Long Range Hunting Scopes | 4.5-18x Illuminated, 50mm Objective, 30mm Tube, MIL Adjustment, Side Focus BEM4.5-18X501 SFIR
The BEM4.5-18X50 SFIR Rifle Scopes are positioned as a versatile precision shooting optic solution for shooters who require higher magnification capability, accurate adjustment performance, and reliable optical clarity in demanding outdoor environments.
The 4.5-18X magnification range provides excellent flexibility for medium-to-long distance shooting:
4.5X low magnification offers practical target acquisition and a wider observation range for hunting and field shooting.
18X high magnification provides enhanced target identification and precision aiming for extended-distance applications.
Compared with traditional hunting scopes in the 3-9X or 4-12X category, the BEM4.5-18X50 provides additional magnification capability, making it suitable for shooters who need more detailed observation and improved shot placement accuracy.
The side focus parallax adjustment system from 10 yards to infinity allows shooters to optimize focus at different distances and reduce parallax error. Combined with a 50mm objective lens, illuminated special reticle, 1/10MIL adjustment system, push-pull self-locking mechanism, and high-transmission optical design, this scope delivers a balanced solution between hunting versatility and precision shooting performance.
OVERVIEW
Key Advantages and Features
Flexible 4.5-18X Magnification Range
- The 4.5-18X magnification range provides an ideal balance between field usability and precision capability.
