Looks like it could be opened, though I've never tried. Taping it or holding it down helps reducing the noise a bit, though I'm unsure if it's the part of the shell itself or something inside is rattling.
Didn't check specifically but as far as I remember the Rival also had a similar slight rattle.
Sorry, but you are wrong in this regard. Yes, the bottom part of the 3310 sensor, where the so called "eye" is placed, it does move but for around 10 to 15 cents of a millimeter, which is not enough to generate the rattle noise, unlike the logitech g400, if you ever try to dissable a g400 and check the 3095 sensor bottom part, you will notice that it does move for almost a half of a millimeter, and yet again not enough to generate the rattle noise since it is a small and extremely light part, where as the lense that moves for almost a millimeter, it does generate the sensor rattle.
And another yes is for Wareya who is right. There is nothing wrong with the kpm beside the lense rattle, where in a previous post I explained that in some KPMs there is more and some less, but not enough to change the performance of the actual sensor.
