All righty guys new to bow hunting. But not to hunting. I have shot many bows and im pretty good with one. I do believe I could kill a deer with one. So I thought I would try this year. I recently inherited my brother and laws bow. Have no Idea what it is but it shoots. The draw length is a little short but once I get a release it should be about right. My question is he has a crappy looking sight on it. Dont no if he made it or what but I want to put a new sight on it and make sure I get a good shot. So is there a bunch of different ways to mount them on the bow or are they all the same or what. Dont what to spend alot just going to go to wally world and pic one up. Just wondering if any will fit or do I need a certain type?
