High-Zoom Large-Objective Rifle Scopes | 2-20×50 SFIR Rifle Scope with 34mm Tube, Red Illumination, Side Parallax and Push-Pull Locking Turrets BEM2-20X501 SFIR
The BEM2-20X50 SFIR Rifle Scope is positioned as a high-performance, wide-magnification hunting and precision shooting optic for hunting equipment brands, long-range optics distributors, sporting rifle suppliers, and OEM rifle scope manufacturers.
Featuring an extended 2-20X magnification range, this model combines lower-power field observation with the magnification needed for detailed target viewing at longer distances. The 2X setting supports broader target observation, while the 20X setting provides enhanced image enlargement for precision-oriented applications.
Compared with conventional 3-9X hunting scopes, the BEM2-20X50 offers a significantly wider zoom range, making it a versatile option for brands seeking to combine hunting flexibility with precision shooting features.
Its 50mm objective lens, 34mm one-piece tube, 0.1MIL adjustment system, side parallax adjustment, and push-pull self-locking turrets make it particularly suitable for premium hunting rifle scope collections, multi-distance shooting optics, and private label precision rifle scope programs.
OVERVIEW
Key Advantages and Features
Extended 2-20X Magnification Range
The 10X zoom ratio provides exceptional flexibility for a hunting-oriented rifle scope. Lower magnification supports broader field observation, while the 20X setting delivers additional target detail for long-range shooting and precision practice.
Large 50mm Objective Lens
The 50mm objective lens provides substantial light-gathering potential, supporting detailed observation across different outdoor environments. This configuration is well suited to hunting and precision shooting applications where target visibility is important.
Red Illuminated Special Reticle
The red illuminated reticle provides an additional aiming reference against varying target backgrounds. The reticle configuration also offers potential for customized hunting and precision shooting applications.
Precision 0.1MIL Adjustment System
The elevation and windage turrets feature 0.1MIL click increments, supporting controlled adjustments during zeroing and precision shooting. The specified ±20MIL adjustment range offers flexibility for different sighting requirements.
Push-Pull Self-Locking Turrets
The push-pull locking mechanism helps protect selected turret settings against unintended movement during handling, transportation, and outdoor use.
Side Parallax Adjustment
The side parallax system offers adjustment from 10 yards to infinity, helping shooters refine focus and minimize parallax error across different observation distances.
Durable 34mm One-Piece Tube
The 34mm one-piece tube provides a strong structural foundation for the optical and adjustment systems. Combined with shock resistance, nitrogen filling, and fogproof protection, it supports demanding outdoor shooting applications.
Broadband Multi-Coated Optics
The broadband green-coated optical system helps reduce surface reflections and supports image clarity during outdoor observation. The adjustable diopter provides additional viewing flexibility for individual users.
Application Scenarios
Open-Country and Mountain Hunting
The BEM2-20X50 is suitable for hunting environments where observation distances vary across open fields, mountain valleys, and expansive terrain.
The lower magnification settings provide a broader viewing perspective for locating game, while higher magnification allows hunters to examine distant subjects in greater detail.
The 50mm objective lens offers practical light-gathering potential for outdoor observation, while the illuminated reticle provides an additional aiming reference in changing lighting conditions.
Predator and Varmint Hunting
The extended 20X magnification makes this model particularly attractive for predator and varmint hunting in open environments.
Its variable magnification allows users to adjust their viewing power according to target distance, while the side parallax system supports focus refinement when observing smaller targets at different distances.
Long-Range Precision Target Shooting
The BEM2-20X50 provides useful flexibility for shooters who require detailed target observation and controlled aiming adjustments during long-range practice.
The 0.1MIL elevation and windage adjustment system supports precise corrections, while the push-pull locking turrets help reduce accidental changes to selected settings.
The 20X maximum magnification is especially useful for deliberate shooting from stable positions.
Multi-Distance Sporting Rifle Applications
The 10X zoom ratio allows the BEM2-20X50 to cover a broad range of recreational sporting applications.
Its combination of lower-power observation, higher-power target detail, and adjustable parallax makes it suitable for range training, accuracy testing, and general-purpose precision shooting.
