Re: Sight/scope for ar-15
I say decide whether you want to be able to have fast, quick shots while having a wide open view of your peripherals,
a scope to zoom in close so you can see your shots and be much, MUCH more precise and accurate.
Red dot style sights are generally not magnified, but there are 1.5x 2x, 3x and 4x sights. For scopes, 3-9x is common. 4-12x, 6-18x, and even higher for extreme long range.
