OVERVIEW
Key Advantages and Product Features
Ultra-Wide 4-24X Magnification Range
The 4-24X magnification range provides exceptional flexibility from hunting situations to advanced long-range shooting.
The low magnification setting supports field observation and target acquisition, while the 24X setting enables detailed target analysis and precision aiming at extended distances.
Large 50mm Objective Lens
The 50mm objective lens improves light collection capability and supports a brighter sight picture.
This makes the scope suitable for outdoor shooting environments where lighting conditions may vary throughout the day.
High Magnification Precision Capability
The 24X maximum magnification provides excellent target observation capability for long-distance shooting.
It is suitable for shooters who require enhanced detail recognition and accurate shot placement.
Mechanical Illuminated Reticle System
The mechanical illumination design provides reliable reticle visibility without relying on complex electronic systems.
The special reticle platform can be customized according to different hunting and precision shooting requirements.
MIL Precision Adjustment System
The ±15MIL elevation and windage adjustment range with 1/10MIL click value provides accurate correction capability.
This supports shooters who use ballistic calculations and precision shooting methods.
Side Focus Parallax Adjustment
The side focus system allows shooters to adjust focus from close distances to infinity.
This helps reduce parallax error and improves aiming consistency during long-range shooting.
Push-Pull Self-Locking System
The locking mechanism helps prevent accidental turret movement during transportation and field use.
This improves reliability for hunters and professional shooters.
Durable One-Piece Tube Construction
The 30mm one-piece tube design provides excellent structural stability.
Combined with shock resistance, nitrogen-filled fogproof protection, and waterproof construction, the scope is designed for demanding outdoor environments.
High Transmission Optical Performance
The broadband multi-coated optical system improves brightness and image clarity.
The high single-surface transmission performance helps provide a clearer sight picture in changing lighting conditions.
Application Scenarios:
Long-Range Hunting Applications
The BEM4-24X50 SFIR Rifle Scopes are designed for hunters who require extended magnification capability in open fields, mountains, and long-distance hunting environments.
The 4X low magnification allows practical target searching and tracking, while the 24X magnification provides detailed target identification and improved aiming precision for challenging long-range shots.
The illuminated reticle improves visibility during dawn, dusk, and changing outdoor lighting conditions.
Varmint and Predator Hunting
The wide 4-24X magnification range makes this optic especially suitable for varmint and predator hunting applications where shooters require both flexibility and high-detail target observation.
The high magnification capability allows better identification of smaller targets at longer distances, while the lower magnification maintains practical field usability.
Suitable applications include:
- Predator hunting
- Long-range varmint control
- Small target shooting
- Open-field pest management
Long-Range Precision Shooting
The BEM4-24X50 SFIR provides advanced magnification capability for precision shooting and range applications.
The MIL-based adjustment system allows shooters to make accurate elevation and windage corrections during zeroing, ballistic adjustment, and shooting practice.
The high-power 24X magnification provides enhanced target detail for shooters requiring precise aiming performance.
Advanced Sporting Rifle Applications
The durable one-piece tube construction and broad magnification range make this scope suitable for advanced sporting rifle platforms.
It provides a flexible optic solution for shooters who need one scope capable of handling hunting, range shooting, and long-distance precision applications.
