On top of being the standard firearm for the U.S. Army, Knight Armament's gas-operated sharp shooter is also the military's first semi-automatic weapon to be used as a sniper rifle in the field of combat. In comparison to the standard bolt-action rifle, the M110 Sniper Rifle has a 4-1 hit ration and an effective shooting range of up to 3,2000 feet. Sound suppressor night vision also provides a more clear and accurate targeting system, no matter the time of day. See for youself.
