Where accuracy meets superior firepower, the Barrett M107A1 .50 BMG Sniper Rifle is the product of over three decades of innovation, testing, and mechanical evolution. Based on the tried-and-true Barrett M82 .50 BMG rifle and then enhanced for the most demanding customers on earth, the United States Armed Services; the M107 semi-automatic rifle is able to deliver its .50 BMG payload rapidly and accurately without fail. Every component of the M107A1 has been optimized to ensure that the rifle is able to meet the demands of the mission without unnecessarily weighing down its operator during combat. As it stands the M107A1 weighs in 4 pounds less than its predecessors but every bit as tough due to its unique combination of steel, aluminum, titanium, and polymers. Additionally the Barrett M107A1 is optimized for suppressed fire using Barrett .50 BMG suppressors.
