The Daniel Defense MK12 URG is a complete upper receiver group for the AR-15 chambered in 5.56mm with an 18-inch barrel. The MK12 is based on the special-purpose rifle concept, built for accuracy at extended distance, and Daniel Defense uses a cold hammer-forged barrel for consistency and durability. The upper arrives with a free-floated handguard and is ready to pair with a compatible lower for a precision-oriented rifle. It is a popular option for shooters who want a ready-made upper with the accuracy and finish quality Daniel Defense is known for.
