Barrett .50cal



The Barrett M107 is a semiautomatic anti-materiel sniper rifle chambered in .50 BMG. Like its predecessors, the rifle has manageable recoil for a weapon of its size owing to the barrel assembly that itself absorbs force, moving inward toward the receiver against large springs with every shot. Additionally the weapon's weight and large muzzle brake also assist in recoil reduction. Various changes were made to the original M82A1 to create the M107, with new features such as a lengthened accessory rail, rear grip and monopod socket. Barrett has recently been tasked with developing a lightweight version of the M107 under the "Anti-Materiel Sniper Rifle Congressional Program," and has already come up with a scheme to build important component parts such as the receiver frame and muzzle brake out of lighter weight materials

Due to its heavy weight and high recoil, the weapon requires its user to be in a stationary prone position with some form of support. Because of this, its use in close quarters urban situations is limited. Despite this, the size of the round not only makes for an effective weapon against light armor or cover, but it is also an extremely long-range weapon. Successful engagements at over a mile and a half are not unheard of.

In-Game
The Barrett M82 model is used in the mission One Shot, One Kill, and is unlockable in multiplayer at level 49. Like all sniper rifles, it can be outfitted with an Advanced Combat Optical Gunsight (ACOG) scope. The M107 cannot accept a suppressor or a recoil reducer in-game. It is the most powerful sniper rifle in Call of Duty 4, and favored by many players for its sheer power and ability to make quick work of any enemies. However the sound made upon firing is distinctive and in multiplayer will give away the user's position.
