SIG SAUER M400 SDI SBR RM400-SDI-11B-SBR-B UPC 798681733507

The SIG SAUER M400 SDI SBR (Model RM400-SDI-11B-SBR-B, UPC 798681733507) is a high-performance short-barreled rifle built on SIG Sauer’s proven M400 platform. This compact and maneuverable SBR features an 11.5-inch barrel and is designed for users who require maximum performance in a reduced overall length. The M400 SDI SBR delivers the reliability, accuracy, and modularity that SIG Sauer is known for, making it an excellent choice for tactical professionals, competitive shooters, and serious enthusiasts who have properly registered their firearm under the National Firearms Act (NFA).

Why the SIG SAUER M400 SDI SBR Stands Out

The SIG SAUER M400 SDI SBR stands out as a factory-configured short-barreled rifle that combines the legendary durability of the M400 series with the compact size and handling characteristics of an SBR. The 11.5-inch barrel significantly reduces the overall length of the rifle compared to standard 16-inch models, improving maneuverability in confined spaces while maintaining excellent ballistic performance. The SDI (Suppressor Direct Interface) model is engineered with features that optimize suppressor use, including a direct thread or compatible muzzle device. Built with SIG Sauer’s commitment to quality, this SBR offers a robust, reliable platform that performs consistently under demanding conditions.
