Product title: Hawke Sport Optics Riflescope - Vantage 4-16X50AO Mil Dot IR
Product description: Designed for long-range shooting, especially in low-light conditions, the Hawke Sports Optics 4-16x50 Vantage AO IR Riflescope boasts a large objective to draw in generous amounts of light to allow its use at dawn and dusk, or in heavily canopied areas. To further improve the scope's performance, all of its optical surfaces are fully multi-coated to boost light transmission and improve color fidelity, contrast, and overall image brightness. A large objective also helps to produce a comfortable exit pupil so that when the eye dilates in low-light the entire field of view is easy to see without having to move your eye or head to see the whole scene.
Product feature: Mil Dot IR Illuminated Reticle, 5 Brightness Levels in Red or Green, 1" One-Piece Maintube, 1/4 MOA / Click Impact Point Correction, 11-Layer Fully Multi-Coated Optics
