These scopes were specifically designed for the Service Rifle match shooter who shoots at various distances up to 600 yards. This scope also makes a great optic for SWAT work as well as for a sporting rifle. Oversized tactical turrets allow for easy windage and elevation adjustments. The high-quality ED lenses provide enhanced image resolution. March Optics' MTR-5 reticle is offered non-illuminated or with a green-illuminated center dot. The larger center dot and green color make the illumination appear brighter for more contrast in daylight conditions.
