DPMS AR-15 Enhanced Oracle A3 Flat-Top Upper Assembly 5.56x45mm NATO 1 in 9" Twist 16" Stainless Steel Barrel with YHM

This DPMS Enhanced Oracle AR-15 Upper Receiver comes fully assembled and ready for installation on any standard small pin lower receiver. The Oracle is an excellent entry-level upper assembly that incorporates the versatility of a Forged A3 Flat-Top configuration in selecting a preferred sighting arrangement with a solid, fully functional foundation of quality components. The Enhanced Oracle improves upon the original concept with the addition of a rock solid Yankee Hill Machine Lightweight Specter Length Quad Rail Handguard. This Free Floating Handguard covers a low profile gas block at the carbine gas port position. At 9.675" it is slightly longer than Mid-Length, providing for increased room to add tactical accessories and allowing for the off-hand to be placed farther out toward the muzzle for better target-to-target transitions and added control during recoil. The Enhanced Oracle features a 16" Stainless Steel Barrel, a true 5.56x45mm NATO chamber for use with either commercial or higher pressure military surplus ammunition, and employs a versatile 1 in 9" Rifling Twist rate that is capable of stabilizing a wide selection of different bullets up to about 69 grains in weight. The upper comes complete and ready to fire with an ejection port door, forward assist, shell deflector, charging handle, complete bolt & carrier assembly, and highly effective DPMS Panther Flash Hider. All aluminum parts are hard coat anodized to mil-spec and steel parts are manganese phosphate finished (parkerized) matte black.
