While it's a fairly capable weapon, as it's traditionally been held in the hands of those who've killed tens of thousands of Americans, I'm not sure it deserves mention.
Besides, of the five separate ones I fired, four of them jammed something fierce, a problem I never hand with the M-16A2 I fired for qual years back. Only one fired true, and that one was owned by a gunsmith.
My take is that if it takes a gunsmith to render it true, why would anyone rely on it for any use whatsoever? (unless one is a gunsmith)
