General & Mid-Range Hunting Scopes | 4-12x Illuminated, 50mm Objective, 30mm Tube, Side Focus, 1/4 MOA BEM4-12X501 SFIR
The BEM4-12X50 SFIR Rifle Scopes are positioned as a high-performance hunting and precision shooting optic solution for users who need increased magnification, enhanced target visibility, and dependable field performance.
The 4-12X magnification range provides a practical balance between observation speed and shooting precision:
4X low magnification provides a wider field of view for target searching, hunting movement, and closer shooting situations.
12X high magnification offers improved target identification and aiming precision for medium-to-long distance shooting.
Compared with traditional 3-9X hunting scopes, the BEM4-12X50 provides additional magnification capability while maintaining a practical and user-friendly configuration.
The side focus parallax adjustment system from 10 yards to infinity allows shooters to optimize image focus at different distances and reduce aiming error. Combined with a 50mm objective lens, illuminated special reticle, push-pull locking system, precise 1/4MOA adjustment, and durable weather-resistant construction, this scope delivers a reliable solution for demanding outdoor shooting applications.
