Ok. I Have read a lot on these forums about the AR-15. I shot many a M-16 in my years in the military. I feel the AR-15s today are very good. Here is my reservation about buying one myself. I have big questions about the effectiveness of the .223 caliber round. I have heard good things and bad. Larger pattern AR rounds, like the .308 I have not heard any bad things. If I buy a AR-15, what would be the best all round Home defense or on the battlefield? .223, .308, 6.8, 6.5 grendel, .450, or .50 beowolf?
And just for more interesting opinions, what brand of AR-15? Thanks.
