This is Daniel Defense's MK18 upper receiver group in 5.56, built around a 10.3-inch barrel and finished in black. A complete URG drops onto your existing lower and instantly changes the rifle's mission, which makes it one of the most cost-effective ways to add a short, maneuverable configuration to a collection you already own. Daniel Defense's cold hammer forged barrels and proprietary free-float rail are the reason the MK18 pattern has been so widely adopted by professional users. Slim in the hand, rigid enough to keep accessories zeroed, and finished to the standard that made the brand.
