Kevin can probably shed a lot more light on the SCAR than I could, but IMHO, I think the SCAR looks like a robust and capable weapon system. I like how modular it is, and I like the option of putting different barrel lengths / calibre combinations together. Granted, I don't know how the SCAR stacks up against other 'next-gen' weapons like the HK 416/417, the XM-8 and the FN-2000 (to name a few), but it would be interesting to see if it makes the list as a potential C7 replacement.
