cases

In the field, you may encounter first light, dawn glints, or overcast skies that wash out subtle contrasts. The ATACR is designed to retain edge-to-edge clarity across magnifications, helping you pick up movement, texture, and distant landmarks more reliably. The combination of a sturdy 34mm tube, a weather-sealed body, and a precise reticle system supports a range of hunting styles—from long-range varmint work to closer, fast-action engagements—without promising guaranteed outcomes.

What to expect in practice

• Clear, consistent optics that hold up under changing light conditions.
• Reliable zero retention and quick corrections when wind or distance changes.
• Balanced weight and durability suitable for all-day field tasks.
