The roots of the Browning BAR run deep - going back to John M. Browning's first design for the U.S. military during the First World War. The sporting BAR's contemporary design offers shooters and hunters a lightweight semi-automatic rifle with refinements not present in the most popular modern sporting rifles, including a gas-piston design. The BAR MK 3 DBM is a variation of the BAR design offering shooters a detachable box magazine with a magazine well instead of the standard hinged floor plate design. The DBM model also comes with QD swivel cups (QD sling swivels included), 1913 Picatinny rail scope bases, and an 18" hammer-forged barrel (an optimal length for a multipurpose rifle chambered in the venerable 308 Winchester cartridge)
