Although not a big surprise given hints here and there, SOCOM has canceled the Mk16 in favor of focusing on the Mk17. I hope this forces FN to try to recoup some of their efforts and perhaps bring the common receiver design (and parts) to the civilian market. I would purchase the 308 SCAR in a heartbeat if it meant I could swap between 7.62 and 5.56.
