The BEM4-16X50 SFIR Rifle Scopes are positioned as a precision-oriented high-magnification optic solution for shooters who require enhanced target observation, reliable adjustment performance, and versatility across multiple shooting environments.
The 4-16X magnification range provides an excellent balance between field usability and precision capability:
4X low magnification offers a practical field of view for target searching, tracking, and hunting scenarios.
16X high magnification provides improved target identification and aiming precision for medium-to-long distance shooting.
Compared with standard hunting scopes such as 3-9X or 4-12X configurations, the BEM4-16X50 provides additional magnification capability while maintaining a practical and versatile design suitable for a wide range of rifle platforms.
The side focus parallax adjustment system from 10 yards to infinity allows shooters to fine-tune image focus and reduce parallax error at different distances. Combined with a 50mm objective lens, illuminated special reticle, push-pull self-locking adjustment system, broadband multi-coated optics, and 30mm tube construction, this scope delivers a balanced solution for precision hunting and shooting markets.
