Long Range Hunting Scopes | 10-50x Illuminated, 50mm Objective, 30mm Tube, Side Focus, 1/4 MOA Adjustment BEM10-50X50 SFIR
The BEM10-50X50 SFIR Rifle Scopes are positioned as a maximum magnification precision optic solution for professional shooters who require extreme target observation capability, fine aiming control, and reliable mechanical performance at extended distances.
The 10-50X magnification range is designed specifically for highly specialized shooting scenarios:
10X low magnification provides sufficient target observation capability for long-range shooting environments.
50X high magnification delivers exceptional image detail and precision aiming performance for extreme-distance targets.
Compared with traditional hunting and general-purpose rifle scopes, the BEM10-50X50 is designed for shooters who prioritize maximum magnification, target analysis, and precision correction rather than rapid close-range engagement.
The combination of a 50mm objective lens, illuminated special reticle, side focus parallax adjustment from 10 yards to infinity, 30mm one-piece tube, precision 1/4MOA adjustment system, push-pull self-locking mechanism, and broadband multi-coated optical system creates a professional optic platform for advanced precision shooting markets.
OVERVIEW
Key Advantages and Features
Extreme 10-50X Magnification Range
- The 10-50X magnification range provides one of the highest magnification levels available for precision shooting applications.
- The lower magnification allows initial target acquisition, while the 50X setting provides maximum detail recognition for extreme-distance shooting.
Precision 50mm Objective Lens
- The 50mm objective lens provides strong light collection capability and supports a bright, clear sight picture.
- This helps maintain optical performance during long-range shooting sessions under changing lighting conditions.
Side Focus Parallax Adjustment
- The side focus system allows shooters to adjust focus from close distances to infinity.
- This helps minimize parallax error and improves accuracy during precision shooting.
Illuminated Special Reticle
- The electronic illuminated reticle improves aiming visibility in different lighting environments.
- The customizable reticle platform allows adaptation for competition shooting, target shooting, and specialized markets.
Fine 1/4MOA Adjustment System
- The ±25MOA elevation and windage adjustment range with 1/4MOA click value provides precise correction capability.
- This allows shooters to make fine adjustments during zeroing and competitive shooting.
Push-Pull Self-Locking System
- The locking mechanism helps prevent accidental turret movement during transportation and field use.
- This improves reliability for professional shooters.
