Not sure how good of a group you are looking for but I bought an 18" AA barrel from a forum member a couple years ago and it has no problem hitting a 12" plate at 600 yds. I got the barrel for the sole purpose of a hunting gun I built my fiance.
ETA
The barrel I was referring to is just the basic ER Shaw kit. I think the Spartan is a step up from it.
