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.[2] 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.[2]
