KDG front sight replacement rail was designed to provide extra real-estate in place of the OEM FN Scar front iron sight. This allows the user to replace the OEM iron sight with any aftermarket iron sight of their choice. This rail segment will also give added room for other accessories like pressure switches, and laser / light devices. Manufactured from 6061 aluminum and anodized for a hard coat finish.
Installation is simple. Remove the roll pin in the front sight stop (located on the right side of the front sight), slide the front sight off with all components. Slide the rail segment into place. Install set screw and tighten. Use caution & common sense to not over tighten the set screw.
Please Note: Due to manufacturing imperfections with the casting on the gas block, alignment cannot be 100% guaranteed from rifle to rifle.
Please Note: Due to the exchanging of hot gasses and transfer of heat, the gas block can get very hot. Be cautious with materials attached to this product.
