Yup! Take the bezel out, take the lens, take the o-ring and then tap with the flashlight in your hand, with the lens down.
If you cannot remove it, try a toothpick or something pointy but not hard to alleviate the TIR on the sides. Then tap again.
It is not glued nor stuck, but the holes in the MCPCB and even the thermal paste below it may be hindering it from coming out.
Try the toothpick gently around the TIR, without much pressure 
If you have a suction cup, you can also attach it to the TIR and try to pull it out!!
