When I get around to stocking 18" 6mmARC barrels, they'll have a RLGS like my 18" Grendels (when I get around to restocking them). In production now are 6ARC 16" and 20" and 65G 14.5".
Having said that, I don't think the 6ARC using CFE223 or LeveRevolution powder needs a non-standard gas tube length any more than 65G using those powders. And having said THAT, barrels longer than 20" in 556 and 65G and 6ARC probably should have always had RLGS + X. I don't know that from experience, just remember Bill Alexander hinting at that.
Yesterday was out function-testing my 6ARC 12" barrel and its CLGS ejected beautifully. THEORETICALLY, gas port locations can be tweaked as much as gas port hole diameters, and you could end up with a million different gas tube lengths. However, if the intention is to keep things simple and use standard tubes, the key is properly sizing the gas port and it works perfectly well in PRACTICE.
