I found this for Oregon.


Archery
[ul][*]Broadhead blades must be fixed, unbarbed, and at least 7/8” wide (except for western gray squirrel). It is illegal to hunt with or possess mechanical or moveable blade broadheads when hunting game mammals except Western gray squirrel.[*]Beginning in 2006, there is no restriction limiting the maximum let-off for compound bows used for hunting in Oregon; since 1990, let off had been restricted to no more than 65%.[*]No device secured to or supported by a bow may be used to maintain the bow at full draw.[*]No electronic devices may be attached to bow or arrow.[*]No device that supports or guides the arrow from a point rearward of the bow string when the bow is at rest (undrawn) may be secured to or supported by a bow’s riser. Overdraws meeting this restriction are legal during archery seasons. [/ul]
