Go with the 6.03 not only are they cheaper but the accuracy difference between the two is almost unoticable, systema has even started labeling their .03's and .04's as their "accuracy barrels".

And Sooo much better.

OK, timeout, you guys are making my head spin.

First off tanaka's DO NOT have stock 6.01s. Second, all the tight bore barrel does is increase the air/gas pressure inside the barrel propelling the bb' faster. Third, there is a bigger difference between 6.03 and a 6.01 than a 6.05 and a 6.03. And finally,

HE ALREADY BOUGHT THE BARREL FOR CHRIST'S SAKE!!

God love you all but you guys need to know when to stop.

And dooooodsteven, there's a modify button in the top right hand corner.
