The Company Behind ZCO
Established in 2018, Zero Compromise Optic (ZCO) quickly positioned itself as a leader in the premium optics industry. Operating out of Austria and the United States, the brand is driven by experts with extensive backgrounds in optical engineering and rifle scope manufacturing. Their philosophy is simple yet bold—produce rifle scopes without compromise. The ZC527 embodies this commitment by combining the best materials, innovative designs, and precise engineering.
 

Optical Performance

 Superior Magnification and Visual Clarity
The ZC527’s 5-27x magnification range ensures exceptional versatility, allowing shooters to engage targets from mid-range to extreme distances. Unlike some long-range scopes that lose image sharpness at maximum magnification, the ZC527 retains pinpoint clarity with zero perceptible chromatic aberration or distortion.
 
 
Unmatched Light Transmission
The 56mm objective lens maximizes light intake, significantly improving image brightness in low-light conditions such as dusk and dawn. With advanced multi-coated lenses, the scope enhances contrast and color fidelity, ensuring targets remain clearly defined against varied backgrounds.
 
Expansive Field of View
A significant advantage of the ZC527 is its exceptionally wide field of view (FOV)— 21 feet at 100 yards (7 meters at 100 meters) at 5x magnification. This broader FOV provides a tactical edge, enhancing target acquisition speed and situational awareness, particularly in dynamic shooting scenarios.
 
 
 
Optimal Eye Relief and Exit Pupil
With an eye relief of 3.54 inches (90mm), the scope offers a comfortable and forgiving shooting experience across all magnifications. The exit pupil varies from 10.5mm at 5x to 2.1mm at 27x, ensuring sufficient brightness under diverse lighting conditions.
 
Mechanical Design and Functionality
 
 Reinforced 36mm Main Tube
Built on a 36mm single-piece aircraft-grade aluminium main tube, the ZC527 provides superior strength and increased internal adjustment capabilities. This design contributes to an elevation adjustment range of 35 MIL (120 MOA) and a windage range of 21 MIL (72 MOA), making it ideal for extreme long-range shooting without requiring additional elevation compensation.
High-Precision Turrets
The ZC527’s turret system is a masterpiece of engineering, delivering accurate, repeatable adjustments with distinct tactile and audible feedback. Key features include:
  • Locking Mechanisms: Ensures adjustments remain secure, preventing accidental turret movement in the field.
  • Zero Stop: A fool proof mechanical zero stop allows instant return to the preset baseline elevation.
  • 10 MIL Per Revolution: The elevation turret offers precise tracking with clearly marked indicators for quick reference.
  • Lockable Windage Adjustments: The windage turret incorporates a locking feature to maintain adjustments despite movement or recoil.
Reticle Selection
The ZC527 is available with a diverse selection of first focal plane (FFP) reticles, catering to different shooting preferences and mission requirements:
  • MPCT1X: A clean, streamlined reticle designed for shooters who prefer a less cluttered sight picture while maintaining essential holdover points.
  • MPCT2X: A refined milling reticle that offers a balance between simplicity and precision, suitable for competition and tactical applications.
  • MPCT3X: An advanced reticle with enhanced reference points for rapid shot correction and long-range holdovers.
  • MOA: A traditional minute-of-angle reticle designed for shooters who prefer MOA-based adjustments over MIL.
  • Tremor3: A widely used Horus Vision reticle featuring wind dots and rapid holdover markings, favored in dynamic shooting scenarios.
  • Tremor5: A further refined version of the Tremor3, providing even more precise hold points and wind compensation markers.
All reticles are designed to scale proportionally with magnification, ensuring accurate ranging, holds, and shot corrections at any power setting. For detailed visuals and specifications, Zero Compromise Optic provides comprehensive PDFs outlining each reticle's design and application.
 
 
Durability and Environmental Resilience
 
Built to Withstand Harsh Conditions
The ZC527 is fully waterproof, fog-proof, and shockproof, thanks to its nitrogen-purged, fully sealed housing. The scope is engineered to operate flawlessly in extreme temperatures, high humidity, and challenging terrains.
Recoil Endurance
Designed to withstand heavy recoil forces, the ZC527 remains stable and retains zero even when mounted on magnum-calibre rifles such as .338 Lapua Magnum and .50 BMG.
 
 
Real-World Usability
 Competitive and Tactical Advantages
Professional marksmen, long-range competitors, and tactical shooters consistently praise the ZC527 for its ability to track accurately, provide unparalleled clarity, and maintain zero under adverse conditions. Its reticle designs enable fast target acquisition and precise shot execution, making it a top-tier choice for elite shooters.
 
Law Enforcement and Military Applications
The combination of rugged durability, high-quality glass, and ultra-reliable mechanics makes the ZC527 a valuable asset for military and law enforcement snipers, where precision and dependability are mission-critical.
