Take a look at this...

OK, I'm thinking of getting this barrel. I want to put a standard A2 Frontsight/Gast Block on it. By looking at the picture, can you experts tell me if I need a .75 or a .625 Front Sight/Gas Block?

Here's what I want to put on it

Looks to be a medium profile stainless barrel. You would need a .750" front sight base.

You need.750.

With that said, you know that you cannot take a barrel with existing FSB holes & install a FSB off of another barrel right?

Barrel looks a little short. Wouldn't you need an "F" FSB instead of an "A2"?
