we open bolt kits

i see that TA has both the standard and CQB open bolt kits with only the standard M4 length version in stock.

I need this kit however i have the CQB version of the M4.

Is the only difference in those two open bolt kits the inner barrel length? I don't mind gaining some inner barrel length if i go the standard kit option.. are there any other differences in the two kits besides the barrel length?
