Why 6.01mm?
With the 5.99mm and 5.98mm bbs going extinct, and with present day match grade bbs being 5.88~5.95 for a better center of mass, 6.01mm became the new optimized bore for maximum range, grouping and accuracy.(BB Diameter Deviation Reference: Tokyo Marui / Excel (5.90+). KSC/Evike Japanese Spec. (5.88+). Matrix, WE, AIM Top, Madbull, Elite Force (5.90+).
6.01mm barrels also provides less air volume in the barrel, resulting less air needed from the cylinder for each projection.

Inner Barrel FAQ: If you greatly increase the inner barrel of your AEG, you may want to make sure your gearbox Cylinder is adequate. (For example, if you install a 509mm inner barrel on your MP5, you may want to switch the cylinder to a full cylinder so the amount of air inside the cylinder is equivalent to your new barrel.
