Need help with a Bofors 40mm breach.

[Jon Bradshaw]

I now have a clean and functioning breach. It took all day and involved a few blocks of wood a sledge hammer and some ingenuity.
I cleaned the parts and put them back in to check for function and the bolt fired once it reached top position as expected.
Since this is not going to be in an auto firing "AA" setup but in a tank gun installation this is not ideal for me. Is there a common mod to stop it from firing once it closes or is this something that I will need to make from scratch?
I need to mod out a trigger for it along with this so I am curious if it has been done by anyone on this forum before?
I found this on you tube and it seems to be exactly the mod I am trying to do.

I will put up some more pics once it is all clean and shiny.
