Steiner was founded in 1947 by Karl Steiner post-war in Bayreuth, Germany. Steiner is now a name that has correlated with superiority in the optics industry for decades. Steiner manufactures premium quality binoculars with impressive glass like the Tactical 10x42 HD Binoculars or ShadowQuest 8x56 Binoculars favored by many. Steiner uses the same treatment on their scopes and sights,producing crystal clear images. The P4Xi 14x24mm P3TR Scope is a compact, tactical optic that is ideal for patrol rifles and AR platforms. The P3TR illuminated reticle is quick pointing and offers levels of illumination for day or night. For over 60 years, Steiner has perfected lightweight and durable optics made for the military, law enforcement, or outdoorsman.
