same thing happened to me last week, I just gotten my new buckmaster G2, installed everything and I have a very low nock point, called buckmaster and they could not give me a good answer, so they said to send it to us and we will se what is wrong. I sent to them and I wanted heaver limbs (70-80 lb) and the tech who worked on it said no problem ,free of charge, they found the rest prongs out of wack causing the low nock, and I ask if I could get 65%module in the 29 and 30 inch and he said no problenm free of charge, they even gave me two types of cable guards with the shock stop installed and said to try 1 and see which I like better and to keep the other one, free of charge.. and then send back overnight free of charge....
