sighting in a gws100 fiber optic mciro-sight
i just bought a new gws pro hunter micro-sight, giver optic. i am trying to sight it in but it is shooting low, i have it adjusted down as far as it will go. i don't use a peep sight. this has me confused. i also bought a quick tune 3000 arrow rest and put it on. i was using a whisker bisket and am wondering if i have not adjusted the quick tune correctly, bought it used, no instructions, although i did lower it and was still shooting low. can anyone help or direct me to a sight where they show how this sight works.
