OVERVIEW
Key Advantages and Product Features
First Focal Plane Precision Reticle
The FFP reticle design maintains accurate scaling throughout the entire magnification range.
Shooters can use the reticle for ranging, holdover, and ballistic correction without recalculating values at different magnification settings.
Ultra-Wide 4.5-27X Magnification Range
The 4.5-27X magnification range provides exceptional flexibility for long-range applications.
The lower magnification supports target acquisition, while the maximum magnification allows detailed observation and precision aiming at extended distances.
Large 50mm Objective Lens
The 50mm objective lens improves light collection capability and supports a brighter, clearer image.
This configuration is suitable for demanding outdoor shooting environments where lighting conditions change throughout the day.
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 aiming consistency during precision shooting.
Mechanical Illuminated Reticle System
The mechanical illumination system provides reliable reticle visibility without depending on complex electronic controls.
The special reticle platform can be customized according to different 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 data and precision shooting methods.
Push-Pull Self-Locking System
The locking mechanism helps prevent accidental adjustment changes 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 during different lighting conditions.
Application Scenarios:
Long-Range Hunting Applications
The BEM4.5-27X50 FFP Rifle Scopes are designed for hunters who require precise target observation and aiming capability in open terrain, mountains, and extended-distance hunting environments.
The lower magnification provides enough field awareness for searching and tracking targets, while the high 27X magnification allows hunters to analyze target details and improve shot placement accuracy at longer distances.
The illuminated reticle enhances aiming visibility during early morning, evening, and changing lighting conditions.
Tactical-Style Sporting Rifle Applications
The combination of FFP reticle technology, high magnification range, and durable construction makes this optic suitable for tactical-style sporting rifles.
The scope provides advanced optical capability for users who require both observation range and precision aiming performance.
Precision Shooting Applications
The BEM4.5-27X50 FFP is designed for shooters who demand accurate ballistic references and repeatable adjustment performance.
The FFP reticle maintains consistent measurement capability across the entire zoom range, allowing shooters to apply holdovers and corrections more effectively.
The MIL adjustment system supports precise elevation and windage adjustments during zeroing and long-range shooting.
Suitable applications include:
- Precision rifle shooting
- Long-range target shooting
- Shooting competitions
- Ballistic testing
Varmint and Predator Hunting
The extended magnification range makes the BEM4.5-27X50 FFP suitable for varmint and predator hunting where shooters need detailed target identification at longer distances.
The 27X magnification provides additional capability for smaller targets, while the lower magnification maintains practical field usability.
Suitable applications include:
- Open-field pest management
- Predator hunting
- Long-range varmint control
- Small target shooting
