There is little doubt about your question. You will not be able to get for example a model 512 EOTech and a Magnifier for $500.00. If you are going to be shooting at distance and for precision a Scope is the answer. But also remember the 5.56/223 round is by far not the best choice for shooting long distance. Yes they will shoot at 600 yards as they do at Camp Perry every year! But the main factor is the effect of the wind on the bullet. That comment comes from experience. I agree with one of the previous posts. Get a Rock River or similar scope mount for your AR that moves the scope forward allowing proper eye relieve! Otherwise you will have a problem with a good scope. Then look at a Nikon Scope. For the money they have good glass and are top quality for under your $500.00 budget.
The Constitution is not an instrument for the Government to restrain the people. It is an instrument for the people to restrain the Government!
Today, we need a nation of Minutemen, citizens who are not only prepared to take arms, but citizens who regard the preservation of freedom as the basic purpose of their daily life and who are willing to consciously work and sacrifice for that freedom."
