Will any arrow rest mount on any bow or are there form factors I need to worry about. Same question for stabilizers, limb savers, sights, etc...
The Archery Manufacturer's Organization (AMO) has standardized mounting hardware for accessories so that one sight or rest or whatever can go on any bow. The things you need to watch out for are mostly with rests, you may be able to mount it to the riser but it may not function correctly on one bow while it works fine on another. Also some sights may not have enough run out to adjust for the extreme outside centershot of some bows (specifically the '08-'10 Elites that had center shots out to 15/16" from the riser, and maybe others that I don't know about.) So, in general, yes they'll mount, but it doesn't mean they'll work right.
