What's the term for those barrels that are machined in a way that looks like a honeycomb?  What's the official name for that?

Anyone know what I'm talking about?

Machined on the outside?  
Hammer forged?

fluted?

machined on the outside.  a pattern kind of like the divets on a golf ball, would be one example. A weight-reducing method. I saw some picture of a barrel with that a few weeks ago.. and mr. man and I were wondering what it was called. Maybe it was some custom thing?

I have seen a couple of rifles done like that.

very hard/tedious to do.

Dunno if anybody really does it regular though.

It's called a jeweled barrel  

ETA:  No it's not....

Milled.  Usually ball mill.  To turn the ball mill pockets into hexagonal would require tedious broaching.  Wobble broaching would work

I don't know what its called, but it looks kinda goofy.

Would be a decent weight reduction method though.

Not sure if I would want any of my rifles like that.

It's called a dimpled barrel.

Don't bump this thread.  You might give   The Spaniard some ideas.  He has a dremel and isn't afraid to use it.

That looks like the barrel on the KAC "PDW" rifle, in some obscure caliber.

Interesting way of reducing weight, and increasing the surface area for heat dissipation though.

Actually, fluting with a thin kerf blade is better.  That milled dimpling isn't too good on stiffness.
