A2? A4? M4?
I'm about to invest in an AR rifle. I understand the 5.56 /.223 chamber differences, but while I'm looking, I'm coming across evidently several different models, A2, A4, and M4 mainly. Could somebody explain the differences in these models, and the advantages/disadvanges of each, or at least direct me to an article on this subject? Thank you.
