Details
The DD4™ RIII™ Upper Receiver Group is built around a 16 inch Cold Hammer Forged Government Profile barrel, a GRIP-N-RIP Charging Handle, and our 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. All Daniel Defense complete upper receiver groups come standard with an M16 profile bolt carrier group.
