The FAB DEF Front Poly FLIP-UP Sight BLK is a versatile sight designed for use as a primary or back-up option. Its ergonomic angel-wing shaped front shroud helps center the image with any front sight. When folded, the sight has a low profile that is smooth and inconspicuous, preventing snagging on gear or brush. The instant spring-locked deployment mechanism ensures secure deployment, while wind age adjustments can be made easily and rapidly without tools, with positive detent locking.
