The lens sit very stiff and i can’t get it out by hand, I tried heating it up but does do anything, is it even possible? I don’t want to damage it either. Thanks

First you need to unscrew the bezel. Then you place a piece of wood on top of the aspheric lense and whack it with a hammer. Hopefully it will just pop out.

thanks , popped out, used a plier and two pieces of wood. Now how do i pop it back it firmly ?lol wish i had a c-clamp

I could just press it back in when I did this some time ago. Maybe I used a little brute force that's all.
