Fortis Gas Block M2 .750

The Fortis Gas Block M2 .750 is a precision-engineered gas block designed for AR-platform rifles requiring a .750-inch diameter tube interface. Built by Fortis Manufacturing, Inc.—a trusted name in high-performance tactical components—this gas block serves shooters who demand reliability and accuracy in both professional and competitive environments. The .750 size specification positions this component for use on mid-length to rifle-length gas systems, making it ideal for shooters running heavier ammunition loads or suppressed configurations where consistent gas regulation is critical.

The Fortis Gas Block M2 .750 features a low-profile design that minimizes sight-line obstruction while maintaining robust clamping force on your barrel's gas tube. The M2 designation indicates an optimized second-generation platform with refined geometry for enhanced durability and repeatable performance. Fortis manufacturing standards ensure tight tolerances and consistent material quality, reducing point-of-impact shift and improving zero retention across extended shooting sessions. At just 0.06 lbs, the compact footprint (4.5 x 1 x 5.75 inches) integrates seamlessly into standard AR-15 upper assemblies without adding unnecessary weight to your setup.

This gas block is essential for shooters building custom rifles, upgrading existing platforms, or replacing worn components in duty weapons. The .750 bore diameter makes it compatible with most quality barrel manufacturers' gas tube offerings, provided your barrel is chambered and drilled to accept this standard size. Installation requires basic gunsmithing knowledge—proper alignment and torque specification are vital to achieve the precise gas regulation this component is engineered to deliver. Whether you're running a precision rifle, carbine, or magnum platform, the Fortis Gas Block M2 .750 delivers the consistency and durability that separates field-proven components from budget alternatives.
