Bushnell 4-Reticle Red Dot - 11 Brightness Levels, 4 Reticles, Free Rings Included - The changeable reticle makes this sight extremely versatile (Click Here to see pictures of the reticles). Turn the knob to use the 3 MOA dot for distance, the crosshair for quick acquisition and precision, the 10 MOA dot for close in and fast, and the dot within a circle for leading moving targets like flying waterfowl. These scopes are 1X non-magnified so there's no parallax error and it doesn't matter where the reticle appears in the scope. Fast, both eyes open target acquisition; Zero parallax error; Sights are visible in any light on any background; No front and rear and target to line up... put the dot on the target and fire! Unlimited eye relief for long guns, handguns, or Scout Scope applications. This sight features a 30mm tube and comes with free 30mm rings that mount to any standard Weaver style base.
