.308 build question

[snoopygw73]

I am going to be building a .308 on a mega arms MATEN billet upper/lower set. i went to black hole weaponry to order the .308 heavy barrel and could only find a 308B barrel. my question is, what the hell is 308B? i am referring to the "B".

It means black.

It's a black barrel.

About 1.5 times thicker and longer than non-black barrels.

Oh. thanks. i was just making sure it wasnt some kind of new wild cat round that is impossible to find. in opposed to the typical .308 winchester, which is impossible find right now

Sorry, there was nothing true to my post. That is most certainly not what the B means.

Any idea what it means? does it fire the typical .308 round?
