Zero Compromise Optic ZC420H 4–20×50 Hunting Rifle Scope | ZCO Scopes

The Evolution of Precision Hunting Optics — Lighter, Slimmer, Uncompromising

When serious hunters talk about the best hunting rifle scopes on the market, one name consistently rises to the top: Zero Compromise Optic. The new ZCO ZC420H 4–20×50 builds on the legendary ZC420 platform, delivering the same world-class optical performance that made ZCO scopes a benchmark in precision optics — now re-engineered into a lighter, slimmer, field-ready package.

Whether you’re glassing alpine ridgelines at first light or pushing hard on a fast-moving stalk, the ZC420H is built to perform where it counts.

Why the ZC420H Is One of the Best ZCO Scopes Ever Made

Zero Compromise scopes have always stood apart from the competition by refusing to cut corners. The ZC420H continues that tradition with a suite of features that puts it firmly among the top hunting riflescopes available today:

• Reduced weight of just 925g — every gram matters when you’re covering miles of mountain terrain
• Slimmer, streamlined profile for superior rifle handling and faster target acquisition
• Robust 36mm main tube retaining the mechanical strength ZCO scopes are renowned for
• 92% light transmission for exceptional clarity and detail in low-light conditions — dawn, dusk, and everything in between
• First Focal Plane (FFP) reticle for accurate ranging and holdovers at any magnification
• 4–20× magnification range — versatile enough for close-range driven hunts and long-range precision shots alike

Optical Clarity That Defines Premium Hunting Riflescopes

The ZC420H delivers the razor-sharp resolution and edge-to-edge clarity that hunters demand from a high-end rifle scope. With a 50mm objective lens, a maximum 10mm exit pupil, and industry-leading 92% light transmission, this scope gathers every available photon — giving you a brighter, crisper image when the light fails and the shot matters most.

A generous >90mm eye relief means comfortable shooting across a wide range of rifle platforms, reducing fatigue during long glassing sessions and ensuring a safe, repeatable cheek weld.

Precision Adjustments. Repeatable. Every Time.

ZCO scopes are trusted by professional hunters, military snipers, and precision rifle competitors worldwide for one reason: their adjustments work, and they work every time.

The ZC420H features:

• 0.1 MRAD click value for precise, tactile adjustments
• 26 MRAD elevation / 18 MRAD windage travel — ample range for extended long-range hunting
• Parallax adjustment from 25m to infinity for distortion-free targeting at any distance
• Repeatable zero that holds through hard recoil, temperature swings, and demanding field conditions

Built for the Field. Built to Last.

Hunters don’t operate in controlled environments. The ZC420H is engineered for the real world:

• Waterproof to 4 metres depth — fords, downpours, and misty mornings won’t stop it
• Functional from -25°C to +60°C — from frozen Nordic stalks to African plains hunts
• 328mm overall length — compact and balanced for a wide range of hunting rifles

Smart Illumination — Red & Green with AIM Technology

The ZC420H features a dual-colour illuminated reticle (red and green) paired with Zero Compromise’s proprietary AIM (Automatic Illumination Management) system. AIM intelligently manages battery life by switching off after 2 minutes of inactivity or based on positional directionality, with a full automatic shutdown after 2 hours — so you never need to worry about a flat battery in the field. Powered by a single CR2032 battery.
