High-Zoom Large-Objective Rifle Scopes | 3-30×56 SFIR Rifle Scope with 34mm Tube, Red Illumination, Side Parallax and Push-Pull Locking Turrets BEM3-30X56SFIR
The BEM3-30X56 SFIR Rifle Scope is positioned as a high-magnification, precision-oriented rifle scope for long-range shooting equipment brands, competitive shooting suppliers, hunting optics distributors, and OEM rifle scope manufacturers.
Featuring a 3-30X magnification range, this model combines practical lower-power observation with powerful magnification for detailed target viewing at extended distances. The 3X setting offers greater flexibility for locating targets, while 30X magnification supports detailed aiming in precision shooting applications.
Compared with conventional 4-16X or 5-25X rifle scopes, the BEM3-30X56 provides a broader magnification range, making it attractive for brands seeking a versatile optic that bridges precision hunting and specialized long-range target shooting.
Its 56mm objective lens, 34mm one-piece tube, 0.1MIL adjustment system, side parallax adjustment, and push-pull self-locking turrets create a strong product platform for long-range precision rifle scopes, high-power sporting optics, and private label rifle scope collections.
OVERVIEW
Key Advantages and Features
Wide 3-30X Magnification Range
The 10X zoom ratio provides exceptional versatility for a high-power rifle scope. Lower magnification supports target searching, while 30X magnification enables detailed observation for precision shooting and long-range target practice.
Large 56mm Objective Lens
The 56mm objective lens provides substantial light-gathering potential and supports detailed image observation. This configuration is especially relevant for shooters who require high magnification under suitable lighting conditions.
Precision 0.1MIL Adjustment System
The elevation and windage systems feature 0.1MIL click increments with a specified ±12MIL adjustment range, supporting controlled corrections during sighting-in and precision shooting.
Side Parallax Adjustment
Adjustable from 10 yards to infinity, the side parallax system allows shooters to refine focus and minimize parallax error across different target distances.
Push-Pull Self-Locking Turrets
The push-pull locking mechanism helps reduce unintended turret movement during transportation, handling, and outdoor shooting activities.
Red Illuminated Special Reticle
The red illuminated reticle provides an additional aiming reference for use against different backgrounds. The reticle platform also offers opportunities for application-specific OEM customization.
Durable 34mm One-Piece Tube
The 34mm one-piece tube provides structural support for the optical and adjustment systems. Combined with shock resistance, nitrogen filling, and fogproof protection, it supports demanding outdoor shooting applications.
Broadband Multi-Coated Optical System
The broadband green-coated lens system helps manage surface reflections and supports image clarity during outdoor observation and precision target shooting.
Application Scenarios
Long-Range Precision Shooting
The BEM3-30X56 is designed for shooters who require detailed target observation and precise aiming corrections at extended distances.
Its 30X maximum magnification helps users examine distant targets, while the 0.1MIL turret adjustment system supports controlled elevation and windage corrections.
The side parallax adjustment helps reduce parallax error when shooting at different distances.
Precision Target Shooting and Benchrest Applications
The high-power optical configuration makes this model suitable for supported shooting positions, recreational benchrest shooting, and accuracy testing.
Shooters can use lower magnification to locate targets and increase magnification for detailed observation during target practice.
The push-pull self-locking turret system helps protect selected adjustment settings against unintended movement during handling.
Long-Range Varmint and Predator Hunting
The BEM3-30X56 provides the magnification flexibility required for observing smaller targets across open terrain, agricultural fields, and grasslands.
The 3-30X zoom range allows hunters to select an appropriate magnification according to distance and environmental conditions, while the illuminated reticle offers an additional aiming reference against different backgrounds.
Open-Country and Mountain Hunting
For hunting environments involving wide landscapes and longer observation distances, the BEM3-30X56 offers a practical combination of lower-power field observation and high-magnification target detail.
The 56mm objective lens provides substantial light-gathering potential, while the nitrogen-filled, fogproof construction supports outdoor operation in changing temperatures.
