What do you mean by "straight pipe" ? as in no rifling or light weight barrel as in non-M4?
Ok why does no one make a 10.5" 556 in straight .625 pipe?
I mean seriously with a redimag you might have 60 rounds on you, your not going to burn it up what gives? Is there a reason for this?

The diameter would have an exterior diameter of .625" down its length. Of course, I'm sure he is also allotting for the necessary shoulder for the gas block to be locked in to the proper position on the barrel to match up with the gas port.
As for the OP's question, I have no idea. If I find some time, I'll hunt around for one. Any other requirements as to twist rate/rifling style (5R, etc)?

.625 under the gas block and to the threading. They all bell out at the end after the shoulder and I don't even want a big shoulder.
1/7 or 1/8
1/9 for that short of a barrel doesn't seem to work all that well. I want something like this, have one of these on my teaching guns and its fantastic. Spike s Tactical 14.5 5.56 Mid-length LW NFA Pistol Barrel
Shortest one like that spikes makes is 11.5 I need an inch shorter

Might be several reasons. Most threaded barrel blanks are the same outside diameter end to end. Maybe the pistol barrel makers are just using left over cuts offs? How about botched rifle or carbine barrels cut off and reused? Or the barrel manufacture gets the blanks just the way they arrive? Also ... like already said better, there are only so many gas block diameters. Many possible reasons. My Green Mountain .22rf barrel is the same outside diameter end to end, but that is a different animal. HB of CJ (old coot)
Man, this one is close, but .750" diameter at the gas port.

I'm sure you're gaining no more than an ounce or two and a better selection of gas blocks if you went with a .750" barrel like the DD above...
EDIT: Dang, this one is 1/9 twist:
- 10.5 Light Weight Barrel
EDIT 2: I'm thinking the additional material of the .625" gas block will negate most of the weight savings gained from going with a true .625" profile as compared with a .750" like the 10.3" DD barrel. Thoughts?

GT john I'm running a lo pro gas block so no. But now i get why they do it.
its that diameter past the gas hole so it can have a F front sight post... makes sense just not what I want.

Your lo-pro gas block will still need to reach a standard height for gas tubes to interface with it. It's your rifle, but I'm a little confused as to the abstinence against the DD barrel. Meets all the other requirements, and you know it'll be a quality unit as well.
I'm just confused because all I can see the .625" profile barrel being worth is weight savings, and there won't be much of that compared to the other, widely available and good-quality barrels out there. Could you clue me in why the .625" profile is so critical?

weight and I can't help but think thats a little pricey for a pistol barrel, but your right it will work if I need it thanks.Your lo-pro gas block will still need to reach a standard height for gas tubes to interface with it.

Still deciding on options
By all means get what you want, but if what I want was so hard to find, I'd probably get into obtaining weights from different barrels to see if it's worth the ass pain.
Here's another: 1/8" twist, QPQ, 5.56NATO, but currently out of stock. Cheaper than the DD barrel, too.
