Guntec EZ Sights Features The GunTec USA EZ Sights are built from a Zytel polymer composite body paired with steel internals giving the sight set a lightweight feel without sacrificing the durability needed for reliable deployment. The dual rear aperture option allows a shooter to pick between a larger aperture for close range fast acquisition or a smaller one for more precise aiming at distance. A low profile design keeps the sights flush with the rail height when folded which keeps them from snagging gear or blocking an optic mounted on the same plane. Windage and elevation adjustment on both the front and rear sights lets shooters zero the set to their rifle. Installation is quick thanks to the sight set s design for any flattop receiver or Picatinny rail making it a straightforward upgrade for AR-15 owners. The push button lock on the steel internal flip down system prevents the sights from folding down unintentionally during use which matters when a shooter needs a reliable backup if a primary optic fails. Because the sights stay low profile until needed they add a dependable sighting system without crowding the top rail or interfering with other mounted accessories. This combination of lightweight construction and a rapid acquisition design makes the EZ Sights a practical backup option for AR-15 shooters.
