Vector Optics Zalem 4-48x65 SFP Riflescope (SCOL-45) – Extreme Long-Range Precision with 12x Zoom
The Vector Optics Zalem 4-48x65 SFP Riflescope (SCOL-45) is engineered for shooters who demand ultimate precision at extreme distances. With its extraordinary 12x zoom factor, a massive 65 mm objective lens, and advanced ED (Extra-Low Dispersion) glass, this scope provides exceptional clarity even at maximum 48x magnification. Whether for long-range hunting, competitive shooting, or military-style applications, the Zalem delivers performance equal to the toughest demands.
Optical Excellence
At the heart of the Zalem is a 65 mm objective lens enhanced with ED glass to eliminate chromatic aberration and ensure a razor-sharp image at the highest zoom settings. The fully multi-coated lenses maximize light transmission, offering crystal-clear visuals from dawn to dusk. Edge-to-edge clarity ensures the entire sight picture remains distortion-free, making precise target identification possible even at extreme distances.
Versatile 12x Zoom Factor
With a zoom range from 4x to 48x, this riflescope adapts to a wide variety of shooting scenarios. At 4x magnification, it provides a wide field of view suitable for scanning terrain and initial target acquisition. At 48x, it allows pinpoint accuracy at ranges exceeding 1 kilometer, making it ideal for ultra-long-range enthusiasts and professional sharpshooters.
Advanced Reticle Design
The scope is equipped with the VET-L338 etched glass reticle, designed for long-range precision. This reticle provides detailed markings for range estimation, bullet drop compensation (BDC), and windage corrections, ensuring reliable accuracy in varied environmental conditions. Its intuitive layout allows shooters to make rapid yet precise adjustments without relying on external tools.
Precision Turret System
- Click Value: 1/8 MOA (approx. 3.6 mm at 100 m), allowing ultra-fine adjustment at long range.
- Total Adjustment Range: Over 55 MOA for elevation and windage, providing ample travel for high-angle shooting.
- Turret Features: Zero-reset and turret lock system to prevent accidental movement during critical moments.
- Side Parallax Adjustment: From 20 yards (18 m) to infinity, for sharp focus across all distances.
Build Quality & Durability
Crafted from a 35 mm aircraft-grade 6061-T6 aluminum monotube, the Zalem is built to endure the harshest conditions. It is shock-tested to withstand the recoil of .338 Lapua Magnum rifles and similar heavy calibers. The scope is also waterproof up to 1 m and fully nitrogen-purged, making it fogproof and suitable for use in extreme weather. Its matte-black anodized finish provides additional resistance against scratches and reflections.
Ergonomics & Shooter Comfort
- Eye Relief: 100 mm (4 inches), ensuring safety and comfort even with powerful recoil.
- Exit Pupil: 16.25 mm at 4x to 1.35 mm at 48x, providing a bright and adaptable viewing experience.
- Length: 405 mm, proportionate to its high-power performance.
- Weight: Approx. 1,050 g, substantial but balanced for precision rifles.
- Diopter Adjustment: Fast-focus eyepiece with –2 to +2 compensation for a sharp reticle view tailored to individual eyesight.
