Just bought my first AR-15 on sat. M&P AR-15OR. Now let the modding begin!!! For you experienced guys, this is what I'm looking for... I want a optic that I can do some plinking and range time. Probably out to 250-300 yards. I way also use for some home defense. Not wanting to go over $500. I like the Eotech's but I would assume I would need a magnifier for the longer range time? Primary arms has a Eotech XPS2 with their magnifier for a good price. Are their magnifiers any good? I know some also like the Aimpoints. Whats the advantages of one over the other? Is there anything else I should be looking at? I don't want a rifle scope, not the look I want and this a gun I don't see myself doing a lot of hunting with. Thanks for any help, Brent.
