Description and Features

The Steiner GS3 “game sensing” scope utilizes exclusive CAT (color adjusted transmission) lens coatings to amplify contrast in the peak human vision sensitivity range. The optimized contrast effectively separates game from leafy or shadow-dappled backgrounds, exposing your target to a clean, accurate shot. And the GS3 5x zoom range lets hunters from eastern whitetail country to western big game ranges pair their new scope with their favorite centerfire, rimfire or muzzleloader rifle. And or course, Steiner’s bedrock reliability will always deliver unfailing performance, whatever firearm or target you prefer.
