M-16

Half of these definitons are not totally right. The M-16 was a piece of shit in 'Nam (like all say), but it is fucking accurate now. I have an AR-15 (Civilian Model of the M-16), and the .223 Rem can get in a 4x6 rectangle at 100 yards. But the SAR-1 (AK47 Replica) is better

No example comes to mind
