Theoretical: The SOCOM M4A1 post-adoption of the FN AC

[Spartan198]

^Don't worry, I know weren't. I am just a civvie, though, so I'm going to leave such analysis up to the guys who use the weapon. But the fact that armed forces all over the world are running, and in some cases have been for years on end, DI guns like the M4 without mass failure, should speak for itself IMO. I don't need to have carried the weapon into combat to know that much.
