The Barrett XM500 is a gas-operated, semi-automatic, anti materiel/sniper rifle in development by the Barrett Firearms Company as of 2010. It is fed by a 10-round detachable box magazine situated behind the trigger in bullpup configuration.
Based on the design of the Barrett M82/M107, it is intended to be a lighter, more compact alternative. Since the XM500 has a stationary barrel (instead of the recoiling-barrel design of the M82), it will likely have somewhat better accuracy. As with its predecessor, it comes with a removable, adjustable bipod mounted under the barrel, and a top-mounted Picatinny rail for attachment of a scope or other accessory.
