Barrett M107

The XM107/M107 was originally intended to be a bolt-action sniper rifle, and in fact it was selected by the U.S. Army in a competition between such weapons. However, the decision was made that the US Army did not, in fact, require such a weapon. The rifle originally selected under the trials to be the XM107 was the Barrett M95.

It was also originally intended to be a static weapon for base protection or a weapon-system fitted to vehicles like the humvee - quite like the M2 browning machinegun is. It is mainly made for base protection, vehicle checkpoint protection and similar roles.

When the Army decided it no longer needed these weapons, it found that it had money already allotted for "XM107 rifles," and rather than deal with this complication, the decision was made to change the M82's designation to M107, and use the money to purchase those type of rifles instead. In summer 2005, the M82 finally emerged from its Army trial phase and was approved for "full materiel release", meaning it was officially adopted as the Long Range Sniper Rifle, Caliber .50, M107.

The Barrett M107 is a .50 caliber, shoulder fired, semi-automatic, sniper rifle. Like its predecessors the rifle is said to have 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 which moves back and forth with the barrel to assist in recoil reduction and helps reduce around 40% of the felt recoil. 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.

The Barrett M107, like previous members of the M82 line, are also referred to as the Barrett "Light Fifty". The designation has in many instances supplanted earlier ones, with the M107 being voted one of 2005's Top 10 Military Inventions by the U.S. Army.

The M107 cannot use rounds like the saboted light-armor penetrator (SLAP) but it can use the MK211 and is made for the anti-material role.

Barrett M107CQ

A commercial development of the "new" M107, the M107CQ is specifically designed where the firepower of a .50 caliber rifle is required, but the bulk of the M82/M107 series prevents the weapon from being used. The M107CQ is 9" shorter in overall length (all in the barrel) and 5 pounds lighter than the M107. According to the manufacturer the M107CQ is suitable for "use in helicopters, force protection watercraft, tactical scout land vehicles and as an urban soldiers combat multiplier for the close quarter battles of today."

In a close quarters role, snipers tend to attach an IR attachment onto the weapon-system for pointing out targets (especially at longer ranges) and also illuminating buildings.
