This might make a nice 3-level dip for ranged rogues, since Extended Precision (as written) also applies to sneak attack. Don't know whether you like that or not.

Be advised that increasing the threat range is mathematically a better option because bows have a x3 crit multiplier already.

Rangers also get Manyshot in their combat style, at 6th level. Conveniently, this means a pure archery-style Ranger will already have Manyshot by the time it qualifies for this class.

And since you have to be at least at BAB +11 when you get Rapid Precision, Manyshot already gives you more arrows. It's true that Manyshot still only works with a 30-foot range, but honestly I'd just give the class Manyshot as a bonus feat and say Ranged Precision applies to Manyshot, rather then invent another use of Rapid Shot.
