I have asked a few people this question and have met with zero good answers. Why couldnt the M16A1 have been updated to the M16A2 yet have full automatic capability? The gear you use to carry magazines would be compatible, the weapon would be lighter, and more parts would interchange. Why? Higher cyclic? More reliable? If the Cyclic is the answer, wouldnt that defeat the purpose of the 3 rd burst on an M16A2? To conserve ammo more effeciently? This has crossed through my head numerous times and figured I'd see if anyone else could help on this
I understand the military is looking at new weapon systems like the XM8 and all, but back when the SAW first came out....why not just upgrade?
