Need help with a Bofors 40mm breach.

[Brad Deckard]

Now I understand... Apologies I was in Bofors mode!!
As you say you will need to modify it to fit and function...
I am glad that you got it stripped down...
Send me a photo when you finish the conversion..!!
The breech will fire off when closed, I am sure it can be modifed to not fire.
You could also message that chap on the film you shared here and ask him how he holds back the pin..
Glad I helped you up to now..

Brad
