I have a Marlin 1894CL in 32-30 and I have always thought it would be great if it would have come with a full length magazine tube, I spotted an article on the internet where a gunsmith did a conversion to a full length magazine tube but in the article it didn't state where he got the new magazine tube and spring for the project. Has anyone done this and if you have what magazine tube did you use? The current short magazine tube has an outside diameter of .561"
