Martin Jaguar Peep problem
I have a Martin Jaguar that I have had the same problem with since I purchesed it. The peep sight almost always twistes to the right after every shoot. sometimes to the piont that I have problems getting a good sight picture. I have replaced the string twice and have had two bow shops scraching they're heads on how to address the problem.
I'm using a Zero Peep with rubber tubing.
I would change to a new peep like a tri slot or shurz-a-peep if I thought it wouldnt twist on me during the hunt.
are you sure it's not just your string stretching. on new strings your peep will tend to turn until it is broken in
Once the string is broken in like buckshot said you should be able to twist you string and get it lined up properly.
