Ranger feats

[Nicos]

lets say a ranger take the archery combat style and at six level he take improved precise shot.

Then at ten level can he choose to take manyshots or do he have to choose from the 10th level list ( Pinpoint Targeting and Shot on the Run)?

[Happler]

From my reading the list just gets bigger each step (2,6,10) so that by level 10 you would get to choose any of the following feats:

Far Shot, Point Blank Shot, Precise Shot, Rapid Shot, Improved Precise Shot, Manyshot, Pinpoint Targeting, and Shot on the Run

[Michael Sayre]

Yes, you add each new tier to the feats already available to you:
"If the ranger selects archery, he can choose from the following list whenever he gains a combat style feat: Far Shot, Point Blank Shot, Precise Shot, and Rapid Shot. At 6th level, he adds Improved Precise Shot and Manyshot to the list. At 10th level, he adds Pinpoint Targeting and Shot on the Run to the list.
