Hello, I'm going to be completely honest. I don't know an AR from an AK. I live in suburban Delaware. If riots were to break out and all hell hits the fan like a lot of us believe it will, I am looking for some superior protection. At present I have a 40 Cal Beretta semi pistol and a Mossberg 9+ one tactical shotgun. I am looking to add a semi automatic rifle to my collection. Based on my situation, what would be your recommendation. I am aware that the 223 and 5.56 our standard with the AR. Should I move up in caliber? Or is this overkill for my situation. I would like to have 6 to 10 mags each holding 28 to 30 minimum. And remember, I would like a small scope possibly 1 x 30 if you think that is adequate. I look forward to your response. Geo.
