10M sights

[wonky donky]

Just obtained a FWB 601 with the standard sights.

I'm looking to see if an upgrade is necessary / useful at this stage. I understand a 1.5x lens is within the rules. Is an iris and filters something I should be using?

Any help and advice appreciated.

Cheers

Perhaps a variable iris is in order to get a better depth of field, any magnification in the standing position is going to magnify movement also which in turn will make getting the shot off much more difficult.......If you have a 9.5 hold or better then you will probably be ok. Filters can be of use but rarely indoors.
