The Daniel Defense DDM4 V7 Pro Upper Receiver Group (brand part number 23-128-20044-047) is a complete 18-inch upper built on Daniel Defense’s DDM4 V7 platform, giving a precision-minded AR-15 build extra reach and velocity over a standard 16-inch carbine. It ships with no sights, giving the buyer a clean slate to run their own optic. This is an upper receiver group only, with no lower receiver included, so it is not itself a regulated firearm.
