mine came with a 14 inch zero gravity barrel, hvc, expansion chamber, and venturi bolt so it was pretty consistant and accurate.
First off this gun has a lot of kick. This makes it hard to stay accurate during long strings. The trigger is not very good and has a long hard pull . The worst thing is that if you chop a ball you have to strip the maker down and try and unjam the bolt and clear out any paint that is in the top camber. This take about 15 minutes and after you do that the marker isnt nearly as accurate until you wash it out with under a sink.
If it did not jam every time it chopped a ball this would be a much better gun. But as it is I wish I had bought a spyder instead of this.
