Depends on the paint/barrel match, same with every other marker. The regulators is pretty consistant and really would be the only determining factor of how the grouping is compared to other markers with the same barrel and exact same size paint (which no paint is ever the same size anyway). On that note, its just as accurate as any other high end marker shooting a non perfect mostly round paintball at 200 mph.
