i no the M on the name means model but wtf is the A mean like arrangement 2?

I'm not sure if that's the exact meaning but that's basically what it means. Arrangement/ Variant 2 You have the M-16 Then M16 A1, A2, A3, A4 Each has a different confuguration .

i'd always thought it was adaption. since A usually refers to a series of fixes/improvements.
