I have a no.4 mk.1 Enfield with a junk barrel that i would like to turn into a hybred L42. The finished rifle would have the looks of the L42 but would be in the original .303 caliber. I believe this would simpilfy the whole process and keep the costs down as well. Is the barreling process with the NO.4 fairly straight forward or are there some quirks i need to know about? Share your thoughts. It will be interesting to see what others think about this project.
