If someone want to get rid of a 'broken' drum mag, I can take it and open it up to see if a 3d designed mod can help with the missfeeds etc.
This drum would be a guinea pig, so I don't expect to pay retail for anyone 'volunteering' one to sell to me.
If in the Ottawa region, even better to save shipping.
This might also be of help for the straight magazine project I have on the go.
