The Geissele MK16 Super M-Lok 13.5in Modular Rail has an internal diameter of 1.26". Meaning any muzzle device that does not exceed 1.26" in diameter will be compatible. A blast can like the Midwest Industries 5.56/.223 Aluminum Blast Can has an outer diameter of 1.2" and would be compatible. It can be found by using the link below:
