DPMS Sportical AR-15 5.56mm Upper Receiver Assembly

The DPMS Sportical AR-15 Upper Receiver Assembly comes fully assembled and ready to install on any standard small pin, mil-spec lower receiver. The Sportical is constructed of Extruded 7029 T6 Aircraft Grade Aluminum and is of the "Slickside" variety, with a sleek profile devoid of protrusions through the elimination of the conventional AR-15 forward assist, case deflector, and dust cover. The result is a clean, minimalist appearance that is both fully functional as well as lightweight. The Sportical provides an ideal foundation for later user customization, including all of the required attributes and components for solid, reliable performance, but without adding anything extraneous that would increase both the weight and price of the upper.

The Sportical features a 16" Light Contour "Pencil" Barrel for reduced weight, a true 5.56x45mm NATO chamber for use with either commercial or mil-spec ammunition, and employs the versatile 1 in 9" rifling twist rate capable of stabilizing a wide selection of different bullet weights. The upper comes equipped with heat resistant GlacierGuard polymer handguards, single rail gas block, charging handle, complete bolt & carrier assembly, and an A2 flash hider. Aluminum parts are hard coat anodized to mil-spec, steel parts are manganese phosphate treated (parkerized) matte black.
