I have some (.094 wall thickness DOM tubing) which are counterbored for the rear plug, have the charging handle slot and the J-Slots in the rear cut out. Everything else is laser marked. $75

any one knows where i can buy a reduced dimeter tube for mk3 for semi auto build thanks captred
There used to be a book for sale at most gun shows about how to build a sten MG that had a paper template in the center. You can use that template on the outside to locate all the slots and holes, but use a thicker walled tubing so you can't install the original bolt (to help you stay out of Club Fed for having an unregistered machine gun).
