I bought years and years ago a sten mark3 parts kit with the barel,15 mags and a friend bought the reciever tube with the template on it. I had the intentions of making it semi auto but never did do anything with it. I did keep the parts seperate becasue I was not sure about legality becasue they were not sold with the mags,or the tube. My question is can they all be in the same place if the tube is not cut out? Also does anybody make a good kit to make these into there semi auto configuration? I just want to make sure I dont do something stupid.
