is the ACI barrel you have good for accuracy and stuff. Im getting a
new barrel soon. The ACI is cheaper than the smart parts AA barrels but
about the same as an ACI. if you had a choice would you get a smart
parts progressive or an ACI. I'll probably end up getting both but for
a cheaper barrel i can get sooner with my budget right now i might go
for an ACI barrel. About your question, im not sure but it doesnt sound
like it is finished since all barrels are supposed to be smooth and
shiny when you buy them. My stock tippmann barrel had no smoothness to
it when i got it but after shooting about 400 rounds through it it
smoothed out abit. maybe j and j come with rifling but it should still
be shiny new inside.
