Here is how it goes.

I just increased the draw weight to 70 lbs - bow was still hitting dead on as it was at 60 lbs.

now my sight is twisting to the forward and to the right.

It is as tight as it is going to get.

Bow sight - Trophy ridge 2006 model.

Arrow fletching is not hitting sight as I thought that was what was doing it.

Thanks,

Logically speaking it could be riser flex but then again not so much. Risers are usually milled out of solid pieces of metal of some sort. What type of bow are you using? How old is it? I assume that it is and has been well taken care of, is that true? I haven't ever heard of such but a little more info would help make a guess and then we'll see what we can do to help you find the problem.

I figured it out and figured that it was something so simple that is why it was so hard to figure out - new bow new everything - the sight on one of the grooved sides was backwards - I guess the increase in draw weight had enough kick to make it move.

I guess the fletching does hit it a little....

Thanks,
