The PTS ZEV Combat Sight Set comes with plain black rear sights and a bright fiber front sight. This combination gives a shooter a clear picture and easy pickup of the front sight to get shots on target faster and more confidently under all lighting conditions. Also, the wide rear square notch combined with the narrow front sight post increases sight alignment precision and sight picture confidence for accurate longer distance shots. The serrations on the sight bodies helps to reduce glare for a crisp sight picture and the aesthetic ZEV slashes on the rear sight body sides give the sights a distinctive flair. The sights may also fit WE and KJ G17s with some slight modification (please consult a professional airsoft technician for installation).
