I was trying to find out where my Kraken stood in terms of its accuracy, and what barrel I could switch to. I found that most of the stuff on accuracy of various barrels is very subjective, based on the guy shooting by hand and the terms describing groupings and distance are pretty variable.

I also found that it's rather hit and miss with tightbores and stock barrels: the accuracy depends ultimately on the barrel itself, not the make of barrel. Some stock TM barrels outshot some tighbores in terms of accuracy, and some tighbores turn out to be lemons. Some other airsoft site said that the very used (many tens of thousands of bbs) stock barrels of any make are the most accurate, when they are highly cleaned.

I was wondering if there is some kind of standard measurement for accuracy for barrel/hop-up combinations? For example, a gun held on a vice or stand can shoot a grouping of X inches at X feet, with X brand of bbs. Such a standard would be useful. Then we would know if we have a duff barrel or if we got lucky and it's not worth switching to a tighbore, for example.

another question:
What grouping do stock Tokyo Marui AKs manage at 60 feet, gun held fixed firmly as possible, with good bbs? I am assuming TM barrels and hopups are at least fairly consistent in terms of QC, so they can reliably post results with a low standard deviation?
