The DR-15 is the latest standard model from DPMS and features a classic mil-spec design to allow it to serve as a highly modular entry-level rifle. The M4 series closely emulates the world-famous service rifle of the US Military and features a flat-top design with the classic waffle-style stock and clamshell polymer handguards. A Magpul MBUS series rear sight is included. This model is chambered in 5.5x45mm NATO and features an all-black finish. One 30-round magazine is included.
