Fire Field 4x32 Tactical Rifle Scope FF13013 is a precision combat optic that is designed especially for military snipers, combining clear optics with durable construction and professional-grade hardware. These Fire-Field riflescopes are built around a set of fully multi-coated lenses that lend the scope excellent light transmission rates and clarity, giving you the vision you need to make those perfect, long-range shots. With a fixed magnification of 4x, the Firefield 4x32mm Mil-Dot Riflescope has a wide enough field of view to accurately track targets, but enough magnification that you can stay a safe distance away for your shots. Fire Field has enabled these riflescopes to mount easily to a wide assortment of weapons using the Weaver rail system and a pair of included Firefield rifle scope rings. You never have to worry about taking this rifle scope out in the rain; it is nitrogen sealed, making it internally fog proof and waterproof. Easy to use windage and elevation knobs make the scope simple to adjust, and the scope's wide eye relief makes it comfortable to use, even during extended stakeouts. For a tactical riflescope that gets the job done, choose the Fire-Field 4x Scope.
