Sons of Liberty Gun Works 16" Mid Length CHF barrel

[og556]

I'm interested in the Sons of Liberty Gun Works 16" Mid Length CHF Barrel. I like mid weight barrels and the fact that this is a cold hammer forged barrel. Any idea if it is an FN barrel with double chrome lining ?

From the picture on the website it looks like it is a mid weight barrel (similar to Colt SOCOM profile ?) up until after the gas block where it tapers into a lighter profile.

Also, could any one tell me what size gas port this uses ? I am trying to decide between one of these and another Noveske 16" CHF mid legnth. I'm trying to find something with a smaller gas port if possible though.
