Daniel Defense M4A1 Rail Interface System II (RIS II)

The Daniel Defense M4A1 Rail Interface System II (RIS II) is a versatile and innovative handguard designed for the M4A1 carbine. This product is part of the SOPMOD II program, which emphasizes the need for a free float M203 solution. The RIS II meets this requirement by integrating all necessary parts into the rail itself, allowing users to free float the M203 grenade launcher without additional parts or special tools.

Features

The Daniel Defense RIS II features aircraft-grade 6061-T6 aluminum, which ensures durability and a high level of accuracy. The free-floating barrel design enhances accuracy by preventing any contact between the barrel and the handguard. The two-piece design allows for the attachment of an M203 grenade launcher when the lower rail section is removed, making it a versatile system for various tactical applications.

The RIS II also features a battle-tested, six-bolt bolt-up system that securely attaches the handguard to the upper receiver. Grade 8 military specification fasteners ensure a robust and reliable attachment. The continuous upper rail platform and Mil-Spec 1913 Picatinny rails provide a stable and secure mounting surface for optics and accessories. Additionally, the handguard is coated with a Mil-Spec Type III hard anodized finish in FDE or black, providing a durable and corrosion-resistant surface.

Performance

Installation

The installation process involves attaching the handguard to the upper receiver using the patented bolt-up system. This may require some manipulation to get the alignment perfect, but once it is secured, the handguard remains stable and secure. A drill with an Allen attachment can speed up the installation process significantly.
