Machined aluminum replacement for factory front sight gives your Sig the familiar AR-15/M16 sight picture and lets you use readily-available AR-type clamp-on Picatinny rear sights. Serves as a reliable backup sight that deploys and retracts with the press of the large, easy-to-find release button. Spring mechanism locks in both deployed and folded positions, and is concealed to resist fouling from dust and dirt. AR-style post is the correct height to regulate with Samson and other many other commercial Picatinny rail-mountable rear sights for the AR-15/M16 (will not work with SIG 556/522 factory rear sights). HK model has globe-style ears to give you a centered target-style shooting picture.
