Guntec USA Gen2 AR15 T6 Aluminum Rail Height Gas Block AR-15 750
Guntec's .750" set screw gas block allows for Same Plane height sights to be used on the front gas block. Railed AR15 gas block is available in Black or Cerakoted FDE. With this gas block you don't need a taller "gas block" height front sight and can mount a same plane more common front sight since the gas block rail is the same height as the flat top AR receiver.
