Because of a contractual agreement I am not at liberty to say, sorry.

If you know what you are doing and have the right tools the testing can be done in a day. You have an issue with us and I was informing you of how your assumptions were incorrect and how we do test every gas system for functionality with a variety of ammo on both buffer systems at all lengths because all lengths are different. And we will happily answer any question that we can but most companies ask for a Non Disclosure Agreement before they give out gas port information because that is expensive info to attain.

Hello everyone!, I am speaking on behalf of X-Caliber Barrels and Mfg. We do test our port sizes on every gun we sell. To assume that we guess all these things is ridiculous. We test our gas ports with a carbine length gas buffer, buffer tube and spring and then with the rifle length gas buffer, buffer tube and spring. And for everyone wanting to know gas port sizes, those are and industry secrets that are very valuable. Why are you asking for them, because no body gives them out. If they did the info would be all over for everyone to find but it is not because it is very valuable info. The gas port sizes you guys are referring to from other companies, are these Armalite or DPMS? Is it DPMS Gen 1 or Gen 2? As all of these have different tolerances and and call outs, THEY WILL ALL DIFFER. Did you know if the changes by .001" it will change your gas port size by .010"?!? Did you know changing your twist can change your gas port size .004"?!? There is so much to gas porting and thinking what works for one barrel will work for the other, may work in some situations, but not gun barrels. We have a company that takes 100 LR308 .308s a month and they consecutively ding metal at 900+ yards with no gas porting issues, same barrel that is being discussed. You can guess wrong about someone all day long but if you actually asked them there is no need to.
