Description
Ambidextrous Control & RIS III SBR Integration The DD4 RIII S elevates short-barreled rifle performance by integrating a fully ambidextrous lower receiver into a compact tactical architecture. Operators can seamlessly operate the bolt catch, safety selector, and magazine release from either side of the platform without shifting their hand position from the grip. Shielded by a lightweight 10.5-inch RIS III M-LOK handguard finished in Flat Dark Earth, the platform provides abundant modular attachment real estate while significantly reducing overall weapon weight.

Under U.S. law, purchasers must be 21 years of age or older, and transfers require federal NFA paperwork, approval processes, and Class 3 dealer facilitation.
