I have shot the Optix LE for a couple of years now with no problems. I absolutely love these sight. A friend of mine shot my bow this weekend and really liked them and decided to get the same ones. He called three different pro shops to check on them, and all three told them that the G5 LE is the most returned sight they sell due to breakage or the pins rattling. I have two other friends that have these sights and neither of them have had any trouble. I was wondering if anyone that shoots these sights have had any trouble with them. If so, what? Thanks.
