I had a LE and it had a twang, sent it back to G5 for a ME, had a twang too. Got fed up....bought a spot-hogg. I don't want to have to mess around with making sure the top screw is tightened just perfect or I might get a twang. I think a lot of the twang comes from the sight being made from magnesium. it is so light that it is like it has no density, causing it to vibrate and twang. I like G5 products overall, but this sight needs more engineering!
Keep your reciept!
