The Marksman 3x30 Prism Scope is as sharp as it looks. Featuring a hard annodized aluminum finish with 3x magnification. Ideal for rapid mid-range target acquisition out to 200 yards. This scope uses a glass prism optical system rather than a refracting lens system like traditional scopes, allowing for better optical quality in a much smaller package. The crystal clear optics give a comfortable eye relief of 3.5 inches. The reticle can illuminate in red or green with multiple brightness levels or viewed in black when off to cover most lighting environments
