I have a likely new Barrett M107A1S rifle chambered in 50 BMG with a 29” barrel. This rifle is new, but it is the original manual. Here are some features and stats from Barret

Utilizing state of the art design, manufacturing, and materials, every component of the rifle has been engineered to be lighter and stronger than its predecessors. In addition to a 4-pound weight reduction, the M107A1 is optimized for use with a sound suppressor, providing a much-needed signature reduction capability to the warfighter. Lighter, stronger, more accurate, and more capable; the M107A1 has truly been engineered for action.
