Ok. So gonna buy an AR soon. In the environment in which I live I think a 556 would be the most suitable caliber. Was considering an ar 10 but the ammo cost and weight and living in a populated area makes me think 556. Also I trained with it a lot in the military and I am comfortable with it and have other rifles in bigger calibers as well. Questions..... What is the best quality AR I can get? What price range am I looking at? What is the best ammo? Can I , and is it advisable, to seek ammo that is higher than 55 gr if I have a high quality rifle? If so where do I find it? Will I save significantly if I build my own AR? Just tryin to get a good general idea without havin to read through everything on the site. Price range is dependent on the size of my expected insurance check but it will be enough to buy something of quality. Thanks in advance for your help.
