Does anyone know the size/pitch/designation of the threads at each end of the M37 mag tube, the fine thread at the receiver end and the coarse thread at the mag nut end. (its a '71 if that is relevant)
I ask because I need to make a custom length tube for my competition gun (10 + 1 capacity) after a minor accident dented and bent the original custom tube. I have straightened the original and it works fine but it appears a little fragile (thin walled) and I should like to make a stronger repair/upgrade.
Here's hoping the Ithaca massive has the info!! :)
