The two hurdles the SPC couldn't overcome was size to function through the legacy M4 and pressure. The new SIG was designed from the ground up for a new platform. Whether the new rifle is backwards compatible ie, swapping uppers I do not know.

Thr 5.56 has plenty of power, but too small of a bullet. 30 cal and above is the right approach. Only exception would be the anemic. 30 carbine. Myself personally. I refer .30 cal, namely the .308. I used it the Army and i still used it in the civilian world. Don't fix whats not broken.
