Hi mate sorry for the delay in replying I had to double check the size, they are definitely 18mm and fit my foresight perfectly.

I now use Centra High End glass elements - these screw directly in the FWB tunnel : I use them on my FWB300 (not 'S') and 300SU, and they work a treat :

There is also a chappie here on 'BBS - harvey_s, that makes custom perspex sight elements to order.

Have fun
