So I've been reading up on gas port sizes and came across a chart for "milspec" GP sizes for different barrel lengths. I know we have established that Noveske uses Milspec port sizes, but according to the chart:
A 14.5-16" barrel with an outside barrel diameter of .625" (at the GP) will have a min port size of .063.
A 14.5-16" barrel with an outside barrel diameter of .750" (at the GP) will have a min port size of .070.
My first question is, aren't Noveske's barrels .750" at the gas port? Giving it a .070 GP size? Or is it still .063?
Secone, why would the diameter of the barrel change the GP size?
If you are using the chart I am thinking of, it is wrong.
First, there are really only a handful of "issued" weapons. The two most common would be the M4 (which uses a .063GP) and the A2/A4.
The thickness of the barrel has nothing to do with the GP size.
Since we know that the M4's GP size is .063, then when you go to a 16" barrel, you are increasing dwell time. This means that you need to reduce the GP size to around .061 IMHO.

Question for Grant or anyone else that has tried this stuff with and without the LMT enhanced carrier.
If a 14.5" barrel with 0.062" gp was cut to 11.5" and found to function/lock back using a standard carrier and H2 buffer...would there still be any benefit to trying the enhanced LMT carrier?
Even though the rifle is functioning with the standard carrier...would the enhanced carrier run cleaner or allow the use of lower-powered ammo?
I'm still a little fuzzy as to why you would need a carrier to BLEED off gas from a system that is "optimized" to shoot dedicated suppressed (meaning it already has less gas to begin with)?
Is it that you have optimized the system for use WITH the LMT Enhanced Carrier?
If you could drill your own gas port, couldn't you get the same effect with a smaller GP and a standard carrier (because you don't have the excess gas that needs to be bled off)?
What benefit does the LMT enhanced carrier give you that the standard carrier does not, that would make you want to use it instead of optimizing the gas port for a standard carrier?
