I would imagine he's referring to the SOCOM elements that already use SF 4 prong muzzle devices. And the simple answer to that question is that SOCOM has already procured an SF muzzle device and it wasn't the Warcomp.
Procurement, even for SOCOM, isn't exactly a simple, easy, or inexpensive process; there would need to be considerable benefits to even remotely justify upgrading. They can't just snap their fingers and suddenly replace the muzzle devices (or any other accessory) on thousands of guns just because something new came out, even if it might be arguably better.
Individual units could potentially purchase them, but a widespread transition across SOCOM to swap to another muzzle device that would offer little if any meaningful improvement over the existing one in terms of combat performance just isn't likely to happen.
