I'm looking for a drawing of a 7.5" barrel with all of the lengths and diameters listed out. I know the step for the FSB is 3.6" and the and the gas port is .295 beyond that, but I need the rest of the specs.

Something like this but with the numbers filled in and the contour corrected:

1" to the gas block(or .980 if you want some room) and .750 past(or .74 if you want some clearance). Gas block .750" diameter is about 1.85" long I think.
You can certainly lighten it a bit by turning the barrel down before the gas block and after, I wouldn't go under .625 with a reasonable taper and 1" dia section after the extension. Same goes with after the gas block.

Does anyone have the dementions from the gas port to the barrel ends? I don't have the gas tube yet and would like to get this barrel ready to go when it gets here.
