I would like a bit of advice/opinion on a small modification.

The front sight can easily be replaced with a 470TH style sightless weight but you will need to change the cocking lever as well.

Thanks for your suggestion but it's not quite a straight swop of the two parts, also I like the single ball lock up and it would be expensive with the price of the lever, a custom part might be cheaper
