In addition to Patrick's question already asked, what is the inner diameter (for a recessed blast shield, suppressor, or linear comp)? Expert Answer

FosTech Outdoors does not provide the internal diameter of their MACH-2 AR-15 Tactical Rails. I'd recommend reaching out to them directly for more information. Their contact info is linked below:
