The Daniel Defense AR-15 DD4 RIII Upper Receiver Assembly is built around a 16 inch Cold Hammer Forged Government Profile barrel, a GRIP-N-RIP Charging Handle, and mid-length gas system, known to have a smoother recoil impulse, which adds to this upper's accuracy by allowing for quick but precise rapid fire. It features a 12.5 inch lightweight RIS III rail—modeled after the revolutionary RIS II two-piece handguard developed for SOCOM—features M-LOK attachment for lighter weight while still offering M203 grenade-launcher attachment. All Daniel Defense complete upper receiver groups come standard with an M16 profile bolt carrier group. Features Cold Hammer Forged barrel Pinned Low Profile Gas Block GRIP-N-RIP Charging Handle
