I read that same article I think. Mentioned the A2 grip as well.

The "government" barrel profile makes no sense and should be phased out for "SOCOM" profile barrels or ones that taper down towards the muzzle.

I'll tell you this though, I was super impressed with the Colt SOCOM barrels. Very accurate. 1.25 moa roughly with m855 and sub moa with mk262. That's great for a non hammer forged chrome lined mass production barrel, especially back then.
