STEN SMG compatible DIY substitute magazine

grabcad

This is a STEN submachine gun compatible substitute magazine that can be easily made at home from section of 35x35x1.5mm metric square tube, and a piece of 20x20x1.5mm square tube for the rear wall. I designed this magazine, because original STEN magazines may not be available in some countries with oppressive regimes, and this type of magazine is used in most submachine guns, designed for clandestine manufacture such as Bill Holmes' and Gerard Metral's designs, which are widely proliferated by their books. I don't make guns, this magazine is 100% CAD designed, so it may need some minor changes if made from metal. For example, follower design should be checked if it ensures against nose dive feed issues, spring wire thickness may be changed to 1.3mm, etc. Please comment and write suggestions for improvements. I may also upload ready to print templates in .pdf format, when I have the time to make those. File may contain some irrelevant data from previous design, I will purge it some day, but am too busy right now.
