The Mission First Tactical Polymer Flip-Up Front Sight is a backup front sight that mounts on a 1913 Picatinny rail (Mission First Tactical part no. BUPSWF). Unlike other backup sights, it has a shroud that shelters the front post blade from debris and impact when the sight is folded. It uses standard iron sight elevation adjustment and accepts any standard front post blade. A slim profile lets the sight sit under most optics.
