Daniel Defense Rail Interface System II (RIS II) M4A1 Assembly
The Daniel Defense RIS II is a testament to precision engineering and innovation, crafted specifically for the demanding requirements of the United States Special Operations Command (SOCOM). Developed under the SOPMOD II program, this rail system addresses a critical need: providing operators with the capability to free float an M203 grenade launcher without resorting to additional parts or special tools.
What sets the RIS II apart is its integration. By incorporating all necessary components directly into the rail itself, Daniel Defense offers a streamlined solution that simplifies field operations. This design not only enhances weapon accuracy by eliminating barrel pressure but also maintains modularity for various mission needs.
Designed for use with the MK12 Low Profile Gas Block, this assembly ensures compatibility and reliability in high-stakes scenarios. Its robust construction and intuitive installation process make it an invaluable asset to any operator seeking both performance and efficiency on their platform.
The black finish of model 01-004-08001-006 adds a sleek aesthetic while maintaining low visibility—a crucial feature in tactical environments. With Daniel Defense's reputation for quality craftsmanship backing every product, you can trust that your equipment will perform when it matters most.
