Then I'd say jump on it....I promise one of those guys stationed in Afganistan would NEVER put a toy sight on a rifle that may decide him coming home or not.

As for the kit AR's...as long as the parts are Mil-Spec parts they are fine. I built my ShARps lower with the components I wanted and it runs flawlessly, slapped a bushmaster flat top upper with the Eotech and flip up rear iron sights (BUIS). Its a fine rifle...I'd feel like any fire fight is unfair to my advantage with that rifle in my hand. A few coyotes will agree that the eotech isn't JUST for close fire as well
