Quick Summary
The APLUSGEAR Metal Front and Rear 45 Degree Tilt Angle Sight BUIS Replacement Fibre Optic Iron Sight Set is a low profile iron sight set for Picatinny rails, designed to sit at a 45 degree orientation without interfering with a primary optic. It includes visible front red fibre sights and rear green fibre sights, with a dual aperture rear sight for CQB and precision aiming.
Who It Is Best For
This sight set is suited to buyers who want an offset backup sight option alongside a primary optic, and who value a compact layout that keeps the sights out of the way until needed. It is also relevant for anyone looking for ambidextrous sights with simple adjustment and a fibre optic aiming point.

The sights are described as machined from lightweight and durable aircraft aluminium and are made to mount securely to Picatinny rails. The rear sight uses dual apertures for CQB and precision use, and the knobs allow windage and elevation adjustment.
Pros: Low profile 45 degree design, fibre optic aiming points, and dual aperture rear sight for different aiming needs.
