dweste... the AR platform "black rifle" is the small block Chevy of the firearms industry...tremendous amount of stuff available to add on...you need a good trigger, and good sights (at my age optics)look up the shooting sports offering practical rifle or 3 gun in your area...check it out and ask questions...if you look at the videos I mentiioned you can wade through the "mall nija/gunstore commando" junk and see what world class shooters use... regards Les
