6.03 or 6.04 for G23F?
 

What size is best?

It really depends on the bbs you use. Don't use cheap ones with it.. But, if you use High Quality bbs, I'd go with 6.03. But I'd ONLY get a tightbore barrel if you don't use the cheap ones.
Good Luck !

this seems like an interesting question. to add, if i may, is there a noticable difference between the two in short barrel pistols and smg in terms of grouping in all ranges(short-long)? is the cost difference (although it seems negligble) justified to get the 6.03?

It definitely tightens up groupings, increases shot consistency and tightens up groupings.

Tight is good.

Tight issss good... 8)
and BTW...thanks for the smooth transaction the other day!

oh yeah, it increases velocity as well. :tup:

What about a 6.01?? ;) ;)

Drop my buddy Dwayne at www.deeescustoms.com a line. His tightbores are very kickass and will do wonders to your GBB. **Be sure to check about velocity increases and make sure it won't blow your fields FPS limits, etc.

its a dead link!
