This thing looks mean.
It’s the XM2010 sniper rifle, which — according to this USA Today article — has an effective range of nearly 40oo feet.
Not surprisingly, the USA Today article is otherwise pretty useless as far as meaningful information goes. (Caliber? What caliber?) Thanks to a link from The Firearm Blog, we have the details from PEO Soldier Live. (It’s chambered in .300 Winchester Magnum.)
Nice.
