Take a look at the NZ Army's new Designated Marksman Rifle (7.62). I heard about this first through my friends at Soldier Systems.
I'm sure you guys will enjoy this video. A Lewis Machinery and Tool (LMT) rifle, with what looks like a Zeiss scope. Chambered for 7.62, this weapon is definitely capable of 1 Minute of Angle out to 800 meters with the right Optics and know how. Enjoy! Out Here-Brandon
