Average Rating
July 1, 2021

The DRS1X is a well built optic. FOV is bright and expansive. 2000+ hrs is exceptional performance. The AA batteries is a real plus, can obtained anywhere in the world. Indexed with the iron sights exactly. The reticle is fast and user friendly. Stands up well to AZ sunlight. Mounts very quickly and is secure. Request that Steiner develop an ARD for this optic. Job well done.
