Magpul MBUS 3 Sight - front sight - black

The Magpul MBUS 3 Sight – Front is a lightweight, compact polymer back-up front sight for 1913 Picatinny rails. It is smaller than the original MBUS: just 0.47" tall when stowed and 1.38" wide, which mitigates snagging on the move.

The spring-loaded sight deploys with an ambidextrous button. Elevation is adjusted without tools using a wheel similar to the MBUS Pro. The front post offers two widths in one: a 0.06" Standard width for maximum visibility and a 0.04" Match width for precision. Standard AR sight height ensures broad compatibility. The front sight must be mounted on a railed forend on the same plane as the receiver rail; it cannot be mounted on a railed gas block due to heat and is not compatible with Magpul Hand Guards.
