Long Range Hunting Scopes | 10-40x Illuminated, 50mm Objective, 30mm Tube, Side Focus, 1/4 MOA Adjustment BEM10-40X501 SFIR
The BEM10-40X50 SFIR Rifle Scopes are positioned as a high-power precision optic solution for shooters who require exceptional magnification capability, fine adjustment control, and reliable optical performance for extended-distance shooting.
The 10-40X magnification range is optimized for precision-focused applications:
10X low magnification provides practical target observation and initial target acquisition at long distances.
40X high magnification delivers enhanced target detail and precise aiming capability for demanding shooting scenarios.
Compared with general-purpose hunting scopes, the BEM10-40X50 is designed specifically for users who prioritize magnification, accuracy, and repeatable performance over fast-action shooting.
The combination of a 50mm objective lens, illuminated special reticle, side focus parallax adjustment from 10 yards to infinity, 30mm one-piece tube, 1/4MOA precision adjustment system, push-pull self-locking mechanism, and broadband multi-coated optical system provides a professional optic platform for long-range shooting markets.
OVERVIEW
Key Advantages and Features
Powerful 10-40X Magnification Range
