The M82A3 is a weapon featured in the singleplayer campaign of Battlefield 3. It has a 10-round magazine, semi-automatic fire mode, and extremely high firepower. It is only usable during the mission Kaffarov, where it is automatically equipped by Dimitri Mayakovsky after taking out a sniper in a fist-fight. Unlike the other weapons in the game, it has no name or pickup icon. The weapon comes equipped with an infrared scope.
Gameplay with the Barrett M82 in the single player mission Kaffarov in Battlefield 3.
Trivia[]
The M82A3's game files in Battlefield 3 contain all of the necessary files for customization in multiplayer — all of the attachments in-game are included in its file directories. It is possible the gun was not included due to the difficulty of balancing a .50 Caliber semi-automatic rifle to the rest of the Recon weapons.
If dropped for a different weapon in Kaffarov, the pickup message will stay as the weapon that was picked up (i.e. dropping the M82A3 for a PKP Pecheneg. After equipping the PKP, the message will still say " PRESS [ ] FOR PKP PECHENEG).
