I brought this up to a buddy who just came back from Iraq,Not countries my friend, they are all following the small caliber trend... these are individuals like US soldiers operating in Afghanistan and Iraq, some have been seen with m14's while others order custom made guns like the grendel counter sniper rifle which is upgraded to 6.5mm etc. They have complained as I said before about the poor killing effect of the 5.56mm in regards to long ranges
His MOS is 11 bravo (Combat infantry). He states that they are quite satisfied with the 5.56 round fired out of the M16 series rifles, most engagements take place at around 200 meters over in Iraq, U.S Army qualifies at a 300 meter range, the U.S Marines qualify at a range of 500 meters. If they are using M14s then they are M21 sniper set ups, some of these are still around with U.S Army and Marine reserve components. They are also using Bartlett 50 cal and Remington 700 BDL setups also.
