The ERATAC® backup-sight has been developed to offer a rugged and robust sight to withstand roughest conditions while offering at the same time the precision of a competition shooting sight. The combination of steel parts where absolutely essential and high grade aluminum parts wherever sufficient, gave us the possibility to implement a sight with minimalistic design, low weight and minimum height. Thanks to a special surface treatment all parts are corrosion resistant to withstand even maritime conditions. The spring-loaded folding mechanism reliantly protects the sight from damage when used under rough condition in the field. A backup-sight must enable the shooter to aim the gun quickly and intuitively especially when acting under stress. Eratac, therefore, designed the ERATAC® backup-sight in a way that the small and large ghost ring is same plane. It is not necessary to change the point of aim when the distance to the target remains unaltered. The height of this sight corresponds to the height of an AR15 standard sight and can be easily combined with products from other manufacturers. The front sight is available in two different versions. Eratac recommend to use the wide post (1.8 mm / 0.07”) for military purposes. When using the sight for competition shooting the smaller version with a 1.35 mm / 0.05” wide sight insert is recommended. No tool is necessary to alter the height of the front sight. The ERATAC® backup-sight is suitable for all AR15 front sights having an 8-36 UNF thread. Because of this, a large variety of after market front sights may be used. The ERATAC® backup-sight with its very low height of only 9 mm / 0.35” also facilitates the use of extremely low mounted optics. Heckler and Koch Style: Back-up sight, kit includes front-sight with 1.8 mm / 0.07“ wide post and rear-sight.
