The Magpul MBUS Pro (Magpul Back-Up Sight) Front sight is an all-steel back-up sight with maximum functionality and strength with minimum size. The elevation is adjusted via a knob and does not require any tools. Easily mounts on a Picatinny rail including rail-height gas blocks. Positive detents keep the MBUS Pro at standard AR sight height when deployed or stowed. The sight is narrow enough to be compatible with most IR aiming lasers and lights. Finished with Melonite QPQ for extreme resistance to wear and corrosion.
