WTK: FN FNC barrel twist rate?

[boofus]

I got a pre-import ban Howco FNC para with 16" barrel coming in soon. I've been wondering what the barrel twist rate is? I've read some of the FNCs had 1:12 barrels for use with M193 ammo, but others had 1:7 for SS109 and M855 ammo.

Anyone know anything about FNCs and can shed some light on what kind of barrel I have?

boof, should be marked on the barrel, right? Think mine are marked. I'll check when I get home.
