Description

The Daniel Defense 10.3″ MK18 Complete Upper is the same complete upper receiver assembly used on their MK18 short barreled rifle and MK18 pistol. Using top quality components from their entirely in-house produced cold hammer forged barrels, legendary RIS II handguards, better than MIL-SPEC M16 bolt carrier groups means that you’re getting one of the best uppers available for the AR-15.
