Features

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.

Local Law Compliance

Certain firearm parts and accessories, including AR-style upper receivers, are subject to complex and frequently changing federal, state, and local laws and regulations. While an upper receiver may be lawfully sold and shipped as a component, the legality of possessing, assembling, configuring, or using an upper receiver in certain states (e.g., California, Washington State) and localities depends on how it is assembled, combined with other components, and ultimately used. You are solely responsible for ensuring that any assembly, configuration, possession, or use complies with all federal, state, and local laws, including any so-called “assault weapon” bans and short-barreled rifle restrictions. We do not provide legal advice and are not responsible for unlawful configurations or uses.
